ActiveMQ 是Apache出品,最流行的,能力强劲的开源消息总线。ActiveMQ 是一个完全支持JMS1.1和J2EE 1.4规范的 JMS Provider实现,尽管JMS规范出台已经是很久的事情了,但是JMS在当今的J2EE应用中间仍然扮演着特殊的地位。
ActiveMQ特性列表
1. 多种语言和协议编写客户端。语言: Java, C, C++, C#, Ruby, Perl, Python, PHP。应用协议: OpenWire,Stomp REST,WS Notification,XMPP,AMQP
2. 完全支持JMS1.1和J2EE 1.4规范 (持久化,XA消息,事务)
3. 对Spring的支持,ActiveMQ可以很容易内嵌到使用Spring的系统里面去,而且也支持Spring2.0的特性
4. 通过了常见J2EE服务器(如 Geronimo,JBoss 4, GlassFish,WebLogic)的测试,其中通过JCA 1.5 resource adaptors的配置,可以让ActiveMQ可以自动的部署到任何兼容J2EE 1.4 商业服务器上
5. 支持多种传送协议:in-VM,TCP,SSL,NIO,UDP,JGroups,JXTA
6. 支持通过JDBC和journal提供高速的消息持久化
7. 从设计上保证了高性能的集群,客户端-服务器,点对点
8. 支持Ajax
9. 支持与Axis的整合
10. 可以很容易得调用内嵌JMS provider,进行测试
1:下载 ActiveMQ 5.6.0 Release
http://activemq.apache.org/download.html
放到d盘
2:运行apache-activemq服务:双击 activemq.bat
3:效果
4:所需jar包
5:spring配置文件applicationContext.xml

<? xml version = "1.0" encoding = "UTF-8" ?>
< beans > < bean id = "connectionFactory" class = "org.apache.activemq.ActiveMQConnectionFactory" > < property name = "brokerURL" > < value >tcp://localhost:61616?wireFormat.maxInactivityDuration=0</ value > </ property > </ bean > < bean id = "jmsTemplate" class = "org.springframework.jms.core.JmsTemplate" > < property name = "connectionFactory" > < ref bean = "connectionFactory" /> </ property > </ bean > < bean id = "destination" class = "org.apache.activemq.command.ActiveMQQueue" > < constructor-arg index = "0" > < value >MessageQueue</ value > </ constructor-arg > </ bean > </ beans > |
这时主要是配置activemq服务信息与实现springjms的对应接口

9:测试
运行 发送方和接收方 (顺序随便) main文件,效果如下:
注:即使 接收方启动晚,或者 发送方关闭了, 接收方都会正常接收完所有数据
