把redis-server.exe的路径加到系统的环境变量path里

启动服务

redis-server.exe redis.windows.conf

连接服务

redis-cli.exe -h 127.0.0.1 -p 6379

注意有时候会有中文乱码，要在 redis-cli 后面加上 --raw：

redis-cli --raw

退出quit：

启动脚本

@echo off
F:
cd F:\Redis
redis-server.exe redis.windows.conf 
exit

放在redis安装目录：

为该脚本创建快捷方式，点击即可运行。

添加认证服务模块

Oauth2认证服务，负责对登录用户进行认证，整合Spring Security + Oauth2。

在pom中添加相关依赖

主要是Spring Security、Oauth2、JWT、Redis相关依赖：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

        <artifactId>spring-boot-starter-data-redis</artifactId>
        <version>2.4.4</version>
    </dependency>
</dependencies>

在application.yml中添加相关配置

主要是Nacos和Redis相关配置：

server:
  port: 9401
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql:///dgut?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
    username: root
    password: root
  application:
    name: service-oauth2-auth
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
  redis:
    database: 0
    port: 6379
    host: localhost
#    password:

使用keytool生成RSA证书

使用keytool生成RSA证书jwt.jks，复制到resource目录下：

keytool -genkey -alias jwt -keyalg RSA -keystore jwt.jks

创建主类

开启服务发现，将认证服务注册到nacos中心：

package com.oauth2;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class AuthApplication {
public static void main(String[] args) {
        SpringApplication.run(AuthApplication.class);
    }
}

创建UserDTO

数据传输对象（DTO)(Data Transfer Object)，是一种设计模式之间传输数据的软件应用系统。数据传输目标往往是数据访问对象从数据库中检索数据。数据传输对象与数据交互对象或数据访问对象之间的差异是一个以不具有任何行为除了存储和检索的数据（访问和存取器）。

添加pom依赖：

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.20</version>
    <scope>provided</scope>
</dependency>

创建UserDTO类：

package com.oauth2.domain.dto;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;

import java.util.List;


@Data
@EqualsAndHashCode(callSuper = false)
@AllArgsConstructor
public class UserDTO {
private Long id;
    private String username;
    private String password;
    private Integer status;
    private List<String> roles;

}

加载用户信息

创建UserServiceImpl类实现Spring Security的UserDetailsService接口，用于加载用户信息。

添加pom依赖：

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.6.2</version>
</dependency>

Hutool是一个小而全的Java工具类库，通过静态方法封装，降低相关API的学习成本，提高工作效率，使Java拥有函数式语言般的优雅。

注入PasswordEncoder类：

@Bean
public PasswordEncoder passwordEncoder(){
    return new BCryptPasswordEncoder();
}

创建 SecurityUser类实现UserDetails类：

package com.oauth2.domain;

import com.commons.admin.entity.Admin;
import com.commons.enterprise.entity.EnterpriseAdmin;
import com.commons.student.entity.Student;
import com.oauth2.domain.dto.UserDTO;
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.crypto.password.PasswordEncoder;

import java.util.ArrayList;
import java.util.Collection;

/**
 * 实现UserDetails类，获取用户详细信息
 */
@Data
public class SecurityUser implements UserDetails {

    /**
     * ID
     */
    private Long id;
    /**
     * 用户名
     */
    private String username;
    /**
     * 用户密码
     */
    private String password;
    /**
     * 用户状态
     */
    private Boolean enabled;
    /**
     * 权限数据
     */
    private Collection<SimpleGrantedAuthority> authorities;

    public SecurityUser() {

    }

    public SecurityUser(UserDTO userDTO) {
        this.setId(userDTO.getId());
        this.setUsername(userDTO.getUsername());
        this.setPassword(userDTO.getPassword());
        this.setEnabled(userDTO.getStatus() == 1);
        if (userDTO.getRoles() != null) {
            authorities = new ArrayList<>();
            userDTO.getRoles().forEach(item -> authorities.add(new SimpleGrantedAuthority(item)));
        }
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return this.authorities;
    }

    @Override
    public String getPassword() {
        return this.password;
    }

    @Override
    public String getUsername() {
        return this.username;
    }

    /**
     * isAccountNonExpired()：当前账号是否已经过期
     *
     * isAccountNonLocked()：当前账号是否被锁
     *
     * isCredentialsNonExpired()：当前账号证书（密码）是否过期
     *
     * isEnabled()：当前账号是否被禁用
     *
     * 都要给设成true 否则登录会报出来
     */

