课程名称：Java EJB 精通：逐步掌握 EJB 应用程序 课程概述： EJB（企业 Java Bean）用于开发可扩展、稳健且安全的企业应用程序。与 EJB 2 相比，EJB 3 的开发速度更快，原因在于其简单性以及多个注解的使用，如 @EJB、@Stateless、@Stateful、@TransactionManagement、@Resources 和 @SessionContext 等。本课程将深入探讨 EJB 规范的各个主题，包括 EJB 的定义及其优点，会议 Bean 的概念及其类型，如无状态会议 Bean、状态会议 Bean，以及它们的生命周期和示例。此外，课程将涵盖 JMS（Java 消息服务），教授如何为分布式应用程序创建强健的异步消息，包括消息域的概念、JMS 队列和主题的使用方法，以及消息驱动 Bean（MDB）的功能。最后，课程将提到在 EJB 3.2 中，实体 Bean 的弃用及其被 JPA 取代的背景。 通过本课程，学员将全面提高在 Java EJB 开发中的技术能力，为构建企业级应用打下坚实的基础。
