SpringBoot+Shiro+JWT权限管理

Shiro

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。

使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。

三个核心组件：Subject, SecurityManager 和 Realms.

Subject代表了当前用户的安全操作,即“当前操作用户”。
SecurityManager：它是Shiro框架的核心，典型的Facade模式，Shiro通过SecurityManager来管理内部组件实例，并通过它来提供安全管理的各种服务。
Realm： Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说，当对用户执行认证（登录）和授权（访问控制）验证时，Shiro会从应用配置的Realm中查找用户及其权限信息。

JWT

JSON Web Token（JWT）是目前最流行的跨域身份验证解决方案

JSON Web令牌是一种开放的行业标准 RFC 7519方法，用于在双方之间安全地表示声明。

JWT 数据结构

JWT有三部分组成：Header:头部，Payload:负载，Signature:签名
