Spring集成ActiveMQ配置

Spring JMS異步發收消息 ActiveMQ

2.環境

在前面的一篇 ActiveMQ入門實例中我們實現了消息的異步傳送，這篇博文將如何在spring環境下集成ActiveMQ。如果要在spring下集成ActiveMQ，那么就需要將如下jar包導入項目：

本文有兩篇參考文獻，因此有兩個實例，項目結構如下圖所示：

3.實例1

信息發送者：HelloSender.java

package edu.sjtu.erplab.springactivemq;

import javax.jms.JMSException;
import javax.jms.Session;

import javax.jms.Destination;
import javax.jms.Message;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class HelloSender {

/**
* @param args
* jmsTemplate和destination都是在spring配置文件中進行配制的
* Sender只使用了配置文件中的jmsFactory，jmsTemplate，還有destination這三個屬性
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate");
Destination destination = (Destination) applicationContext.getBean("destination");
template.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("發送消息：Hello ActiveMQ Text Message2！");
}
});
System.out.println("成功發送了一條JMS消息");
}
}

信息接受者：ProxyJMSConsumer.java

package edu.sjtu.erplab.springactivemq;

import javax.jms.Destination;
import javax.jms.TextMessage;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;

/**
* JMS消費者
* 消息題的內容定義
* 消息對象 接收消息對象后： 接收到的消息體* <p>
*/
public class ProxyJMSConsumer {

public ProxyJMSConsumer() {

}
private JmsTemplate jmsTemplate;

public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}

/**
* 監聽到消息目的有消息后自動調用onMessage(Message message)方法
*/
public void recive() {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
Destination destination = (Destination) applicationContext.getBean("destination");
while (true) {
try {
TextMessage txtmsg = (TextMessage) jmsTemplate
.receive(destination);
if (null != txtmsg) {
System.out.println("[DB Proxy] " + txtmsg);
System.out.println("[DB Proxy] 收到消息內容為: "
+ txtmsg.getText());
} else
break;
} catch (Exception e) {
e.printStackTrace();
}

}
}

}

客戶端：JMSTest.java

package edu.sjtu.erplab.springactivemq;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class JMSTest {

/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext.getBean("messageReceiver");
proxyJMSConsumer.recive();

System.out.println("初始化消息消費者");
}

}

Spring配置文件：applicationContext-jms.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

</bean>
</property>
<property name="maxConnections" value="100"></property>
</bean>

<!-- Spring JMS Template -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory">
<ref local="jmsFactory" />
</property>
<property name="defaultDestinationName" value="subject" />
<!-- 區別它采用的模式為false是p2p為true是訂閱 -->
<property name="pubSubDomain" value="true" />
</bean>

<!-- 發送消息的目的地（一個隊列） -->
<bean id="destination" class="org.apache.activemq.command.ActiveMQTopic">
<!-- 設置消息隊列的名字 -->
<constructor-arg index="0" value="subject" />
</bean>




<bean id="messageReceiver" class="edu.sjtu.erplab.springactivemq.ProxyJMSConsumer">
<!--class="edu.sjtu.erplab.springactivemq.ProxyJMSConsumer">-->
<property name="jmsTemplate" ref="jmsTemplate"></property>
</bean>



</beans>

測試方法：首先運行JMSTest，然后運行HelloSender。

4.實例2

消息發送者：?Sender

package edu.sjtu.erplab.springactivemq2;

import javax.jms.JMSException;
import javax.jms.MapMessage;
import javax.jms.Message;
import javax.jms.Session;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class Sender {
private JmsTemplate jmsTemplate;
//getter and setter
public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}

public void sendInfo() {
jmsTemplate.send(new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
MapMessage message = session.createMapMessage();
message.setString("lastName", "ppp");
return message;
}

});
}
}

消息發送客戶端：SenderTest

package edu.sjtu.erplab.springactivemq2;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SenderTest {
public static void main(String[] args) {
// TODO 自動生成方法存根
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Sender sender = (Sender) context.getBean("sender");
sender.sendInfo();
}
}

消息接收者：Receiver

package edu.sjtu.erplab.springactivemq2;

import javax.jms.JMSException;
import javax.jms.MapMessage;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.support.JmsUtils;

public class Receiver {
private JmsTemplate jmsTemplate;
//getter and setter
public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}

/**
* 構造函數
*/
public Receiver() {
}

public String receiveMessage() {
String my = "";
MapMessage message = (MapMessage) jmsTemplate.receive();
try {
my = message.getString("lastName");
} catch (JMSException e) {
throw JmsUtils.convertJmsAccessException(e);
}
return my;
}


}

消息接收客戶端：ReceiverTest

package edu.sjtu.erplab.springactivemq2;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ReceiverTest {
public static void main(String[] args) {
// TODO 自動生成方法存根
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Receiver receiver = (Receiver) context.getBean("receiver");
System.out.print(receiver.receiveMessage());
}
}

Spring配置文件：applicationContext.xml
