Activemq 消息发送、接收java代码实现队列模式

 * 生产类

 */

//队列模式
public static final String queueName = "queue-test";

//5. 创建一个目标
Destination destination = MqSession.session().createQueue(queueName);
//6. 创建一个生产者
MessageProducer producer = MqSession.session().createProducer(destination);


for (int i = 0; i < 100; i++) {
//7. 创建消息
TextMessage textMessage = MqSession.session().createTextMessage("test" + i);
//8. 发布消息
producer.send(textMessage);
System.out.println("发送消息" + textMessage.getText());
}
//9. 关闭链接        
MqSession.session().close();
}
