• 02_SpringSecurity学习之多种配置共存

    文章目录

    前言

      本人菜鸟一枚，这篇文章算是我学习 Spring Security 的记录吧.

    环境

    • Intellij IDEA 2022.2
    • Spring Boot 2.7.2
      • Spring Security 5.7.2

    HttpSecurity多环境配置

      这个可以参考官方的文档1，我的配置如下：

      然后就既可以通过表单登录，也可以通过api接口登录。表单登录如下图所示：

    表单登录

      api接口登录如下所示：

    ### login rest 登录测试
POST http://localhost:8080/api/login
Content-Type: application/json

{
  "username": "admin",
  "password": "password"
}
