整合vue elementui springboot mybatisplus前后端分离的 简单增加功能 删改查未实现

sk古月2023-09-24 9:38

涉及知识点

1.springboot项目启动创建 配置yml文件

2.mybatisplus的使用

3.vue的vite文件配置

4.vue springboot 前后端数据交互

后端

1.建立项目的配置文件

src/main/resources/application.yml

java 复制代码 
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      username: root
      password:
      url: jdbc:mysql:/dbwx
      driver-class-name: com.mysql.cj.jdbc.Driver
2.建立项目

pom.xml

XML 复制代码 
<?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">

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>
3.建立数据库表
sql 复制代码 
CREATE DATABASE `dbwx` DEFAULT CHARACTER SET utf8mb3;

use dbwx;

CREATE TABLE `t_user` (
  `id` bigint NOT NULL,
  `account` varchar(50) DEFAULT NULL,
  `passwd` varchar(32) DEFAULT NULL,
  `name` varchar(50) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `account` (`account`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3;
4.建立实体类

cn.webrx.pojo.User

java 复制代码 
package cn.webrx.pojo;

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

import java.time.LocalDate;
@Data @TableName("t_user")
public class User {
    @TableId
    private Long id;
    private String account;
    @TableField("passwd")
    private String password;
    private String name;
    private LocalDate birthday;
}
5.建立项目入口程序App

cn.webrx.App

java 复制代码 
package cn.webrx;

import cn.webrx.mapper.DbMapper;
import cn.webrx.pojo.User;
import cn.webrx.mapper.UserMapper;
import cn.webrx.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
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;

import javax.annotation.Resource;
import java.util.List;
import java.util.Set;

@SpringBootApplication
@RestController
public class App {
    @Resource
    DbMapper dm;

    @Resource
    UserService us;

    @GetMapping("/dbs")
    public Set<String> dbs(){
        return dm.dbs();
    }

    @GetMapping("/list")
    public List<User> list(){
        return us.list();
    }



    @GetMapping("/users")
    public cn.webrx.beans.User getUser() {
        return new cn.webrx.beans.User(199, "李四六");
    }


    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}
6.建立sevices
java 复制代码 
//cn.webrx.mapper
@Mapper
public interface UserMapper extends BaseMapper<User> {}

//cn.webrx.service
public interface UserService extends IService<User> {}

//cn.webrx.service
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
}

axios拦截器封装

/src/lib/http.js

javascript 复制代码 
//http.js  request.js

//1 导入
import axios from 'axios'

//2 配置
axios.defaults.baseURL = '/api'
axios.defaults.timeout = 5000

//3 请求拦截器 - 添加请求拦截器
axios.interceptors.request.use(config => {
    // 在发送请求之前做些什么
    config.headers.token = '11111111111111111111'
    return config;
}, function (error) {
    // 对请求错误做些什么
    return Promise.reject(error);
});

//4 添加响应拦截器
axios.interceptors.response.use(response => {
    // 对响应数据做点什么
    return response.data;
}, function (error) {
    // 对响应错误做点什么
    ElMessage({
        type: 'error',
        message: '响应失败'
    })
    return Promise.reject(error)
})

export default axios

./src/lib/user.js

javascript 复制代码 
import axios from './http'
//添加
export const addUser = async function (url, d, callback) {
     const data = await axios.post(url,d)
     await callback(data)
}

//删除

//显示 url,data

//修改
export const getUsers = async function (url, params, callback) {
     const data = await axios.get(url,params)
     await callback(data)
}

APP.vue

javascript 复制代码 
<script setup>
import {getUsers,addUser} from '@/lib/user'
import {ref} from 'vue'
import {ElMessage} from "element-plus";
const msg = ref({id: 0, name: ''})
function abc(){
  getUsers('/users',{},d=>{
    ElMessage(d.name)

    console.log(d)
  })
}
const form = ref({
  name: '李四',
  account: 'admin',
  password: '123',
  birthday: '2013-10-25'
})

function add() {
  addUser("/addUser", form.value, data => {
    if (data.code === 200) {
      ElMessage({type: 'success', message: data.msg})
    } else {
      ElMessage({type: 'error', message: data.msg})
    }
  })
}
</script>

<template>
  <h3>{{ msg.name }}</h3>
  <el-button @click="abc">get</el-button>

  <!-- 添加用户 -->
  <el-row>
    <el-col :span="20" :offset="2">
      <el-form :model="form" label-width="120px">
        <el-form-item label="姓名">
          <el-input v-model="form.name"/>
        </el-form-item>

        <el-form-item label="账号">
          <el-input type="text" v-model="form.account"/>
        </el-form-item>

        <el-form-item label="密码">
          <el-input type="password" v-model="form.password"/>
        </el-form-item>
        <el-form-item label="出生日期">
          <el-col :span="11">
            <el-date-picker
                v-model="form.birthday"
                type="date"
                placeholder="请选择出生日期"
                style="width: 100%"/>
          </el-col>
        </el-form-item>

        <el-form-item>
          <el-button type="primary" @click="add">添加新用户</el-button>
          <el-button>取消</el-button>
        </el-form-item>
      </el-form>
    </el-col>
  </el-row>
</template>

<style scoped>
