资料简介:
《Java消息服务》第二版,是对标准API的一个彻底详尽的介绍——它支持消息传递,即网络计算机间的关键数据从软件到软件的交换。你将学习到JMS如何帮助你解决许多架构难题,如整合不同的系统和应用程序,增加可扩展性,消除系统瓶颈,支持并行处理,提升灵活性和敏捷性。由于更新了JMS 1.1,第二版还说明了厂商无关的规范将有助于你写基于messaging的应用程序,无论是使用IBM的MQ、Progress软件的SonicMQ、ActiveMQ的,还是其他专有的消息服务。
有了《Java消息服务》,你将可以: 使用点对点和出版与订阅消息传递模型建立应用程序 使用如事务和持久订阅功能,以使应用程序可靠 使用消息驱动的beans在Enterprise JavaBeans(EJB)中实现消息传递 使用JMS时结合RESTful应用程序和Spring应用程序框架 消息传递是一个强大的范例,可以更容易地使企业应用程序的不同部分分离。《Java消息服务》第二版将迅速教会你如何运用其背后的关键技术。
