root用户

test用户

SecurityUtils. getSubject()，可以获得当前正在执行的Subject. 一个Subject就是一个应用程序的用户的安全。实际上称它为“User”，但太多的应用程序拥有已经拥有自己的 User 类/框架的现有 API，我们不想与它们发生冲突。此外，在安全领域，该术语Subject实际上是公认的术语。

getSubject()独立应用程序中的调用可能会Subject在特定于应用程序的位置返回基于用户数据的 ，并且在服务器环境（例如 Web 应用程序）中，它Subject根据与当前线程或传入请求关联的用户数据获取。

Session session = currentUser.getSession();
session.setAttribute( "someKey", "aValue" );

这Session是一个特定于 Shiro 的实例，它提供了您习惯于使用常规 HttpSessions 的大部分内容，但还有一些额外的好处和一个很大的区别：它不需要 HTTP 环境！
