Netty Client concurrency

[Liuxianning]

Hi Guys



    There are 2 Modules in my project. I used Netty as channel between them.I used the long connection. In the pipelinefactory of clientside module, the code as follows



     public ChannelPipeline getPipeline()
        throws Exception
    {
        ChannelPipeline pipeline = Channels.pipeline();
        pipeline.addLast("decoder", new MessageDecoder());
        pipeline.addLast("ThreadPoolHandler", executionHandler);
        pipeline.addLast("handler", new ClientHandler());
        return pipeline;
    }



the code get response as follows:



            ClientHandler handler = channel.getPipeline().get(ClientHandler.class);
            return handler.getResponse(request);



My problem is:

 1. is there only one ClientHandler instance even I used ExecutionHandler?

 2. When there is multi-thread send request, all the get response is blocked in the ClientHandler, How should i improve the client concurrency?



Any suggestion is many thanks.



Sincerely

Liuxianning.
