1:环境和版本

java:jdk7

spring:4.1.3

activemq:5.8.0

2:spring与activeMQ的结合配置

</bean>
<!-- ActiveMQ为我们提供了一个PooledConnectionFactory，往里面注入一个ActiveMQConnectionFactory可以用来将Connection,
Session和MessageProducer池化，这样可以大大的减少我们的资源消耗。
问题:使用poolConnectionFactory时候,用JMSTemplate同步循环接收消息,因为JMSTemplate会自动在接收消息后关闭连接,
所以循环到第二次的时候会报错,这个问题待解决
问题:使用poolConnectionFactory时候,用监听来接收消息,会有部分消息残留在队列里面,问题待解决
结论:还是先别用连接池了-->

3:编写send测试类

package com.test.spring;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
/**
* 类描述:sender测试类
*
* @author fengyong
* @version 1.0
* @since 1.0
* Created by fengyong on 16/8/3 下午7:45.
*/
public class ActiveMqSender extends BaseTest {
@Autowired
private JmsTemplate senderJmsTemplate;
@Test
public void activeMq(){
for(int i = 1;i<=10;i++){
senderJmsTemplate.convertAndSend("FirstQueue","我是第"+i+"个");
}
System.out.print("全部执行完毕!!!");
}
}

4:编写receiver测试类

package com.test.spring;
import com.system.freemwork.amq.SimpleJmsTemplate;
import org.apache.activemq.command.ActiveMQQueue;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import javax.jms.JMSException;
import javax.jms.TextMessage;
/**
* 类描述:receiver测试类
*
* @author fengyong
* @version 1.0
* @since 1.0
* Created by fengyong on 16/8/8 下午5:28.
*/
public class ActiveMqReceiver extends BaseTest{
@Autowired
private SimpleJmsTemplate receiverJmsTemplate;
@Autowired
private ActiveMQQueue activeMQQueue;
/**
* 坑爹的方法,如果session事物设置为true,receiver直接将sessioin进行commit,
*
* 如果设置为false,receiver方法会直接判断进行消息确认,无法做到手动的消息确认,所以一旦发生异常,这条消息不会回到消息队列中
*
* session的提交可以认为是消息确认收到
* @throws JMSException
*/
@Test
public void receiver() throws JMSException {
int i=1;
while (true){
i++;
TextMessage message = (TextMessage)receiverJmsTemplate.receive(activeMQQueue);
if (null != message) {
System.out.println("收到消息==================" + message.getText());
} else {
System.out.print("超时10秒");
break;
}
}
}
}

注:如果session事物设置为true,receiver直接将sessioin进行commit.源码如下

if (session.getTransacted()) {
   // Commit necessary - but avoid commit call within a JTA transaction.
   if (isSessionLocallyTransacted(session)) {
      // Transacted session created by this template -> commit.
      JmsUtils.commitIfNecessary(session);
   }
}

如果session事物设置为false,receiver方法会直接判断进行消息确认,无法做到手动的消息确认,所以一旦发生异常,这条消息不会回到消息队列中.源码如下

else if (isClientAcknowledge(session)) {
   // Manually acknowledge message, if any.
   if (message != null) {
      message.acknowledge();
   }
}

所以需要修改源码不让其在receiver的时候自动确认收到消息

5:新建SimpleJmsTemplate继承JmsTemplate

package com.system.freemwork.amq;
import org.springframework.jms.JmsException;
import org.springframework.jms.connection.ConnectionFactoryUtils;
import org.springframework.jms.connection.JmsResourceHolder;

import javax.jms.MessageConsumer;
import javax.jms.Session;

6:第二个receiver测试类

package com.test.spring;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import javax.jms.JMSException;
import javax.jms.TextMessage;
/**
* 类描述:receiver测试类
*
* @author fengyong
* @version 1.0
* @since 1.0
* Created by fengyong on 16/8/8 下午5:28.
*/
public class ActiveMqReceiver extends BaseTest{
@Autowired
private SimpleJmsTemplate receiverJmsTemplate;
@Autowired
private ActiveMQQueue activeMQQueue;
@Test
public void recerver() throws JMSException {
int i=1;
while (true){
i++;
TextMessage message = (TextMessage)receiverJmsTemplate.receive(activeMQQueue);
if (null != message) {
System.out.println("收到消息==================" + message.getText());
if(i==4){
throw new RuntimeException("Exception");
}
receiverJmsTemplate.msgAckAndcloseSession(message);
} else {
System.out.print("超时10秒");
break;
}
}
}
}

7:测试结果

注:接收第三个时失败,虽然这里打印出来了,但是第三个消息并没有被确认接收,同步自定义接收消息修改成功

spring activeMQ使用连接池工厂报错
