</configuration>
</plugin>
</plugins>
</build>
</project>
2.2接着创建springboot的main方法类,因为是集成dubbo框架,所以记得添加注解
@EnableDubboConfiguration
2.3 继续创建resources文件下的主配置文件,因为要采用maven生成映射文件mapper.所以同时创建一个GeneratorMapper.xml的配置文件,其生成映射文件的依赖包已经在pom文件<build>标签中声明过了.
application.properties内容如下:
# WEB服务端口
server.port=9200
# dubbo配置
spring.dubbo.appname=14-springboot-all-dubbo-provider
spring.dubbo.registry=zookeeper://192.168.174.129:2181
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.174.129:3306/springdb?useUnicode=true&characterEncoding=utf8&useSSL=false
GeneratorMapper.xml的内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 指定连接数据库的JDBC驱动包所在位置,指定到你本机的完整路径 -->
<classPathEntry location="E:/JAVA/demo/repository/mysql/mysql-connector-java/5.1.43/mysql-connector-java-5.1.43.jar"/>
<!-- 配置table表信息内容体,targetRuntime指定采用MyBatis3的版本 -->
<context id="tables" targetRuntime="MyBatis3">
<!-- 抑制生成注释,由于生成的注释都是英文的,可以不让它生成 -->
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 配置数据库连接信息 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://192.168.174.129:3306/springdb"
userId="root"
password="123456">
</jdbcConnection>
<!-- 生成model类,targetPackage指定model类的包名, targetProject指定生成的model放在eclipse的哪个工程下面-->
<javaModelGenerator targetPackage="com.kinglong.springboot.model" targetProject="src/main/java">
<property name="enableSubPackages" value="false" />
<property name="trimStrings" value="false" />
</javaModelGenerator>
<!-- 生成MyBatis的Mapper.xml文件,targetPackage指定mapper.xml文件的包名, targetProject指定生成的mapper.xml放在eclipse的哪个工程下面 -->
<sqlMapGenerator targetPackage="com.kinglong.springboot.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="false" />
</sqlMapGenerator>
<!-- 生成MyBatis的Mapper接口类文件,targetPackage指定Mapper接口类的包名, targetProject指定生成的Mapper接口放在eclipse的哪个工程下面 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.kinglong.springboot.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="false" />
</javaClientGenerator>
<!-- 数据库表名及对应的Java模型类名 -->
<table tableName="u_user"
domainObjectName="User"
enableCountByExample="false"
enableUpdateByExample="false"
enableDeleteByExample="false"
enableSelectByExample="false"
selectByExampleQueryId="false"/>
</context>
</generatorConfiguration>
一切准备就绪之后,就可以生成mapper映射文件了
点击生成之后如下提示:
因为model类在interface中已经创建,所以在这里创建的要删除他.在这里用不到.
因为使用的是注解开发,所以在映射文件中要添加注解@Mapper如果在此处不添加注解,就需要在main方法类Application中添加了,使用起来会繁琐一点.
2.4创建业务实现类UserServiceImpl
具体如下:
package com.kinglong.springboot.service.impl;
import com.kinglong.springboot.model.User;
import com.kinglong.springboot.service.UserService;
import org.springframework.stereotype.Service;
import java.util.List;
import java.util.Map;
//spring的service注解
@Service
//dubbo的service注解
@com.alibaba.dubbo.config.annotation.Service
public class UserServiceImpl implements UserService{
@Override
public User getUser(Integer id) {
return null;
}
@Override
public int addUser(User user) {
return 0;
}
@Override
public int updateUser(User user) {
return 0;
}
@Override
public int deleteUser(Integer id) {
return 0;
}
@Override
public List<User> getUserByPage(Map<String, Object> paramMap) {
return null;
}
@Override
public int getUserByTotal() {
return 0;
}
}
敲黑板了!!!!重点来了!注意一下,需要在实现类上添加两个@Service注解,一个是dubbo框架的,一个是spring框架的.因为dubbo需要暴露服务,而同时spring容器需要加载管理它,所以添加两个即可,如果不添加,则同样需要在
main方法类Application中添加了,使用起来会繁琐一点.
3.创建消费者consumer
3.1检查pom文件依赖,添加所需依赖,具体如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<groupId>com.kinglong.springboot</groupId>
<artifactId>springboot-dubbo-consumer</artifactId>
<version>1.0.0</version>
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<!--springboot起步依赖-->

</dependency>
<!--springboot集成dubbo的依赖-->

</dependency>
<!--zookeeper客户端jar依赖-->
<dependency>

</dependency>
<!--dubbo接口项目依赖-->
<dependency>
<groupId>com.kinglong.springboot</groupId>
<artifactId>springboot-dubbo-interface</artifactId>
<version>1.0.0</version>
</dependency>
<!--springboot集成Thymeleaf依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>net.sourceforge.nekohtml</groupId>
<artifactId>nekohtml</artifactId>

<dependency>
<groupId>org.unbescape</groupId>
<artifactId>unbescape</artifactId>
<version>1.1.5.RELEASE</version>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
又一个重点来了!由于springboot推荐使用的前端展示页面为thymeleaf,所以这里添加了thymeleaf的依赖包
3.2 依旧接着创建springboot的main方法类,因为是集成dubbo框架,所以记得添加注解@EnableDubboConfiguration
3.3继续创建resources文件中的主配置文件以及前端展示页面user.html
application.properties内容如下:
# WEB服务端口
server.port=9100
# dubbo配置
spring.dubbo.appname=14-springboot-all-dubbo-provider
spring.dubbo.registry=zookeeper://192.168.174.129:2181
#开发阶段,建议关闭thymeleaf的缓存
spring.thymeleaf.cache=false
#使用遗留的html5以去掉对html标签的校验
spring.thymeleaf.mode=LEGACYHTML5
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.html
user.html内容如下:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Spring boot集成 Thymeleaf</title>
</head>
<body>
<p th:each="user : ${userList}">
<span th:text="${user.id}"></span>
<span th:text="${user.nick}"></span>
<span th:text="${user.phone}"></span>
<span th:text="${user.email}"></span>
<span th:text="${user.address}"></span>
</p>
</body>
</html>
3.4创建controller文件,内容如下:
package com.kinglong.springboot.controller;
import com.alibaba.dubbo.config.annotation.Reference;
import com.kinglong.springboot.model.User;
import com.kinglong.springboot.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import java.util.List;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
@Controller
public class UserController {
@Reference
private UserService userService;
@RequestMapping("/all/index")
public String index (Model model,
@RequestParam(value="currentPage", required = false) Integer currentPage) {
int pageSize = 10;
if (null == currentPage) {
currentPage = 1;
}
int totalRow = userService.getUserByTotal();
int totalPage = totalRow / pageSize;
int left = totalRow % pageSize;
if (left > 0) {
totalPage = totalPage + 1;
}
int startRow = (currentPage-1) * pageSize;
Map<String, Object> paramMap = new ConcurrentHashMap<>();
paramMap.put("startRow", startRow);
paramMap.put("pageSize", pageSize);
List<User> userList = userService.getUserByPage(paramMap);
model.addAttribute("userList", userList);
return "user";
}
}
最后,起服测试,我随意填写了个测试数据,效果如下.
总结:这是最基本的springboot集成各框架运行的Demo,熟练应运他之后相信springboot框架也会很熟练的,其实,springboot框架只是在spring框架的基础上再次做了集成,所以,如果spring框架如果用的熟练的话,相信一定会很快地掌握的.
