ActiveMQ实战(五)--Spring整合ActiveMQ实现点对点与主题发布订阅通信

四、一些类

两个Controller类,一个用来测试点对点通信,另一个是用来测试点对点与主题发布订阅通信:

点对点通信控制类:

package com.fendo.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.fendo.service.ConsumerService;
import com.fendo.service.ProducerService;

import javax.annotation.Resource;
import javax.jms.Destination;
import javax.jms.TextMessage;

/**
*
* @author fendo
*
*/
@Controller
public class MessageController {

private Logger logger = LoggerFactory.getLogger(MessageController.class);

@Resource(name = "demoQueueDestination")
private Destination destination;

//队列消息生产者
@Resource(name = "producerService")
private ProducerService producer;

//队列消息消费者
@Resource(name = "consumerService")
private ConsumerService consumer;

@RequestMapping(value = "/SendMessage", method = RequestMethod.POST)
@ResponseBody
public void send(String msg) {
logger.info(Thread.currentThread().getName()+"------------send to jms Start");
producer.sendMessage(msg);
logger.info(Thread.currentThread().getName()+"------------send to jms End");
}

@RequestMapping(value= "/ReceiveMessage",method = RequestMethod.GET)
@ResponseBody
public Object receive(){
logger.info(Thread.currentThread().getName()+"------------receive from jms Start");
TextMessage tm = consumer.receive(destination);
logger.info(Thread.currentThread().getName()+"------------receive from jms End");
return tm;
}

}

主题发布订阅通信:

package com.fendo.controller;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import com.fendo.producer.queue.QueueSender;
import com.fendo.producer.topic.TopicSender;

/**
*
* @author fendo
* @description controller测试
*/
@Controller
@RequestMapping("/activemq")
public class ActivemqController {

@Autowired
QueueSender queueSender;

@Autowired
TopicSender topicSender;

/**
* 发送消息到队列
* Queue队列：仅有一个订阅者会收到消息，消息一旦被处理就不会存在队列中
* @param message
* @return String
*/
@ResponseBody
@RequestMapping("queueSender")
public String queueSender(@RequestParam("message")String message){
String opt="";
try {
queueSender.send("test.queue", message);
opt = "suc";
} catch (Exception e) {
opt = e.getCause().toString();
}
return opt;
}

/**
* 发送消息到主题
* Topic主题 ：放入一个消息，所有订阅者都会收到
* 这个是主题目的地是一对多的
* @param message
* @return String
*/
@ResponseBody
@RequestMapping("topicSender")
public String topicSender(@RequestParam("message")String message){
String opt = "";
try {
topicSender.send("test.topic", message);
opt = "suc";
} catch (Exception e) {
opt = e.getCause().toString();
}
return opt;
}

}

一个消费者里面包含queue和topic

queue包下有QueueReceiver1和QueueReceiver2

QueueReceiver1

package com.fendo.consumer.queue;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.springframework.stereotype.Component;

/**
*
* @author fendo
* @description  队列消息监听器
*
*/
@Component
public class QueueReceiver1 implements MessageListener {

@Override
public void onMessage(Message message) {
try {
System.out.println("QueueReceiver1接收到消息:"+((TextMessage)message).getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
}

QueueReceiver2

package com.fendo.consumer.queue;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.springframework.stereotype.Component;

/**
*
* @author fendo
* @description  队列消息监听器
*
*/
@Component
public class QueueReceiver2 implements MessageListener {

@Override
public void onMessage(Message message) {
try {
System.out.println("QueueReceiver2接收到消息:"+((TextMessage)message).getText());
} catch (JMSException e) {
e.printStackTrace();
}
}

}

topic包下有TopicReceiver1,TopicReceiver2

TopicReceiver1

package com.fendo.consumer.topic;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.springframework.stereotype.Component;

/**
*
* @author fendo
* @description  Topic消息监听器
*
*/
@Component
public class TopicReceiver1 implements MessageListener{

@Override
public void onMessage(Message message) {
try {
System.out.println("TopicReceiver1接收到消息:"+((TextMessage)message).getText());
} catch (JMSException e) {
e.printStackTrace();
}
}

}

TopicReceiver2

package com.fendo.consumer.topic;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.springframework.stereotype.Component;

/**
*
* @author fendo
* @description  Topic消息监听器
*
*/
@Component
public class TopicReceiver2 implements MessageListener{

@Override
public void onMessage(Message message) {
try {
System.out.println("TopicReceiver2接收到消息:"+((TextMessage)message).getText());
} catch (JMSException e) {
e.printStackTrace();
}
}

}

五、测试

A.点对点通信

1）手动测试点对点通信

首先运行项目,然后访问: http://localhost:8080/Spring_ActiveMQ/sendMessage.jsp


输入要发送的内容,点击发送,控制台打印如下



ActiveMQ控制台会多出一条记录



然后访问地址:http://localhost:8080/Spring_ActiveMQ/ReceiveMessage.jsp 接受消息



点击"接受消息",控制台会打印出生产者发送的消息



2）自动监听点对点通信

在实际项目中，我们很少会自己手动去获取消息，而是使用一个监听器来监听是否有消息到达，这样子可以很快的完成对消息的处理。

在ActiveMQ.xml配置文件中有段代码是用来配置监听器的

<!-- 配置消息队列监听者（Queue） -->
<bean id="queueMessageListener" class="com.fendo.filter.QueueMessageListener" />

<!-- 显示注入消息监听容器（Queue），配置连接工厂，监听的目标是demoQueueDestination，监听器是上面定义的监听器 -->
<bean id="queueListenerContainer"
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="connectionFactory" />
<property name="destination" ref="demoQueueDestination" />
<property name="messageListener" ref="queueMessageListener" />
</bean>

QueueMessageListener类为

package com.fendo.filter;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

/**
*
* @author fendo
*
*/
public class QueueMessageListener implements MessageListener {
public void onMessage(Message message) {
TextMessage tm = (TextMessage) message;
try {
System.out.println("QueueMessageListener监听到了文本消息：\t"
+ tm.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
}

这样的话，我们在发消息的时候，后台就会自动的监听



注意:当开启自动监听以后,手动访问就会失效。

B.主题发布订阅通信

当访问: http://localhost:8080/Spring_ActiveMQ/index.jsp


输入要发送的内容，然后点击发送Queue消息,会发现后台只有一个接受到了信息



然后发送Topic消息,后台两个都收到了信息



从上面可看出队列模型和PUB/SUB模型的区别，Queue只能由一个消费者接收，其他Queue中的成员无法接受到被已消费的信息，而Topic则可以，只要是订阅了Topic的消费者，全部可以获取到生产者发布的信息。
