红帽全球峰会3.2. JAAS 核心类
JAAS 核心类可以分成三个类别：常用类、验证类和授权类。下面的列表只列出了常用类和验证类，因为它们是用于实现本章涵盖的JBossSX 功能的专有类。
这些是通用类：
Subject(javax.security.auth.Subject)
这些是验证类：
Configuration(javax.security.auth.login.Configuration)LoginContext(javax.security.auth.login.LoginContext)
这些是相关联的接口：
Principal(java.security.Principal)Callback(javax.security.auth.callback.Callback)CallbackHandler(javax.security.auth.callback.CallbackHandler)LoginModule(javax.security.auth.spi.LoginModule)