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return this.enabled;
    }

}

该类通过重写UserDetails接口方法来设定鉴权用户信息。

创建常量类：

package com.oauth2.constant;

public class MessageConstant {
public static final String LOGIN_SUCCESS = "登录成功!";

    public static final String USERNAME_PASSWORD_ERROR = "用户名或密码错误!";

    public static final String CREDENTIALS_EXPIRED = "该账户的登录凭证已过期，请重新登录!";

    public static final String ACCOUNT_DISABLED = "该账户已被禁用，请联系管理员!";

    public static final String ACCOUNT_LOCKED = "该账号已被锁定，请联系管理员!";

    public static final String ACCOUNT_EXPIRED = "该账号已过期，请联系管理员!";

    public static final String PERMISSION_DENIED = "没有访问权限，请联系管理员!";
}

该类定义用户登录各种情况信息，用于封装各种异常信息。

创建UserServiceImpl类实现Spring Security的UserDetailsService接口：

package com.oauth2.service.impl;

import cn.hutool.core.collection.CollUtil;
import com.oauth2.constant.MessageConstant;
import com.oauth2.domain.SecurityUser;
import com.oauth2.domain.dto.UserDTO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AccountExpiredException;
import org.springframework.security.authentication.CredentialsExpiredException;
import org.springframework.security.authentication.DisabledException;
import org.springframework.security.authentication.LockedException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

@Service
public class UserServiceImpl implements UserDetailsService {

private List<UserDTO> userList;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @PostConstruct
    // 该注解被用来修饰一个非静态的void（）方法。
    // 被@PostConstruct修饰的方法会在服务器加载Servlet的时候运行，并且只会被服务器执行一次。
    // PostConstruct在构造函数之后执行，init（）方法之前执行。
    public void initData() {
        String password = passwordEncoder.encode("123456");
        userList = new ArrayList<>();
        userList.add(new UserDTO(1L, "macro", password, 1, CollUtil.toList("ADMIN")));
        userList.add(new UserDTO(2L, "andy", password, 1, CollUtil.toList("TEST")));
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        List<UserDTO> findUserList = userList.stream().filter(item -> item.getUsername().equals(username)).collect(Collectors.toList());
        if (CollUtil.isEmpty(findUserList)) {
            throw new UsernameNotFoundException(MessageConstant.USERNAME_PASSWORD_ERROR);
        }
        SecurityUser securityUser = new SecurityUser(findUserList.get(0));
        if (!securityUser.isEnabled()) {
            throw new DisabledException(MessageConstant.ACCOUNT_DISABLED);
        } else if (!securityUser.isAccountNonLocked()) {
            throw new LockedException(MessageConstant.ACCOUNT_LOCKED);
        } else if (!securityUser.isAccountNonExpired()) {
            throw new AccountExpiredException(MessageConstant.ACCOUNT_EXPIRED);
        } else if (!securityUser.isCredentialsNonExpired()) {
            throw new CredentialsExpiredException(MessageConstant.CREDENTIALS_EXPIRED);
        }
        return securityUser;
    }

}

该初始化生成一个管理员用户和一个测试用户，通过加载方法返回一个鉴权的用户对象，如果用户登录异常，就报各种情况的异常错误。

添加认证服务相关配置Oauth2ServerConfig

需要配置加载用户信息的服务UserServiceImpl及RSA的钥匙对KeyPair。

实现TokenEnhancer接口：

package com.oauth2.component;

import com.oauth2.domain.SecurityUser;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class JwtTokenEnhancer implements TokenEnhancer {
    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        SecurityUser securityUser = (SecurityUser) authentication.getPrincipal();
        Map<String, Object> info = new HashMap<>();
        //把用户ID设置到JWT中
        info.put("id", securityUser.getId());
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(info);
        return accessToken;
    }
}

该类用于往JWT中添加自定义信息，比如说登录用户的ID。

创建Oauth2ServerConfig：

package com.oauth2.config;

import com.oauth2.component.JwtTokenEnhancer;
import com.oauth2.service.impl.UserServiceImpl;
import lombok.AllArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;

import java.security.KeyPair;
import java.util.ArrayList;
import java.util.List;

