TCP套接字的连接池和多线程？

Question

I have a java application(say A) which communicate with an application(say B) via TCP Socket. My java application is multithreaded, can handle up to 100 threads. To communicate between A --> B we have 10 sockets.

Challenges -

1. Connection Pooling - need connection pooling mechanism to handle n(say 100) number of thread(of application A), communicating to application B via x(say 10) number of TCP Socket.

2. Multithreading - How can two thread access same socket send the request one by one and get back the response mapped to appropriate thread.

3. Multiple request - Is it possible that two thread can send the request on single socket simultaneously .

Can we over come this challenge via any framework? Is it possible? I heard that Spring Integration/ApacheCamel/Local MQ can resolve this solutions. Any examples.

Answer 1

With Spring Integration:

1. CachingClientConnectionFactory
2. TcpOutboundGateway (with CachingClientConnectionFactory ).
3. Collaborating Outbound and Inbound Channel Adapters .

But you have to do your own request/reply collaboration (usually based on something in the message); the replies may not come back in the order they were sent. Since there is no standard way to perform that collaboration, the framework doesn't support it itself.

Answer 2

I was able to resolve the problem stated in question via jPOS.

jPOS can do multiplexing. It uses ISOMessage field 11 and 41 for matching the request and response.

jPOS also providing pooling mechanism.
