}測試：

SecurityUtils. getSubject()，可以獲得當前正在執行的Subject. 一個Subject就是一個應用程序的用戶的安全。實際上稱它為“User”，但太多的應用程序擁有已經擁有自己的 User 類/框架的現有 API，我們不想與它們發生沖突。此外，在安全領域，該術語Subject實際上是公認的術語。
getSubject()獨立應用程序中的調用可能會Subject在特定于應用程序的位置返回基于用戶數據的 ，并且在服務器環境（例如 Web 應用程序）中，它Subject根據與當前線程或傳入請求關聯的用戶數據獲取。
Session session = currentUser.getSession(); session.setAttribute( "someKey", "aValue" );
這Session是一個特定于 Shiro 的實例，它提供了您習慣于使用常規 HttpSessions 的大部分內容，但還有一些額外的好處和一個很大的區別：它不需要 HTTP 環境！
