搭建SpringBoot+Vue 项目 完整流程
创建完成后,到IDEA,查看后端项目目录,看是否创建成功;若成功则继续下面的步骤;在这一步有个插曲,在IDEA运行出现了这样的错误:解决方法如下:看看自己的项目里面是否有node_modules文件夹,(1)如果没有就尝试执行npm install,这是因为缺少依赖包。(2)如果有就将这个node_modules文件夹删掉,重新执行npm install,等待安装完之后,再次运行“npm run
·
一、创建后端 SpringBoot 项目
- 创建过程 略
- 创建好后,删除多余文件(可参考后续目录格式)
- 修改 Maven 相应的路径配置
- 编写 yml 文件,编写端口、数据库连接等配置
- 测试一下后端
编写测试代码如下:
运行结果如下:
ok ! 后端的初步搭建告一段落
二、Vue 创建前端项目
- 这里需要说明的是:前端项目将他放在了后端项目的一个文件夹中,所以创建时,需要切换目录到相应位置。
- win+R --> cmd,切换目录到相应位置,创建前端项目
vue init webpack xxxxx
//其中xxxxx为Vue的项目名称
创建完成后,到IDEA,查看后端项目目录,看是否创建成功;若成功则继续下面的步骤;
- 切换到vue目录下,然后 npm run dev
在这一步有个插曲,在IDEA运行出现了这样的错误:
解决方法如下:
看看自己的项目里面是否有node_modules文件夹,
(1)如果没有就尝试执行npm install,这是因为缺少依赖包。
(2)如果有就将这个node_modules文件夹删掉,重新执行npm install,等待安装完之后,再次运行“npm run dev”
按第二步执行完后,运行成功:
前端的搭建就 OK 了 !
三、SpringBoot 集成 MyBatis
- 创建数据库
- 按下面的目录,创建相关的文件
- 编写下面的代码,并进行测试
package com.zjw.management;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class ManagementApplication {
public static void main(String[] args) {
SpringApplication.run(ManagementApplication.class, args);
}
}
package com.zjw.management.entity;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
@Data
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String username;
private String password;
private String nickname;
private String email;
private String phone;
private String address;
private Date createTime;
private String avatarUrl;
private String role;
}
package com.zjw.management.controller;
import com.zjw.management.entity.User;
import com.zjw.management.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController
public class UserController {
@Autowired
private UserMapper userMapper;
@GetMapping("/")
public List<User> index(){
List<User> all = userMapper.findAll();
return all;
}
}
package com.zjw.management.mapper;
import com.zjw.management.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import java.util.List;
@Mapper
public interface UserMapper {
@Select("SELECT * from sys_user")
List<User> findAll();
}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zjw.management.mapper.UserMapper">
</mapper>
测试结果如下:
到这里,后端项目和数据库的连接已经成功 !
四、前后端联调
- 编写后端代码,实现 “findAll” 和 “findPage” 方法,并对接口进行测试;
package com.zjw.management.mapper;
import com.zjw.management.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import java.util.List;
@Mapper
public interface UserMapper {
@Select("SELECT * from sys_user")
List<User> findAll();
@Select("select * from sys_user where username like #{username} limit #{pageNum}, #{pageSize}")
List<User> selectPage(Integer pageNum, Integer pageSize, String username);
@Select("select count(*) from sys_user where username like concat('%', #{username}, '%') ")
Integer selectTotal(String username);
}
package com.zjw.management.controller;
import com.zjw.management.entity.User;
import com.zjw.management.mapper.UserMapper;
import com.zjw.management.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserMapper userMapper;
//查询所有
@GetMapping
public List<User> findAll(){
List<User> all = userMapper.findAll();
return all;
}
//分页查询
//接口路径:/user/page?pageNum=1&pageSize=3&username
@GetMapping("/page")
public Map<String, Object> findPage(@RequestParam Integer pageNum,
@RequestParam Integer pageSize,
@RequestParam String username){
pageNum = (pageNum - 1) * pageSize;
username = "%" + username + "%";
List<User> data = userMapper.selectPage(pageNum, pageSize, username);
Integer total = userMapper.selectTotal(username);
Map<String, Object> res = new HashMap<>();
res.put("data", data);
res.put("total", total);
return res;
}
}
测试一下:
- 编写前端测试页面 “Home.vue” ,并配置相关路由,进行测试;
修改或添加以下的文件:
(1) gloable.css
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.ml-5 {
margin-left: 5px;
}
.mr-5 {
margin-right: 5px;
}
.pd-10 {
padding: 10px 0;
}
(2) router/index.js
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Home from '@/views/Home'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/Home',
name: 'Home',
component: Home
}
]
})
(3) views/Home.vue

</template>
<script>
export default {

<style>
#app {
min-height: 100vh;
}
</style>
(5) main.js
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import './assets/gloable.css'
Vue.config.productionTip = false
Vue.use(ElementUI, { size: "mini" });
/* eslint-disable no-new */
new Vue({
router,
render: h => h(App)
}).$mount('#app')
- 解决跨域问题,并进行前后端联调测试;
在后端 config 目录下,编写 CorsConfig.java 解决跨域问题
package com.zjw.management.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
@Configuration
public class CorsConfig {
// 当前跨域请求最大有效时长。这里默认1天
private static final long MAX_AGE = 24 * 60 * 60;
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("http://localhost:8080"); // 1 设置访问源地址
corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
corsConfiguration.setMaxAge(MAX_AGE);
source.registerCorsConfiguration("/**", corsConfiguration); // 4 对接口配置跨域设置
return new CorsFilter(source);
}
}
前后端联调,在前端页面进行测试,结果如下:
到这里,前端可以成功地将数据库的数据展示到页面上,联调成功,框架搭建结束。
