Spring JBOSS MQ JMS的开发应用

如果用过JMS的话，会发现它类似写JDBC或JCA代码。它有创建或检索JMS资源的样板代码，每当你需要编写一个新类来发送或接受消息时，都得重复编写那个样本代码。下面列出了传统JMS实现涉及的步骤：

1、创建JNDI初始上下文context；
2、从JNDI上下文获得队列连接工厂；
3、从队列连接工厂取得队列Queue；
4、创建一个Session对象；
5、创建一个发送或接受对象；
6、利用第5部创建的发送或接受对象发送或接受消息；
7、处理完消息后，关闭所有JMS资源。

在JBOSS中配置：

 

<?xml version="1.0" encoding="UTF-8"?>
<!-- $Id: mail-service.xml 62350 2007-04-15 16:50:12Z [e-mail] $ -->
<server>

  <!-- ==================================================================== -->
  <!-- Mail Connection Factory                                              -->
  <!-- ==================================================================== -->

  <mbean code="org.jboss.mq.server.jmx.Queue"
         name="jboss.mq.destination:service=Queue,name=longgangbai">
    <attribute name="JNDIName">queue/longgangbai</attribute>
    <depends optional-attribute-name="DestinationManager" >jboss.mq:service=DestinationManager</depends>
  </mbean>

</server>

 

Spring中JMS的配置如下：

 

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

 <!-- 设置消息服务的初始化参数信息 -->
 <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate">
      <property name="environment">
           <props>
               <prop key="java.naming.factory.initial">
                   org.jnp.interfaces.NamingContextFactory
               </prop>
               <prop key="java.naming.provider.url">

               </prop>
           </props>
      </property>
  
 </bean>
<!--

                 JMS1.02 TopicConnectionFactory 和QueueConnectionFactory

 -->
<bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
   <property name="jndiName">
       <value>ConnectionFactory</value>
   </property>
   <property name="jndiTemplate">
        <ref local="jndiTemplate"/>
   </property>
</bean>
<!-- 创建JMS的目的地信息 -->
<bean  id="destination" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName">
        <value>queue/longgangbai</value>
     </property>
     <property name="jndiTemplate">
         <ref  local="jndiTemplate"/>
     </property>
</bean>

<!-- 创建JMS发送信息的模板的对象 -->
<bean  id="jmsTemplate"  class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory">
       <ref  local="connectionFactory"/>
     </property>
     
     <property name="defaultDestination">
        <ref local="destination"/>
     </property>
</bean>

</beans>

 

Spring中JMS的代码如下：

 

package com.easyway.jboss.jms.ptp.spring.service;

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

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

/**
 * Spring中JMS的简单应用
 * @author longgangbai
 *
 */
public class JmsTemplate11 {
	
	private static final Log log=LogFactory.getLog(JmsTemplate11.class);
	
	public static void main(String[] args) {
		ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
		JmsTemplate jt=(JmsTemplate)ctx.getBean("jmsTemplate");
		jt.send(new MessageCreator(){

			@Override
			public Message createMessage(Session session) throws JMSException {
				   return session.createTextMessage("the spring queue /TestQueue");
			}
		});
		log.info("发送信息成功！");
		
	}
}

客户端的配置：applicationContext-jms-receive.xml
