springboot整合vue-element-template 实现登录

首先需要安装好SpringBoot和Vue，然后按照以下步骤整合vue-element-template实现登录功能：

1. 在vue-element-template中的src/api目录下新建一个user.js文件，用于定义登录接口：

import request from '@/utils/request'

export function login(username, password) {
  return request({
    url: '/login',
    method: 'post',
    data: {
      username,
      password
    }
  })
}

2. 在vue-element-template中的src/views/login目录下新建一个index.vue文件，用于实现登录页面：

<template>
  <div class="login-container">
    <div class="login-box">
      <h2>登录</h2>
      <el-form ref="form" :model="form" :rules="rules" label-position="left" label-width="80px" class="login-form">
        <el-form-item label="用户名" prop="username">
          <el-input v-model="form.username"></el-input>
        </el-form-item>
        <el-form-item label="密码" prop="password">
          <el-input type="password" v-model="form.password"></el-input>
        </el-form-item>
        <el-form-item>
          <el-button type="primary" @click="submitForm">登录</el-button>
        </el-form-item>
      </el-form>
    </div>
  </div>
</template>

<script>
import { login } from '@/api/user'

export default {
  name: 'Login',
  data() {
    return {
      form: {
        username: '',
        password: ''
      },
      rules: {
        username: [{ required: true, message: '请输入用户名', trigger: 'blur' }],
        password: [{ required: true, message: '请输入密码', trigger: 'blur' }]
      }
    }
  },
  methods: {
    submitForm() {
      this.$refs.form.validate(valid => {
        if (valid) {
          login(this.form.username, this.form.password).then(response => {
            if (response.data.code === 0) {
              this.$message.success('登录成功')
              this.$router.push('/')
            } else {
              this.$message.error(response.data.msg)
            }
          }).catch(error => {
            console.log(error)
          })
        } else {
          return false
        }
      })
    }
  }
}
</script>

<style scoped>
.login-container {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}

.login-box {
  width: 400px;
  height: 400px;
  background-color: #fff;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
  border-radius: 4px;
  padding: 20px;
}

.login-form {
  margin-top: 20px;
}
</style>

3. 在SpringBoot中的controller中定义/login接口，用于处理登录请求：

@RestController
public class UserController {
    
    @PostMapping("/login")
    public Result login(@RequestBody User user) {
        // 验证用户名和密码
        if ("admin".equals(user.getUsername()) && "123456".equals(user.getPassword())) {
            return Result.ok();
        } else {
            return Result.error("用户名或密码错误");
        }
    }
    
}

4. 在SpringBoot中的application.properties中配置跨域访问：

# 允许跨域访问
spring.mvc.cors.allow-credentials=true
spring.mvc.cors.allowed-origins=*
spring.mvc.cors.allowed-methods=GET,POST,PUT,DELETE,OPTIONS
spring.mvc.cors.allowed-headers=*

这样就实现了SpringBoot和vue-element-template的整合，实现了登录功能。
