1.添加QRcode页面代码

<template>
      <div class="register">
        <el-form ref="registerForm" :model="registerForm" :rules="registerRules" class="register-form">
          <h3 class="title">花神引后台管理系统</h3>
          <el-form-item>
            <div class="text" >使用QQ/支付宝/钉钉扫码快速登录</div>
            <div class="QRcode">

    <style rel="stylesheet/scss" lang="scss">
    .text{
      font-size: 12px;
      text-align: center;
    
    }
    
    .register {
      display: flex;
      justify-content: center;
      align-items: center;
      height: 100%;
      background-image: url("../assets/images/login-background.jpg");
      background-size: cover;
    }
    .title {
      margin: 0px auto 30px auto;
      text-align: center;
      color: #707070;
    }
    
    .register-form {
      border-radius: 6px;
      background: rgba(255, 255, 255, .3);
      width: 400px;
      padding: 25px 25px 5px 25px;
      .el-input {
        height: 38px;
        input {
          height: 38px;
        }
      }
      .input-icon {
        height: 39px;
        width: 14px;
        margin-left: 2px;
      }
    }
    .register-tip {
      font-size: 13px;
      text-align: center;
      color: #bfbfbf;
    }
    .register-code {
      width: 33%;
      height: 38px;
      float: right;
      img {
        cursor: pointer;
        vertical-align: middle;
      }
    }
    .el-register-footer {
      height: 40px;
      line-height: 40px;
      position: fixed;
      bottom: 0;
      width: 100%;
      text-align: center;
      color: #fff;
      font-family: Arial;
      font-size: 12px;

      }
      .Sina{
        color: #D81E06;
      }
    }
    </style>

2.在登录页面加页面链接

<div  style="float: right;line-height: 30px" >
    
              <h5><router-link class="link-type" :to="'/QRcode'" >二维码登录</router-link></h5>
            </div>

3.在过滤器添加（framework/config/SecurityConfig.java）

.antMatchers("/login", "/register", "/captchaImage","/QRcode","Dingtalk").anonymous()
                    .antMatchers("/login", "/captcha/get", "/captcha/check","/QRcode","Dingtalk").permitAll()

4.路由（/src/router/index.js）

{
        path: '/QRcode',
        component: () => import('@/views/QRcode'),
        hidden: true
      },

5.白名单(/src/permission.js)  
/\*白名单，添加后可不必登录访问\*/

const whiteList = ['/login', '/auth-redirect', '/bind', '/register','/QRcode']

6.后台代码注释掉注解

@PreAuthorize

@DataScope

7.修改spring security配置SecurityConfig.java
