关于RemotingClient异步请求后钩子函数的执行问题

[FantasyChen-DH]

在我最近阅读remoting包下的NettyRemotingClient和NettyRemotingAbstract时，发现在进行异步请求后，并不会对RPCHook进行进一步调用。我对此还使用test包下的RemotingServerTest进行测试：
` @test
public void testInvokeAsync() throws InterruptedException, RemotingConnectException,
RemotingTimeoutException, RemotingTooMuchRequestException, RemotingSendRequestException {

    final CountDownLatch latch = new CountDownLatch(1);
    RPCHook rpcHook = new RPCHook() {
        @Override
        public void doBeforeRequest(String remoteAddr, RemotingCommand request) {
            System.out.println("send Request");
        }

        @Override
        public void doAfterResponse(String remoteAddr, RemotingCommand request,
                                    RemotingCommand response) {
            System.out.println("after response");
        }
    };
    remotingClient.registerRPCHook(rpcHook);
    RemotingCommand request = RemotingCommand.createRequestCommand(0, null);
    request.setRemark("messi");
    remotingClient.invokeAsync("localhost:8888", request, 1000 * 3, new InvokeCallback() {
        @Override
        public void operationComplete(ResponseFuture responseFuture) {
            assertTrue(responseFuture != null);

// assertThat(responseFuture.getResponseCommand().getLanguage()).isEqualTo(LanguageCode.JAVA);
// assertThat(responseFuture.getResponseCommand().getExtFields()).hasSize(2);
System.out.println("收到回应");
latch.countDown();
}
});
latch.await();

}

}`

但未执行RPCHook中的doAfterResponse方法，所以对此有疑惑，这个钩子函数会在何时才会执行还是说异步请求无需进行，感谢解答！

这里好像有一个相关issue #1709, /cc @aaron-ai

看样子是的 但是并没有回应 是异步请求不需要做钩子函数的After操作吗

[aaron-ai]

@FantasyChen-DH I think it is a bug rather than a feature, the execution of hook should not depend on the sync/async way of the invocation. It will be great if you could fix it.

OK I would like to fix it
