一、springBoot

创建springBoot项目
分为三个包，分别为controller，service， dao以及resource目录下的xml文件。
UserController.java

package springbootmybatis.controller;

import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import springbootmybatis.pojo.User;
import springbootmybatis.service.UserService;

import javax.annotation.Resource;


@RestController
public class UserController {
    @Resource
    UserService userService;

    @PostMapping("/register/")
    @CrossOrigin("*")
    String register(@RequestBody User user) {
        System.out.println("有人请求注册！");
        int res = userService.register(user.getAccount(), user.getPassword());
        if(res==1) {
            return "注册成功";
        } else {
            return "注册失败";
        }
    }

    @PostMapping("/login/")
    @CrossOrigin("*")
    String login(@RequestBody User user) {
        int res = userService.login(user.getAccount(), user.getPassword());
        if(res==1) {
            return "登录成功";
        } else {
            return "登录失败";
        }
    }
}

UserService.java

package springbootmybatis.service;

import org.springframework.stereotype.Service;
import springbootmybatis.dao.UserMapper;

import javax.annotation.Resource;

@Service
public class UserService {
    @Resource
    UserMapper userMapper;

    public int register(String account, String password) {
        return userMapper.register(account, password);
    }

    public int login(String account, String password) {
        return userMapper.login(account, password);
    }
}

User.java （我安装了lombok插件）

package springbootmybatis.pojo;

import lombok.Data;

@Data
public class User {
    private String account;
    private String password;
}

UserMapper.java

package springbootmybatis.dao;

import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface UserMapper {
    int register(String account, String password);

    int login(String account, String password);
}

UserMapper.xml

<?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="springbootmybatis.dao.UserMapper">

    <insert id="register">
       insert into User (account, password) values (#{account}, #{password});
    </insert>

    <select id="login" resultType="Integer">
        select count(*) from User where account=#{account} and password=#{password};
    </select>
</mapper>

主干配置
application.yaml

server.port: 8000
spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/community?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
    driver-class-name: com.mysql.cj.jdbc.Driver
mybatis:
    type-aliases-package: springbootmybatis.pojo
    mapper-locations: classpath:mybatis/mapper/*.xml
    configuration:
      map-underscore-to-camel-case: true

数据库需要建相应得到表

CREATE TABLE `user` (
  `account` varchar(255) COLLATE utf8_bin DEFAULT NULL,
  `password` varchar(255) COLLATE utf8_bin DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

二、创建VUE项目
安装node，npm，配置环境变量。
配置cnpm仓库，下载的时候可以快一些。

npm i -g cnpm --registry=https://registry.npm.taobao.org

安装VUE

npm i -g vue-cli

初始化包结构

vue init webpack project

启动项目

# 进入项目目录
cd vue-01
# 编译
npm install
# 启动
npm run dev

修改项目文件，按照如下结构

APP.vue

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

<style>

</style>

welcome.vue

<template>
  <div>
    <el-input v-model="account" placeholder="请输入帐号"></el-input>
    <el-input v-model="password" placeholder="请输入密码" show-password></el-input>
    <el-button type="primary" @click="login">登录</el-button>
    <el-button type="primary" @click="register">注册</el-button>
  </div>
</template>

<script>
export default {
  name: 'welcome',
  data () {
    return {
      account: '',
      password: ''
    }
  },
  methods: {
    register: function () {
      this.axios.post('/api/register/', {
        account: this.account,
        password: this.password
      }).then(function (response) {
        console.log(response);
      }).catch(function (error) {
        console.log(error);
      });
      // this.$router.push({path:'/registry'});
    },
    login: function () {
      this.axios.post('/api/login/', {
        account: this.account,
        password: this.password
      }).then(function () {
        alert('登录成功');
      }).catch(function (e) {
        alert(e)
      })
      // this.$router.push({path: '/board'});
    }
  }
}
</script>

<style scoped>

</style>

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'
