微服务系列文章之 Springboot+Vue实现登录注册

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

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）

1 2 3 4 5 6 7 8 9

package springbootmybatis.pojo; import lombok.Data; @Data public class User {     private String account;     private String password; }

UserMapper.java

1 2 3 4 5 6 7 8 9 10

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<?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

1 2 3 4 5 6 7 8 9 10 11 12

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

1 2 3 4

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。

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

安装VUE

1	npm i -g vue-cli

初始化包结构

1	vue init webpack project

启动项目

1 2 3 4 5 6

# 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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<template>   <div id="app">     <router-view/>   </div> </template> <script> export default {   name: 'App' } </script> <style> </style>

welcome.vue

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48

<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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

// 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 axios from 'axios' import VueAxios from 'vue-axios' Vue.use(VueAxios, axios) Vue.use(ElementUI) Vue.config.productionTip = false /* eslint-disable no-new */ new Vue({   el: '#app',   router,   components: {App},   template: '<App/>' })

router/index.js

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import Vue from 'vue' import Router from 'vue-router' import welcome from '@/components/welcome' Vue.use(Router) export default new Router({   routes: [     {       path: '/',       name: 'welcome',       component: welcome     }   ] })
