• （微服务多模块）Springboot+Security+Redis+JWT 仅需一招

    小编在开发阶段发现，在现在众多文章中的教程里，虽然有许许多多的Springboot+Security+Redis+JWT，但是那些教程基本的运行环境都在单个项目单个模块中进行开发和测试的，这使得小编在实际的开发过程中，不能Ctrl+C and Ctrl+V直接完全解决这个登录认证的事情。故有这篇文章。

    5.9 LogOutSuccessHandler（LogoutSuccessHandler）

    5.10 NothingAccessDeniedHandler（AccessDeniedHandler）

    6.测试

    1.项目结构

    涉及的模块有common（Redis配置文件、Redis工具、Token工具、返回信息的工具；即如下文件RedisConfig、RedisUtil、TokenUtil、ResponseUtil）、model（user的实体类）、service（主要利用MySQL查询用户数据）、spring_security（多个配置文件，配置security的）。

    下面小编将全部一一介绍并且源码展示出来。

      6.测试
       

       
 
      这里是使用postman工具进行测试的，在这里之前已经在数据库有用户名跟密码都为user的数据，并且密码已是加密形式。
       

       

      1.首次访问index，如下图
       

       

      2.访问/login，并且提供相关参数，如下图：
       

       

      这时，redis数据库就有了用户名为 user的数据 
       

       

      3.在返回Headers信息中找到token，复制除了Bearer+空格以外的东西，如下图的蓝色底token
       

       

      4.将请求方式改成Get，在Authorization的Type中，选择Bearer Token，粘贴上刚才的Token，点击Send发送
       

       

       5.就会显示可以正常访问index页面了
       

       

      6.退出则为/logout ，带上参数username即可，请求方式为POST。
