activeMQ 特点、实战

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。

主要特点：

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

task_dest为发送端的消息队列，接收端监听执行后将执行结果反回给defaultResponseQueue，发送端接收后根据参数保存数据库。两个项目的交互

一端只需配置一个发送目的地标签，回复是接收别的项目的回复信息

ResponseListener

import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;import org.springframework.beans.factory.annotation.Autowired;import com.eciyuanjie.task.service.TaskLogService;public class ResponseListener implements MessageListener {@Autowiredprivate TaskLogService taskLogService;@Overridepublic void onMessage(Message message) {if(message instanceof TextMessage){TextMessage msg = (TextMessage)message;try {System.out.println("返回内容：-----------"+msg.getText());String []args = msg.getText().split("_");taskLogService.update(Integer.parseInt(args[2]));} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}

发送代码

((JmsService) ApplicationContextHolder.getBean("jmsServiceImpl")).sendTextMessage(MessageType.task_info, ""+className+"_"+methodName+"_"+taskId);

MessageType是自己定义的枚举

public enum MessageType {
task_info
}
