SPRING JMS 整合ACTIVEMQ

  近日用spring3.2 jms 与activemq5.8 整合一下，实现了异步发送，异步接收功能，并附上了测试代码

1 ）UML 如下
   [img]
  

    消息的接受完全是托管到org.springframework.jms.listener.DefaultMessageListenerContainer 中来处理   ,发送client 无需关心消息的接受
   [/img]
2 )applicationContext.xml 片段

 <bean id="taskExecutor"
		class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
		<!-- 核心线程数，默认为1 -->
		<property name="corePoolSize" value="5" />
		<!-- 最大线程数，默认为Integer.MAX_VALUE -->
		<property name="maxPoolSize" value="5" />
		<!-- 队列最大长度，一般需要设置值>=notifyScheduledMainExecutor.maxNum；默认为Integer.MAX_VALUE -->
		<property name="queueCapacity" value="1000" />
		<!-- 线程池维护线程所允许的空闲时间，默认为60s -->
		<property name="keepAliveSeconds" value="300" />
		<!-- 线程池对拒绝任务（无线程可用）的处理策略，目前只支持AbortPolicy、CallerRunsPolicy；默认为后者 -->
		<property name="rejectedExecutionHandler">
			<!-- AbortPolicy:直接抛出java.util.concurrent.RejectedExecutionException异常 -->
			<!-- CallerRunsPolicy:主线程直接执行该任务，执行完之后尝试添加下一个任务到线程池中，可以有效降低向线程池内添加任务的速度 -->
			<!-- DiscardOldestPolicy:抛弃旧的任务、暂不支持；会导致被丢弃的任务无法再次被执行 -->
			<!-- DiscardPolicy:抛弃当前任务、暂不支持；会导致被丢弃的任务无法再次被执行 -->
			<bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy" />
		</property>
	</bean>
          <!--jms 连接池--
            optimizedAckScheduledAckInterval:消息确认周期

           -->
          
	<bean id="jmsConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
		<property name="connectionFactory">
			<bean class="org.apache.activemq.ActiveMQConnectionFactory">
				<property name="brokerURL" value="tcp://localhost:61616" />
				<property name="closeTimeout" value="60000" />
				<property name="userName" value="admin" />
				<property name="password" value="admin" />
				<!--<property name="optimizeAcknowledge" value="true" />-->
				<property name="optimizedAckScheduledAckInterval" value="10000" />
			</bean>
		</property>
	</bean>

	<!-- Spring JMS Template -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
		<property name="connectionFactory">
			<ref local="jmsConnectionFactory" />
		</property>
	</bean>
         
	         <!--queue通道-->
	<bean id="asyncQueue" class="org.apache.activemq.command.ActiveMQQueue">
		<constructor-arg index="0">
			<value>asyncQueue</value>
		</constructor-arg>
	</bean>
         <!--topic通道-->
	<bean id="asyncTopic" name="asyncTopic"
		class="org.apache.activemq.command.ActiveMQTopic">
		<constructor-arg index="0">
			<value>asyncTopic</value>
		</constructor-arg>
	</bean>
         <!--消息接受容器，多线程异步接受消息-->
	<bean id="jmsContainer"
		class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="jmsConnectionFactory" />
		<property name="destination" ref="asyncTopic" />
		<property name="messageListener" ref="messageListener" />
		<property name="sessionTransacted" value="false" />
	</bean>
         <!--消息接受pojo-->
	<bean id="messageReceiver" class="com.cn.ld.modules.jms.worker.JmsReceiver" />
         <!--消息发送pojo-->
	<bean id="messageSender" class="com.cn.ld.modules.jms.worker.JmsSender" />
          <!--异步接收的消息监听器-->
	<bean id="messageListener"
		class="org.springframework.jms.listener.adapter.MessageListenerAdapter">
		<constructor-arg>
			<ref bean="messageReceiver" />
		</constructor-arg>
	</bean>

3)java 相关class 代码
    MessageHandler 消息接受的接口
 

package com.cn.ld.modules.jms.handler;

import java.io.Serializable;

public interface MessageHandler {
	void receive(TextMessage message);
	
	
	void handleMessage(String message);

	void handleMessage(Map<String, Object> message);

	void handleMessage(byte[] message);

	void handleMessage(Serializable message);
}

  

