Spring整合ActiveMQ-序列化的 Java对象

[size=medium]JMS定义了五种不同的消息正文格式，以及调用的消息类型，允许你发送并接收以一些不同形式的数据，提供现有消息格式的一些级别的兼容性。

· StreamMessage -- Java原始值的数据流

· MapMessage--一套名称-值对

· TextMessage--一个字符串对象

· ObjectMessage--一个序列化的 Java对象

· BytesMessage--一个未解释字节的数据流

1.发送者

package com.tech.gps.util;
 
import org.springframework.jms.core.JmsTemplate;
 
import com.tech.gps.model.Bus;
 
  
public class MessageSender {  
     
    private JmsTemplate jmsTemplate;  
   
    public void sendMessage(Bus bus){  
        
        jmsTemplate.convertAndSend(bus);  
    }
 
    public JmsTemplate getJmsTemplate() {
        return jmsTemplate;
    }
 
    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }  
  
}  

2.消息转化

package com.tech.gps.util;
 
import java.io.Serializable;
 
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.ObjectMessage;
import javax.jms.Session;
import javax.jms.TopicPublisher;
 
import org.apache.activemq.command.ActiveMQObjectMessage;
import org.springframework.jms.support.converter.MessageConversionException;
import org.springframework.jms.support.converter.MessageConverter;
 
import com.tech.gps.model.Bus;
 
public class MessageConvertForSys implements MessageConverter {  
     
    public Message toMessage(Object object, Session session)  
            throws JMSException, MessageConversionException {  
         
        System.out.println("sendMessage:"+object.toString());  
        ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage();
        msg.setObject((Serializable) object);
        return msg; 
    }  
      
    public Object fromMessage(Message message) throws JMSException,  
            MessageConversionException {  
          
         Bus bus = null;
         if(message instanceof ActiveMQObjectMessage){
             ActiveMQObjectMessage aMsg = (ActiveMQObjectMessage) message; 
             bus=(Bus) aMsg.getObject();
         }
        return bus;  
    }
  
} 

3.接受消息

package com.tech.gps.util;
 
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
 
import com.tech.gps.model.Bus;
 
  
 
public class MessageReceiver implements MessageListener {  
       
    public void onMessage(Message m) {  
         
         Bus bus= new Bus();
         if(m instanceof ObjectMessage){
             ObjectMessage objectMessage=(ObjectMessage) m;
         try {
              
             bus=(Bus) objectMessage.getObject();
             String busNo = bus.getBusNO();
             String xpoint = bus.getxPoint();
             String yPoint = bus.getyPoint();
             System.out.println("车编号："+busNo+"  X："+xpoint+"  Y："+yPoint);
         } catch (JMSException e) {
             e.printStackTrace();
         }
         }
          
    }
 
      
}
