配置消息目标地址

接受消息

package com.java;import javax.ejb.ActivationConfigProperty;import javax.ejb.MessageDriven;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;@MessageDriven(activationConfig = {@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),@ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/mytopic") })public class MyMDBBean implements MessageListener {public void onMessage(Message msg) {try {TextMessage textMessage = (TextMessage) msg;System.out.println("MyTopicMDBBean被调用了【" + textMessage.getText()+ "】");} catch (JMSException e) {e.printStackTrace();}}}

创建消息生产者
