javax.jms Class QueueRequestor

java.lang.Object
  javax.jms.QueueRequestor

public class QueueRequestor
extends Object

The QueueRequestor helper class simplifies making service requests.

The QueueRequestor constructor is given a non-transacted QueueSession and a destination Queue. It creates a TemporaryQueue for the responses and provides a request method that sends the request message and waits for its reply.

This is a basic request/reply abstraction that should be sufficient for most uses. JMS providers and clients are free to create more sophisticated versions.

构造器详细信息

QueueRequestor

public QueueRequestor(QueueSession session,
                      Queue queue)
               throws JMSException

Constructor for the QueueRequestor class.

This implementation assumes the session parameter to be non-transacted, with a delivery mode of either AUTO_ACKNOWLEDGE or DUPS_OK_ACKNOWLEDGE.

参数:: session - the QueueSession the queue belongs to; queue - the queue to perform the request/reply call on
抛出异常:: JMSException - if the JMS provider fails to create the QueueRequestor due to some internal error.; InvalidDestinationException - if an invalid queue is specified.

方法详细信息

request

public Message request(Message message)
                throws JMSException

Sends a request and waits for a reply. The temporary queue is used for the JMSReplyTo destination, and only one reply per request is expected.

参数:: message - the message to send
返回:: the reply message
抛出异常:: JMSException - if the JMS provider fails to complete the request due to some internal error.

close

public void close()
           throws JMSException

Closes the QueueRequestor and its session.

Since a provider may allocate some resources on behalf of a QueueRequestor outside the Java virtual machine, clients should close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

Note that this method closes the QueueSession object passed to the QueueRequestor constructor.

抛出异常:: JMSException - if the JMS provider fails to close the QueueRequestor due to some internal error.
