Spring JMS的开发应用--自定义消息转换器的使用（四）

          在Spring JMS、中可以通过实现MessageConverter自定义自己的消息转换器实现消息的转换。在Spring 的JMS1.1有SimpleMessageConverter实现基本的消息转换，在JMS1.02中SimpleMessageConverter102实现消息的转换的工作。

 

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

public class SMS  implements java.io.Serializable{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String username;
	private String message;
	
	public SMS(){
		
	}
	public SMS(String username,String message){
		this.username=username;
		this.message=message;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getMessage() {
		return message;
	}
	public void setMessage(String message) {
		this.message = message;
	}
	
	
	

}

 

 

消息转换器：

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

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

import org.springframework.jms.support.converter.MessageConversionException;
import org.springframework.jms.support.converter.MessageConverter;

import com.easyway.jboss.jms.ptp.service.SMS;
/**
 * 自定义消息转换器MessageConverter实现
 * 在JmsTemplate提供了各种send方法，供发送消息使用，其中JmsTemplate中的
 * convertAndSend和receiveAndConvert方法能够借助于MessageConverter接口
 * 实现消息做相应的转换。
 * JMS1.1中SimpleMessageConverter实现String与TextMessage,等之间的转换
 * @author longgangbai

 */
public class SMSConverter implements MessageConverter {

	@Override
	public Object fromMessage(Message message) throws JMSException,
			MessageConversionException {
		 SMS sms=new SMS();
		 MapMessage  mapmessage= (MapMessage  )message;
		 sms.setMessage(mapmessage.getString("message"));
		 sms.setUsername(mapmessage.getString("username"));
		return sms;
	}

	@Override
	public Message toMessage(Object object, Session session)
			throws JMSException, MessageConversionException {
		 SMS sms=(SMS)object;
		 MapMessage  mapmessage=session.createMapMessage();
		 mapmessage.setString("username", sms.getUsername());
		 mapmessage.setString("message", sms.getMessage());
		 return mapmessage;
	}

}

	public static void main(String[] args) {
		ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext-cjms-receive.xml");
		JmsTemplate jt=(JmsTemplate)ctx.getBean("jmsTemplate");
		SMS sms=(SMS)jt.receiveAndConvert();
		System.out.println("username:"+sms.getUsername());
		System.out.println("message:"+sms.getMessage());