  JmsReceiver  消息接受实现类
 

   package com.cn.ld.modules.jms.worker;

import java.io.Serializable;

public class JmsReceiver implements MessageHandler {
	private Collection<String> collection;

	@Override
	public void receive(TextMessage message) {
		try {
			if (collection == null) {
				this.collection = new ArrayList<String>();
			}
			collection.add(message.getText());
		} catch (JMSException e) {
			e.printStackTrace();
		}
	}
	
	
	@Override
	public void handleMessage(String message) {
		/*
		 * if(collection == null){ this.collection = new ArrayList<String>(); }
		 * collection.add(message);
		 */
	}

	@Override
	public void handleMessage(Map<String, Object> message) {
		Set<String> keySet = message.keySet();
		Iterator<String> keys = keySet.iterator();
		while (keys.hasNext()) {
			String key = keys.next();
			System.out.println(message.get(key));
		}

	}

	@Override
	public void handleMessage(byte[] message) {

	}

	@Override
	public void handleMessage(Serializable message) {
	}

	public Collection<String> getCollection() {
		return collection;
	}

	public void setCollection(Collection<String> collection) {
		this.collection = collection;
	}

}

  

  
  JmsSender 消息发送 支持异步发送
 

package com.cn.ld.modules.jms.worker;

import java.util.Collection;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.task.TaskExecutor;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.util.Assert;

import com.cn.ld.modules.annotation.MethodMonitorCount;

public class JmsSender {

	@Autowired
	private JmsTemplate jmsTemplate;
        
	@Autowired
	private TaskExecutor taskExecutor;

	private Destination destination;

	private boolean isSendAsync = false;

	public JmsSender(){}
	public JmsSender(Destination destination) {
		if (null == destination)
			this.destination = new ActiveMQTopic("topic");
		else
			this.destination = destination;
	}

	
	public void sendSingle(String message,Destination destination) {
		sendMessage(message,destination);
	}

	public void sendBatch(Collection<?> messages,Destination destination) {
		Assert.notNull(messages, "param 'messages' can't be null !");
		Assert.notEmpty(messages, "param 'message' can't be empty !");
		for (Object message : messages) {
			if (null != message && message instanceof String) {
				sendSingle(String.valueOf(message),destination);
			}
		}
	}

	private void sendMessage(final String message,Destination destination) {
		final Destination sendDest = destination ;
		if (isSendAsync) {
			taskExecutor.execute(new Runnable() {
				@Override
				public void run() {
					send(message,sendDest);
				}
			});
		} else {
			send(message,destination);
		}
	}

	private void send(final String message,Destination destination) {
		this.jmsTemplate.send(destination, new MessageCreator() {
			@Override
			public Message createMessage(Session session) throws JMSException {
				return session.createTextMessage(message);
			}

		});
	}

	public boolean isSendAsync() {
		return isSendAsync;
	}
	
	public void setSendAsync(boolean isSendAsync) {
		this.isSendAsync = isSendAsync;
	}

	public Destination getDestination() {
		return destination;
	}

}

  

  

4) test case

package com.cn.ld.modules.jms;

import java.io.File;
import java.io.IOException;

import org.apache.activemq.command.ActiveMQTopic;
import org.apache.log4j.Logger;
import org.aspectj.util.FileUtil;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.cn.ld.modules.jms.worker.JmsSender;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class JmsTest {
	protected final Logger logger = Logger.getLogger(this.getClass());

	@Autowired
	private JmsSender jmsSender;

	private String destination;
	private int no = 10* 10000;
	private String message;

	@Before
	public void init() throws IOException {
		String filePath = Thread.currentThread().getContextClassLoader()
				.getResource("").getPath()
				+ "message.txt";
		message = FileUtil.readAsString(new File(filePath));
		this.destination = "asyncTopic";
                  //开启异步发送
		this.jmsSender.setSendAsync(true);
	}

	@Test
	public void send() throws InterruptedException {
		ActiveMQTopic dest = new ActiveMQTopic(this.destination);
		for (int i = 0; i < no; i++) {
			jmsSender.sendSingle(message, dest);
		}
		Thread.sleep(1000000000);
	}

}

请问这是订阅模式的配置吗？

怎么接收？
