Sprng-jms消息服务小项目
所需的包:
spring的基础包
spring-jms-xx包
spring-message–xx包
commons-collection-xx包
commons-pool2-xx包
aop切面的包: spring-aop,spring-aspect,aopalliance,aspectjrt.jar,aspectjweaver.jar
配置:
1.配置ConnectionFactory
2.配置jmsTemplate;
3.配置Destination
4.配置listener
5.配置container
话不多说,直接上代码
前提是你已经开启了activemq服务
看一下项目架构
临听器有两种实现方案: 一种是采用原生的jms的MessageListener
另一种是采用spring的方案:SessionAwareMessageListener
前一种只能消费消息,不能发送回送消息
后一种可以再接到消息后,给生产者回送消息,它自己即是生产者也是消费者
所有所需的连接工、目的地等都是通过Spring注入的,具体看后面的配置文件
发送消息的接口:
package com.tg.service;
public interface PersonService {
public void sendMessage(String message);
}
生产者一:
package com.tg.service; import javax.annotation.Resource; import javax.jms.DeliveryMode; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Session; import org.springframework.context.annotation.Scope; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.stereotype.Service; @Service("personServiceImpl") @Scope("prototype") public class PersonServiceImpl implements PersonService { private Destination destination; private JmsTemplate jsmTemplate; private Destination replyQueueDestination; @Override public void sendMessage(final String message) { System.out.println("生产者发送消息"+ message); //回调 jsmTemplate.send(destination, new MessageCreator(){ @Override public Message createMessage(Session session) throws JMSException { //创建一个文本消息 Message msg = session.createTextMessage(message); //指定为非持久化方式 msg.setJMSDeliveryMode( DeliveryMode.NON_PERSISTENT ); return msg; } }); } @Resource(name="queueDestination") public void setDestination(Destination destination) { this.destination = destination; } @Resource(name="jmsTemplate") public void setJsmTemplate(JmsTemplate jsmTemplate) { this.jsmTemplate = jsmTemplate; } @Resource(name = "replyQueueDestination") public void setReplyDestination(Destination replyDestination) { this.replyQueueDestination = replyDestination; } }
消费者一:
package com.tg.service; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; //临听器有两种实现方案: 一种是采用原生的jms的MessageListener // 另一种是采用spring的方案:SessionAwareMessageListener //注意: 这里的MessageListener接口是 jms的接口 public class ConsumerMessageListener1 implements MessageListener { @Override public void onMessage(Message message) { if( message instanceof TextMessage){ TextMessage text=(TextMessage) message; System.out.println("接收到的消息是一个文本消息:"+ text); //这种方式无法回复 所以采用第二种 } } }
生产者二:
package com.tg.service; import javax.annotation.Resource; import javax.jms.DeliveryMode; 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 org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.stereotype.Service; @Service("personServiceImpl2") public class PersonServiceImpl2 implements PersonService { private Destination destination; //用于存发送信息的队列 private JmsTemplate jsmTemplate; //jms操作模板 private Destination replyQueueDestination; //用于存回复信息的队列, @Override public void sendMessage(final String message) { System.out.println("生产者2->发送消息" + message); // 回调 jsmTemplate.send(destination, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { Message msg = session.createTextMessage(message); // 设置回复的信息的目的地. msg.setJMSReplyTo(replyQueueDestination); // 设置发送的信息类型 为非持久化信息 msg.setJMSDeliveryMode(DeliveryMode.NON_PERSISTENT); //创建一个消费者,用于接收对方回复的信息 注意,这个消费者临听 replyDestination MessageConsumer comsumer2 = session.createConsumer(replyQueueDestination); comsumer2.setMessageListener(new MessageListener() { public void onMessage(Message m) { try { System.out.println("接收到的回复信息:" + ((TextMessage) m).getText()); } catch (JMSException e) { e.printStackTrace(); } } }); return msg; } }); } @Resource(name = "replyQueueDestination") public void setReplyDestination(Destination replyDestination) { this.replyQueueDestination = replyDestination; } @Resource(name = "sendQueueDestination") public void setDestination(Destination destination) { this.destination = destination; } @Resource(name = "jmsTemplate") public void setJsmTemplate(JmsTemplate jsmTemplate) { this.jsmTemplate = jsmTemplate; } }
消费者二:
package com.tg.service; import javax.annotation.Resource; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageProducer; import javax.jms.Session; import javax.jms.TextMessage; import org.springframework.jms.listener.SessionAwareMessageListener; import org.springframework.stereotype.Component; /** * SessionAwareMessageListener:是由spring提供,它可以在回调方法中传入session,以此回送信息到生产者 * @author Administrator * */ @Component("consumerMessageListener2") public class ConsumerMessageListener2 implements SessionAwareMessageListener<TextMessage> { private Destination destination; @Override public void onMessage(TextMessage message, Session session) throws JMSException { System.out.println("接收到的消息是一个文本消息:"+ message.getText()); //通过session 创建 producer对象,再回送信息 //从message中取出信息回送的目的地,以便创建生产者. MessageProducer producer=session.createProducer( message.getJMSReplyTo() ); //创建一条消息 Message textMessage=session.createTextMessage( "生产者发过来的信息已经处理完毕,game over..." ); //调用发送 producer.send(textMessage); } @Resource(name="sendQueueDestination") public void setDestination(Destination destination) { this.destination = destination; } }
Spring的配置文件:

第一种的测试类:
package com.tg.test; import org.apache.xbean.spring.context.ClassPathXmlApplicationContext; import org.springframework.context.ApplicationContext; import com.tg.service.PersonService; //测试生产者发送了一个消息,消费者接收 //整合spring http://haohaoxuexi.iteye.com/blog/1893038 public class Test1 { public static void main(String[] args) { ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml"); PersonService ps=(PersonService) ac.getBean("personServiceImpl"); for( int i=0;i<10;i++){ Thread t=new Thread(new User(ps,"汤"+i)); t.start(); } } } class User implements Runnable{ private PersonService ps; private String name; public User(PersonService ps, String name) { super(); this.ps = ps; this.name = name; } @Override public void run() { for( int i=0;i<10;i++){ ps.sendMessage(name+"向你问好"); } } }
运行结果 :
第二种方案测试类:
package com.tg.test; import org.apache.xbean.spring.context.ClassPathXmlApplicationContext; import org.springframework.context.ApplicationContext; import com.tg.service.PersonService; //测试生产者发送了一个消息,消费者接收后,再回复一个信息到生产者,生产者接收到后,显示这个回复的信息 public class Test2 { public static void main(String[] args) { ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml"); PersonService ps=(PersonService) ac.getBean("personServiceImpl2"); for( int i=0;i<10;i++){ Thread t=new Thread(new User(ps,": 汤1"+i)); t.start(); } } }
运行结果 :
