subscribtopic.closeResource();

}//end class
以上是队列和主题的编码，下面是启动ActiveMQ的类
package com.by.ptop;
import org.apache.activemq.broker.BrokerService;
public class CreateServer {
public void startServer()
{
BrokerService broker = new BrokerService();
// 配置jms服务器
try {
broker.addConnector("tcp://localhost:61616");
broker.start();
System.out.println("jms服务器已经启动.");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args)
{
CreateServer cs = new CreateServer();
cs.startServer();
}
}
下面是测试用的：
package com.example;
import javax.jms.JMSException;
import javax.jms.QueueSession;
import javax.jms.TopicSession;
import com.by.ptop.CreateServer;
public class MyTest {
public static void main(String[] args) throws JMSException {
// 启动jms服务器
CreateServer cs = new CreateServer();
cs.startServer();
for(int i = 1;i<=9;i++)
{
// 队列 发送端得编程
// My sendqueue = new My();
// sendqueue.setDurable(false);
// sendqueue.setPersistent(false);
// sendqueue.setTransacted(false);
// sendqueue.setTopic(false);
// sendqueue.setAcknowledgementMode(QueueSession.AUTO_ACKNOWLEDGE);
// sendqueue.setQueueSendName("kkk");
// sendqueue.sendTextMessage("zz"+i);
// sendqueue.closeResource();
// 主题 接收端得编程
My publishtopic = new My();
publishtopic.setDurable(true);
publishtopic.setClientId("opop");
publishtopic.setDurableName("ww");
publishtopic.setPersistent(false);
publishtopic.setTransacted(false);
publishtopic.setTopic(true);
publishtopic.setAcknowledgementMode(TopicSession.AUTO_ACKNOWLEDGE);
publishtopic.setTopicPublishName("eee");
publishtopic.publishTextMessage("zz"+i);
publishtopic.closeResource();
}
}
}
以上是本人初学jms时写的，如有不足之处或者您有更好的代码，还望各位不吝赐教。小弟在这里先谢谢大家了。