@AllArgsConstructor
@Configuration
@EnableAuthorizationServer
public class Oauth2ServerConfig extends AuthorizationServerConfigurerAdapter {

private final PasswordEncoder passwordEncoder;
    private final UserServiceImpl userDetailsService;
    private final AuthenticationManager authenticationManager;
    private final JwtTokenEnhancer jwtTokenEnhancer;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("client-app")
                .secret(passwordEncoder.encode("123456"))
                .scopes("all")
                .authorizedGrantTypes("password", "refresh_token")
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        TokenEnhancerChain enhancerChain = new TokenEnhancerChain();
        List<TokenEnhancer> delegates = new ArrayList<>();
        delegates.add(jwtTokenEnhancer);
        delegates.add(accessTokenConverter());
        enhancerChain.setTokenEnhancers(delegates); //配置JWT的内容增强器
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService) //配置加载用户信息的服务
                .accessTokenConverter(accessTokenConverter())
                .tokenEnhancer(enhancerChain);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.allowFormAuthenticationForClients();
    }

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        jwtAccessTokenConverter.setKeyPair(keyPair());
        return jwtAccessTokenConverter;
    }

    @Bean
    public KeyPair keyPair() {
        // 从classpath下的证书中获取秘钥对
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource("jwt.jks"), "123456".toCharArray());
        return keyStoreKeyFactory.getKeyPair("jwt", "123456".toCharArray());
    }

}

该类是鉴权服务器配置，用于创建一个jwt的鉴权服务端，加载jwt.jks密钥文件，分发token。

通过KeyPairController把公钥暴露出来

由于我们的网关服务需要RSA的公钥来验证签名是否合法，所以认证服务需要有个接口把公钥暴露出来。

package com.oauth2.controller;

import com.nimbusds.jose.jwk.JWKSet;
import com.nimbusds.jose.jwk.RSAKey;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.KeyPair;
import java.security.interfaces.RSAPublicKey;
import java.util.Map;

@RestController
public class KeyPairController {

    @Autowired
    private KeyPair keyPair;

    @GetMapping("/rsa/publicKey")
    public Map<String, Object> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }

}

配置Spring Security，允许获取公钥接口的访问

package com.oauth2.config;

import org.springframework.boot.actuate.autoconfigure.security.servlet.EndpointRequest;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
                .antMatchers("/rsa/publicKey").permitAll()
                .anyRequest().authenticated();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

创建一个资源服务ResourceServiceImpl

初始化的时候把资源与角色匹配关系缓存到Redis中，方便网关服务进行鉴权的时候获取。

创建Redis常量类：

package com.oauth2.constant;

public class RedisConstant {
    public static final String RESOURCE_ROLES_MAP = "AUTH:RESOURCE_ROLES_MAP";
}

创建ResourceServiceImpl：

package com.oauth2.service.impl;

import cn.hutool.core.collection.CollUtil;
import com.oauth2.constant.RedisConstant;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import java.util.List;
import java.util.Map;
import java.util.TreeMap;

@Service
public class ResourceServiceImpl {

private Map<String, List<String>> resourceRolesMap;

    @Resource
    private RedisTemplate<String,Object> redisTemplate;

    @PostConstruct
    public void initData() {
        resourceRolesMap = new TreeMap<>();
        resourceRolesMap.put("/api/hello", CollUtil.toList("ADMIN"));
        resourceRolesMap.put("/api/user/currentUser", CollUtil.toList("ADMIN", "TEST"));
        redisTemplate.opsForHash().putAll(RedisConstant.RESOURCE_ROLES_MAP, resourceRolesMap);
    }
}

将资源与对应访问权限放到redis缓存。

AuthController自定义Oauth2获取令牌接口

封装API的错误码：

package com.oauth2.api;

public interface IErrorCode {
    long getCode();

    String getMessage();
}

枚举一些常用API操作码：

package com.oauth2.api;

public enum ResultCode implements IErrorCode {
    SUCCESS(200, "操作成功"),
    FAILED(500, "操作失败"),
    VALIDATE_FAILED(404, "参数检验失败"),
    UNAUTHORIZED(401, "暂未登录或token已经过期"),
    FORBIDDEN(403, "没有相关权限");
    private long code;
    private String message;

    private ResultCode(long code, String message) {
        this.code = code;
        this.message = message;
    }

