本文介绍了一个使用JBoss应用服务器实现消息队列的例子，包括如何通过客户端发送消息到队列，以及如何在服务器端配置并接收这些消息。同时解决了在启动过程中遇到的队列未找到的问题。

Service：

package com.test.ejb;

import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
import javax.ejb.ActivationConfigProperty;
@MessageDriven(
activationConfig ={
@ActivationConfigProperty(propertyName="destinationType",propertyValue="javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination",propertyValue="queue/myqueue")
}
)

public class MyQueueMDBBean implements MessageListener {

public void onMessage(Message msg) {
  TextMessage textMessage =(TextMessage)msg;

  try {
   System.out.println("MyQueueMDBBean被调用了【"+textMessage.getText()+"】");

  } catch (JMSException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }


}

}

Client:

package com.test.ejb;

import javax.jms.JMSException;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.TextMessage;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class MyQueueMDBBeanClient {

/**
* @param args
*/
public static void main(String[] args) {

  try {
   //获取QueueConnectionFactory对象
   InitialContext context =new InitialContext();
   QueueConnectionFactory factory =(QueueConnectionFactory)context.lookup("ConnectionFactory");

   //创建QueueConnection
   QueueConnection connnection =factory.createQueueConnection();

   //创建QueueSession
   QueueSession session =connnection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);

   //获取Destination对象
   Queue queue =(Queue)context.lookup("queue/myqueue");

   //获取文本信息
   TextMessage msg =session.createTextMessage("世界你好啊！");

   //创建发送者
   QueueSender sender =session.createSender(queue);

　//关闭会话
session.close();
connnection.close();

   //发送消息
   sender.send(msg);

   System.out.println("消息已发送");
  } catch (NamingException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (JMSException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

}

发布启动Jboss时出现异常：

解决办法：

我发现在JBoss根目录\server\default\deploy 下的mail-service.xml文件中加入如下：

<mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.org.destination:server=Queue,name=myqueue" >
　　<attribute name="JNDIName" >queue/myqueue</attribute>
　　<depends optional-attribute-name = "DestinationManager" > jboss.mq:service=DestinationManager </depends>
</mbean>

重启JBoss问题即解决。

topic找不到
  <mbean code="org.jboss.mq.server.jmx.Topic" name="jboss.org.destination:server=Topic,name=mytopic" > 
     
     <attribute name="JNDIName">topic/mytopic</attribute> 
     <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends> 
   </mbean>
