Tibco-Rv：如何使用TibRv-Java API建立双向通信

Question

使用TibRvdTransport->send(msg)发送Tbrv msg时是否可能有回调，并且在订户中我们可以发送回复吗？

我想从发布者和接收者发送“ Hello”，并且应该接收并发送“ Hi”回复。 发布者必须在回调中获取此“ Hi”并进行打印。

发布者=>

TibrvRvdTrasport transport= new TibrvRvdTrasport ("12000","127.0.0.1","6000");
TibrvMsg tibMsg = new TibrvMsg();
tibMsg.add("msg" "hello");
tibMsg.setSendSubject(subject);
transport.send(tibMsg);

订阅者=>

listener = new TibRvListener(tibRvQueue, new TibRvMsgCallback(){
    @Override
    public void onMsg(TibRvListener listener,TibRvMsg msg){
        try{
            -----//sendReply("Hi")
        }
        catch(Exception e){

        }
    }, 
    new TibRvdTransport("12000","127.0.0.1","6000")),subject,null);

当然，这是一种方法。 通常，您创建一个私人“收件箱”主题，该主题用作原始请求的回复主题。 该“收件箱”只是一个简单的唯一字符串。 它可以是任何东西（也可以是“ REPLY”），但是在大多数情况下拥有一个唯一的东西很有用。

发件人方面：

  Tibrv.open(Tibrv.IMPL_NATIVE);
  TibrvRvdTransport transport = new TibrvRvdTransport ("12000","127.0.0.1","6000");
  TibrvMsg request = new TibrvMsg();
  request.add("msg", "hello ");
  request.setSendSubject("TEST");
  request.setReplySubject(transport.createInbox()); // the subject we expect a reply on

  System.err.println("sending request: " + request);
  TibrvMsg reply = transport.sendRequest(request, 10*1000); // wait 10 seconds for reply
  System.err.println("received response: " + reply);
  Tibrv.close();

和接收方：

  Tibrv.open(Tibrv.IMPL_NATIVE);
  TibrvRvdTransport transport = new TibrvRvdTransport ("12000","127.0.0.1","6000");

  new TibrvListener( Tibrv.defaultQueue(), new TibrvMsgCallback() {

    @Override
    public void onMsg(TibrvListener listener, TibrvMsg msg)
    {
      try {
        System.err.println("received request: " + msg );
        TibrvMsg reply = new TibrvMsg();
        reply.setSendSubject(msg.getReplySubject()); // send response to the 'reply' subject
        reply.add("response","world!");
        System.err.println("sending response: " + reply );
        transport.send(reply);
      }
      catch (TibrvException e) {
        e.printStackTrace();
      }

    }}, transport, "TEST", null );

  TibrvDispatcher dispatcher = new TibrvDispatcher(Tibrv.defaultQueue());
  Thread.sleep(100*1000);
  dispatcher.destroy();
  Tibrv.close();
