本文介绍了spring-boot结合shrio实现jwt的方法，分享给大家，具体如下：
关于验证大致分为两个方面：
- 用户登录时的验证；
- 用户登录后每次访问时的权限认证
主要解决方法：使用自定义的shiro filter
项目搭建：
这是一个spring-boot 的web项目，不了解spring-boot的项目搭建，请google。

划重点！！自定义了一个filter

自定义shrio filter
执行顺序：prehandle -> dofilterinternal -> executelogin -> onloginsuccess
主要判断是不是登录请求的是 dofilterinternal

处理jwt异常
这是个坑，因为是在filter内发生的异常，@exceptionhandler是截获不到的。

关于权限等授权信息，可以直接放到redis中实现缓存。我认为也是不错的。
源码奉上：githup-shiro分支 ：温馨提示：平时测试代码可能比较乱。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