    @Override
    public long getCode() {
        return code;
    }

    @Override
    public String getMessage() {
        return message;
    }
}

CommonResult通用返回对象：

package com.oauth2.api;

public class CommonResult<T> {
private long code;
    private String message;
    private T data;

    protected CommonResult() {
    }

    protected CommonResult(long code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    /**
     * 成功返回结果
     *
     * @param data 获取的数据
     */
    public static <T> CommonResult<T> success(T data) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), ResultCode.SUCCESS.getMessage(), data);
    }

    /**
     * 成功返回结果
     *
     * @param data 获取的数据
     * @param  message 提示信息
     */
    public static <T> CommonResult<T> success(T data, String message) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), message, data);
    }

    /**
     * 失败返回结果
     * @param errorCode 错误码
     */
    public static <T> CommonResult<T> failed(IErrorCode errorCode) {
        return new CommonResult<T>(errorCode.getCode(), errorCode.getMessage(), null);
    }

    /**
     * 失败返回结果
     * @param errorCode 错误码
     * @param message 错误信息
     */
    public static <T> CommonResult<T> failed(IErrorCode errorCode,String message) {
        return new CommonResult<T>(errorCode.getCode(), message, null);
    }

    /**
     * 失败返回结果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> failed(String message) {
        return new CommonResult<T>(ResultCode.FAILED.getCode(), message, null);
    }

    /**
     * 失败返回结果
     */
    public static <T> CommonResult<T> failed() {
        return failed(ResultCode.FAILED);
    }

    /**
     * 参数验证失败返回结果
     */
    public static <T> CommonResult<T> validateFailed() {
        return failed(ResultCode.VALIDATE_FAILED);
    }

    /**
     * 参数验证失败返回结果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> validateFailed(String message) {
        return new CommonResult<T>(ResultCode.VALIDATE_FAILED.getCode(), message, null);
    }

    /**
     * 未登录返回结果
     */
    public static <T> CommonResult<T> unauthorized(T data) {
        return new CommonResult<T>(ResultCode.UNAUTHORIZED.getCode(), ResultCode.UNAUTHORIZED.getMessage(), data);
    }

    /**
     * 未授权返回结果
     */
    public static <T> CommonResult<T> forbidden(T data) {
        return new CommonResult<T>(ResultCode.FORBIDDEN.getCode(), ResultCode.FORBIDDEN.getMessage(), data);
    }

    public long getCode() {
        return code;
    }

    public void setCode(long code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }
}

Oauth2获取Token返回信息封装：

package com.oauth2.domain.dto;

import lombok.Builder;
import lombok.Data;
import lombok.EqualsAndHashCode;

@Data
@EqualsAndHashCode(callSuper = false)
@Builder
public class Oauth2TokenDto {
    /**
     * 访问令牌
     */
    private String token;
    /**
     * 刷新令牌
     */
    private String refreshToken;
    /**
     * 访问令牌头前缀
     */
    private String tokenHead;
    /**
     * 有效时间（秒）
     */
    private int expiresIn;
}

自定义Oauth2获取令牌接口：

package com.oauth2.controller;


import com.oauth2.api.CommonResult;
import com.oauth2.domain.dto.Oauth2TokenDto;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.endpoint.TokenEndpoint;

多角色认证

增加mapper配置：

关于如何检验用户账号属于哪个角色

url传参，在账号后自动添加角色字段，如账号@ROLE，查询前，先做字符串分割得知role，就能决定调用哪个数据库去查询，只需要查一个表。

token字段中可以增加一级缓存，字段permission对应用户role，查询前，由permission得知role，就能决定调用哪个数据库去查询，只需要查一个表。

使用redis缓存，将用户账号和角色作为键值对缓存到redis中，每次查询前先从redis中哈希查询得到role，就能决定调用哪个数据库去查询，只需要查一个表。

从用户群体考虑，账号依次查询 学生、用人单位、学校 三个角色表。

关于资源与角色访问权限

是为了接口安全，不让角色越界访问非权限内的接口。其实也可以做一级、二级、三级缓存来做前置操作以区别不同用户角色对接口的访问权限，保证接口安全。

关于引入QQ/微信第三方认证

主要还是经费不足，才采用的传统邮箱认证方式，后续版本有经费的话会加入第三方认证。

搭建网关服务

配置网关服务，它将作为Oauth2的资源服务、客户端服务使用，对访问微服务的请求进行统一的校验认证和鉴权操作。

在application.yml中添加相关配置

主要是路由规则的配置、Oauth2中RSA公钥的配置及路由白名单的配置：

对网关服务进行配置安全配置

创建白名单配置IgnoreUrlsConfig:

package com.gateway.config;

import lombok.Data;
import lombok.EqualsAndHashCode;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.List;

