Springboot安全框架整合SpringSecurity实现方式

目录

• 1.工业级安全框架介绍
• 2.建议搭建Spring Security环境       
  • 2.1在pom.xml中添加相关依赖
  • 2.2创建Handler类 
  • 2.3创建简单的html和配置相关thymeleaf的路径
  • 2.4最后再加个启动类，那么我们的整合测试就完成勒
  • 2.5成果展示 用户名默认user，密码则随机生成的这串数字
• 3.进阶版使用      
  • 3.1用户名和密码自定义
  • 3.2在config包下创建Encoder进行密码的校验和转码操作
  • 3.3赋予账号角色权限
