springboot+vue前后端分离项目-项目搭建4

1.修改vue布局，app.vue为入口，只引入路由，路由控制页面显示

改造后app.vue

 新增layout.vue

 修改/router/index.js，默认访问路径 / 对应layout.vue，layout里的路由是嵌套路由，/home匹配到HomeView.vue

 

 新增vue/src/views/LoginView.vue

 效果

 

 

 

 2.优化登录页面LoginView.vue

<template>
  <div style="width: 100%; height: 100vh; background-color: darkslateblue; overflow: hidden">
    <div style="width: 400px; margin: 150px auto">
      <div style="color: #cccccc; font-size: 30px; text-align: center; padding: 30px 0">欢迎登录</div>
      <el-form label-position="right" :model="form" size="normal">
        <el-form-item >
          <el-input :prefix-icon="Avatar" v-model="form.username"/>
        </el-form-item>
        <el-form-item >
          <el-input :prefix-icon="Lock" v-model="form.password" show-password/>
        </el-form-item>
        <el-form-item>
          <el-button style="width: 100%;" type="primary" @click="login">登 录</el-button>
        </el-form-item>
      </el-form>
    </div>
  </div>
</template>

<script>
import request from "@/utils/request";

export default {
  name: "LoginView",
  data(){
    return {
      form: {}
    }
  },
  methods: {
    login() {
      request.post("/user/login", this.form).then(res => {
        console.log(res)
        if (res.code === '0') {
          this.$message({
            type: "success",
            message: "登录成功"
          })
          this.$router.push("/") //登陆成功后跳转到主页
        } else {
          this.$message({
            type: "error",
            message: "res.msg"
          })
        }
      });
    }
  }
}
</script>

<script setup>
import { Avatar,Lock } from '@element-plus/icons-vue'
</script>

<style scoped>

</style>

效果：

 3.后台增加登录处理，UserController

    @PostMapping("/login")
    public Result<?> login(@RequestBody User user){
        User res = userMapper.selectOne(Wrappers.<User>lambdaQuery().eq(User::getUsername, user.getUsername()).eq(User::getPassword, user.getPassword()));
        if(res == null){
            return Result.error("-1", "用户名或密码错误");
        }
        return Result.success();
    }

效果：

 

 4.增加退出系统功能，添加按钮，路由转到/login

 5.新增注册页面，vue/src/views/Register.vue，增加rules校验，注册页面编写后测试，validate位置报错，排查发现el-form属性里必须要有ref="form"，然后才能支持this.$refs.form.validate

<template>
  <div style="width: 100%; height: 100vh; background-color: darkslateblue; overflow: hidden">
    <div style="width: 400px; margin: 150px auto">
      <div style="color: #cccccc; font-size: 30px; text-align: center; padding: 30px 0">欢迎登录</div>
      <el-form :model="form" size="normal" :rules="rules" ref="form">
        <el-form-item prop="username">
          <el-input :prefix-icon="Avatar" v-model="form.username"/>
        </el-form-item>
        <el-form-item prop="password">
          <el-input :prefix-icon="Lock" v-model="form.password" show-password/>
        </el-form-item>
        <el-form-item prop="confirm">
          <el-input :prefix-icon="Lock" v-model="form.confirm" show-password/>
        </el-form-item>
        <el-form-item>
          <el-button style="width: 100%;" type="primary" @click="register">注 册</el-button>
        </el-form-item>
      </el-form>
    </div>
  </div>
</template>

<script>
import request from "@/utils/request";

export default {
  name: "Register",
  data(){
    return {
      form: {},
      rules: {
        username: [
          { required: true, message: '请输入用户名', trigger: 'blur' }
        ],
        password: [
          { required: true, message: '请输入密码', trigger: 'blur' }
        ],
        confirm: [
          { required: true, message: '请确认密码', trigger: 'blur' }
        ]
      }
    }
  },
  methods: {
    register() {
      if(this.form.password !== this.form.confirm){
        this.$message({
          type: "error",
          message: "2次密码输入不一致"
        })
        return
      }
      this.$refs.form.validate((valid) => {
        if(valid){
          request.post("/user/register", this.form).then(res => {
            console.log(res)
            if (res.code === '0') {
              this.$message({
                type: "success",
                message: "注册成功"
              })
              this.$router.push("/login") //注册成功后跳转到主页
            } else {
              this.$message({
                type: "error",
                message: res.msg
              })
            }
          })
        } else {
          this.$message({
            type: "error",
            message: "输入信息有误"
          })
        }
      })
    }
  }
}
</script>

<script setup>
import { Avatar,Lock } from '@element-plus/icons-vue'
</script>

<style scoped>

</style>

6.后台增加注册处理

    @PostMapping("/register")
    public Result<?> register(@RequestBody User user){
        User res = userMapper.selectOne(Wrappers.<User>lambdaQuery().eq(User::getUsername, user.getUsername()));
        if(res != null){
            return Result.error("-1", "用户名重复");
        }
        if(user.getPassword() == null){
            user.setPassword("123456");
        }
        userMapper.insert(user);
        return Result.success();
    }

7.调整路由

 效果：

 8.优化新增和编辑的form显示，优化前label右边不对齐，优化后所有label都对齐，只需要增加label-width="auto"