@Data
@EqualsAndHashCode(callSuper = false)
@Component
@ConfigurationProperties(prefix="secure.ignore")
public class IgnoreUrlsConfig {
    private List<String> urls;
}

创建白名单过滤链IgnoreUrlsRemoveJwtFilter:

package com.gateway.filter;

import com.gateway.config.IgnoreUrlsConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;
import org.springframework.util.PathMatcher;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;

import java.net.URI;
import java.util.List;

@Component
public class IgnoreUrlsRemoveJwtFilter implements WebFilter {
    @Autowired
    private IgnoreUrlsConfig ignoreUrlsConfig;
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        URI uri = request.getURI();
        PathMatcher pathMatcher = new AntPathMatcher();
        //白名单路径移除JWT请求头
        List<String> ignoreUrls = ignoreUrlsConfig.getUrls();
        for (String ignoreUrl : ignoreUrls) {
            if (pathMatcher.match(ignoreUrl, uri.getPath())) {
                request = exchange.getRequest().mutate().header("Authorization", "").build();
                exchange = exchange.mutate().request(request).build();
                return chain.filter(exchange);
            }
        }
        return chain.filter(exchange);
    }
}

创建常量类:

package com.gateway.constant;

public class AuthConstant {

    public static final String AUTHORITY_PREFIX = "ROLE_";

    public static final String AUTHORITY_CLAIM_NAME = "authorities";

}

package com.gateway.constant;

public class RedisConstant {
    public static final String RESOURCE_ROLES_MAP = "AUTH:RESOURCE_ROLES_MAP";
}

创建鉴权管理器，用于判断是否有资源的访问权限:

import org.springframework.stereotype.Component;
import reactor.core.publisher.Mono;

import javax.annotation.Resource;

import java.util.stream.Collectors;

/**

     * 更好的选择。
     * 当Redis当中的数据值是以可读的形式显示出来的时候，只能使用StringRedisTemplate才能获取到里面的数据。
     * 所以当你使用RedisTemplate获取不到数据的时候请检查一下是不是Redis里面的数据是可读形式而非字节数组.

            }
        }

                .map(AuthorizationDecision::new)
                .defaultIfEmpty(new AuthorizationDecision(false));
    }
}

全局过滤器AuthGlobalFilter:

jwt鉴权测试

在此之前先启动我们的Nacos和Redis服务，然后依次启动test、api-gateway及oauth2-auth服务:

使用密码模式获取JWT令牌

方法
POST

接口
http://localhost:7000/auth/oauth/token

使用获取到的JWT令牌访问需要权限的接口

header加上key => Authorization，token之前加上“Bearer”

