ActiveMQ应用笔记二：Producer与Consumer模板代码
接上一篇文章。
ActiveMQ成功部署运行后，就可以开发producer和consumer了。
在eclipse中新建Java项目，将ActiveMQ安装目录下lib中的jar包都引入项目，然后就可以编写producer和consumer。
注意：如果是测试代码，为了真实性，最好把producer和consumer分开写，而不是写在一个类中。
1.Producer:
package com.liyang.activemq;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnectionFactor y;
public class Sender_lion {
public static void main(String[] args) {
ConnectionFactory connectionFactory;
Connection connection = null;
Session session;
Destination destination;
MessageProducer producer;
//参数为用户名，密码，MQ的url
connectionFactory = new ActiveMQConnectionFactory(
"smechina",
"fulong",
"tcp://localhost:61616");
try {
connection = connectionFactory.createConnection();
connection.start();
session = connection.createSession(Boolean.TRUE,
Session.AUTO_ACKNOWLEDGE);
//*******注意：此处需修改为topic才能支持1对多发信息
//destination = session.createQueue("FirstQueue");
destination = session.createTopic("FirstTopic");
// 得到消息生成者【发送者】
producer = session.createProducer(destination);
// ********设置是否持久化
//producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
//uandp是需要发送的消息
String uandp = "liyang:fulong";
sendMessage(session, producer,uandp);
session.commit();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != connection)
connection.close();
} catch (Throwable ignore) {
}
}
}
public static void sendMessage(Session session, MessageProducer producer,String passport)
throws Exception {
// 发送10条消息
for (int i = 0; i < 9; i++) {
TextMessage message = session.createTextMessage("账号"+i+":" + passport);
//System.out.println("账号是:" + passport);
//可设置属性过滤
//message.setStringProperty("receiver", "A");
producer.send(message);
}
}
}
1.Consumer:
package com.liyang.activemq;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.jms.Topic;
import org.apache.activemq.ActiveMQConnectionFactor y;
public class Receiver_lion{
public static void main(String[] args) {
ConnectionFactory connectionFactory;
Connection connection = null;
Session session;
Destination destination;
MessageConsumer consumer;
//参数为用户名，密码，MQ的url
connectionFactory = new ActiveMQConnectionFactory(
"smeguangdong",
"fulong",
"tcp://localhost:61616");
try {
connection = connectionFactory.createConnection();
//---持久化订阅才使用下语句！！！！参数是clientid，设置该参数后MQ会记住该ID---
connection.setClientID("guangdong");
connection.start();
session = connection.createSession(Boolean.FALSE,
Session.AUTO_ACKNOWLEDGE);
//*******注意：此处需修改为topic才能支持1对多发信息
//destination = session.createQueue("FirstQueue");
destination = session.createTopic("FirstTopic");
//创建普通消费者【接收者】，使用属性过滤
//consumer = session.createConsumer(destination,"receiver = 'A'");
//--------持久化订阅！！！！------第二个参数是client名
consumer = session.createDurableSubscriber((Topic)destination,"guangdong");
MessageListener ml = new MessageListener(){
@Override
//设置监听器
public void onMessage(Message m) {
TextMessage textMsg = (TextMessage) m;
try{
System.out.println("收到消息:" + textMsg.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
};
consumer.setMessageListener(ml);
while (true) {
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != connection)
connection.close();
} catch (Throwable ignore) {
}
}
}
}
