.......................................................................................... 58 SUBJECT ................................................................................................ 可以看到：应用代码直接交互的对象是Subject，也就是说Shiro的对外API核心就是Subject； 其每个 API 的含义： Subject：主体，代表了当前“用户”，这个用户不一定是一个具体的人，与当前应用交互 的任何东西都是 Subject，如网络爬虫，机器人等；即一个抽象概念；所有 Subject 都绑定 到 SecurityManager，与 Subject 的所有交互都会委托给 SecurityManager；可以把 SecurityManager；可以把 Subject 认 为是一个门面；SecurityManager 才是实际的执行者； SecurityManager：安全管理器；即所有与安全有关的操作都会与 SecurityManager 交互； 且它管理着所有 Subject；可以看出它是 Shiro 的核心，它负责与后边介绍的其他组件进行 交互，如果学习过 SpringMVC，你可以把它看成 DispatcherServlet