越权访问接口

当JWT令牌过期时，使用refresh_token获取新的JWT令牌

将grant_type改为refresh_token，无需账号密码，只需refresh_token：

{"code":200,"message":"操作成功","data":{"token":"eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJtYWNybyIsInNjb3BlIjpbImFsbCJdLCJpZCI6MSwiZXhwIjoxNjE4MTM2ODI2LCJhdXRob3JpdGllcyI6WyJBRE1JTiJdLCJqdGkiOiI4NDlkZmFjNi00NWY4LTQ0NzktYTdiMS1jNDlmYjkwYmRkODQiLCJjbGllbnRfaWQiOiJjbGllbnQtYXBwIn0.iDpy_AdHwVdMAsTVLZavCYlw1j6rBNc7uBF5ccymxtAYqx5lrSf5ipK1S6ZnZMWNgqhLYrU4-IHSpXZ0F7oNXrXIif1b1A6gi8_UPf9YQQrJY2B83DBjRJjIFwSSnLB1Ps3wHLhtse0kuI9shfmzXRpkh7DzOdyKcG088yh1p1YcopfQ68jeZkjr27XjCnRRmgb6ldWlRLX9UlI5Be1WSRKhmtHUPeUz7IwIAz5gNo98uSO-3euipBKxYxYYpi3TJu7jYAays4rcoYG_HJ_MTmU6XSaTyYuygSng5tDVQR0gwUC_vWEw90AExJV6df26ToRQnVpCebF1OpX2ApJAFg","refreshToken":"eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJtYWNybyIsInNjb3BlIjpbImFsbCJdLCJhdGkiOiI4NDlkZmFjNi00NWY4LTQ0NzktYTdiMS1jNDlmYjkwYmRkODQiLCJpZCI6MSwiZXhwIjoxNjE4MjE4NzgxLCJhdXRob3JpdGllcyI6WyJBRE1JTiJdLCJqdGkiOiI0YzJiM2U5Zi1mMDI2LTQ2MWUtYmQwNS1jZTBiNTE0YTY0ZTQiLCJjbGllbnRfaWQiOiJjbGllbnQtYXBwIn0.dL6Ggbv-1gMs_pD6OKesTITdJKVDv7_oBICYeog8-5ynK-E1cQFFqBwuoeLlx9zFPT_5mCfyf3HwZ9ptXQb3tJmpw7S9Z9t-iDvK-IeLIgHD-qrno3NXIATdjHR0ApE_6AewVjZzbXcThw04rJU_CG1qohP9xPgL8c_3_gE6hrgRXHrJ4QaCqpEc8a6CRmUqHZFIOLj-CspPYQgmHDbl-sBz1dy-W8dsLN34pUOasVPl1hpprgXSwvIzkbb3GIk3ZRTbj6ozFe7MTItJud9g5hT7yUksBYbekH75KW-1D8vTosGONsru2VcLqYgCsgmwqqfUa20u_lGn7u7uVtDeWQ","tokenHead":"Bearer ","expiresIn":3599}}

邮箱验证码服务

配置

创建配置类EmailProperties，从yml配置中读取配置：

package com.gateway.component;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component
@ConfigurationProperties(prefix = "yushanma.email")
public class EmailProperties {
    private String from;
    private String hostName;
    private String token;
}

创建EmailConstant常量类，用于封装信息：

package com.gateway.constant;

public class EmailConstant {
    public static final String CHARSET = "utf-8";
    public static final String NAME = "【余衫马】官方";
    public static final String SUBJECT = "【机器验证】";
    public static final String SENT = "已发送验证码，请稍后再试";
    public static final String EMPTY = "收件人邮箱地址为空";
    public static final String SUCCESS = "发送成功";
    public static final String ERROR = "非法的电子邮箱地址";
    public static final String MSG = "亲爱的用户：\n" +
            "\n" +
            " \n" +
            "您好！感谢您使用莞工校招助手，您的账号正在进行邮箱验证，本次请求的验证码为：\n" +
            "\n" +
            "【%s】(为了保障您帐号的安全性，请在5分钟内完成验证。)\n" +
            "\n" +
            " \n" +
            "认证中心服务\n" +
            "\n" +
            "%s";
}

添加邮箱pom依赖：

<!--邮箱验证码服务-->
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-email -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-email</artifactId>
    <version>1.5</version>
</dependency>

申请一个163邮箱，并开启代理服务，注意妥善保存授权密码：

创建验证控制器VerifyController用于发送验证码、鉴别验证码、销毁验证码：

package com.gateway.controller.verifycode;

import cn.hutool.core.convert.Convert;
import com.gateway.component.EmailProperties;
import com.gateway.constant.EmailConstant;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;

为什么设计邮箱验证码

首先是为了机器验证，防止恶意脚本；其次是因为防水墙前后端二次检验有点复杂，笔者还是想从简单的事情做起，循序渐进；最后是第三方认证的问题，本来是想做微信或者QQ第三方认证登录的，后来发现经费不足，所以采用传统邮箱登录方法，验证码刚好相辅相成。

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集

(20200916 Solved)docker-compose up创建容器自动退出

问题描述如题，创建容器后自动退出了。并且docker start container无效解决方案原因是缺失了控制终端的配置，需要在docker-compose.yml中增加tty:true ，有时候这样也不行，需要再增加一个command:/bin/bash，命令不一定是这个，需要是一个不会退出的命令，然后用-d后台启动容器。Referencesdocker-compose启动容器后自动退出...
