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;
}
}
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
}
}
}
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;
}
}
最后看一些Spring的配置文件

看一下第一种的测试类

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
