从JMSBytesMessage读取数据_jms根据messageid读取报文-优快云博客

本文介绍了一种使用Java实现的QPID消息注册及处理方法。通过创建QueueListener并设置URL、队列名称和处理器，实现了从指定QPID队列接收消息的功能。文中详细展示了如何解析接收到的消息内容。

最近做一个项目，需要从QPID消息中获取信息。

注册QPID消息

QueuelistenerManager queuelistenerManager = new QueuelistenerManager(true);

QueueListener queueListener = new QueueListener();
String url = “amqp://guest:guest@clientid/test?brokerlist='tcp://192.168.2.1:5772'”;
queueListener.setUrl(url);
queueListener.setQueueName("QPID_QUEUE_NAME");
MyProcessor myProcessor = new MyProcessor ();
queueListener.setProcessor(myProcessor );
queuelistenerManager.addListener(queueListener);

public class MyProcessor implements MessageProcessor
{

@Override
public void processMessage(Message message)
{
System.out.println("in process!!!!");
JMSBytesMessage bytesMessage = (JMSBytesMessage) message;

try
{
ByteBuffer bb = bytesMessage.getData();
int len = bb.capacity();
byte[] msgbytes = new byte[len];
bb.get(msgbytes, 0, len);//这里需要将字节信息节取出来，然后根据字段格式进行截取。

//INT32 code1;
int code1= byte2Int(msgbytes, offset, ByteOrder.LITTLE_ENDIAN);

}catch(Exception e){

}

public static int byte2Int(byte[] bytes, int offset, ByteOrder order)
{
ByteBuffer buffer = ByteBuffer.wrap(bytes, offset, 4);
buffer.order(order);
return buffer.getInt();
}

}
