Jersey ChunkedOutput-如何检测客户端断开连接？

Question

Using curl as the client, jersey and grizzly on the server side, I can not get server to detect clients disconnections. Even in the case when the server write message to the client the ChunkedOutput.write succeeds.

Is there a configuration either in grizzly or in jersey that can make writes to the chunked output fail?

Answer 1

Seems like when using Grizzly - Worker-thread IOStrategy the ChunkedOutput object (Jersey object) does not recognise clients disconnects immediately.

I ended up using Same-thread IOStrategy. This might not be the best solution for all apps, but for mine it is great.

NetworkListener listener = new NetworkListener("grizzly2", host, port);
listener.getTransport().setIOStrategy(SameThreadIOStrategy.getInstance());

I also tried using the Worker-thread IOStrategy and lowering the write buffer:

NetworkListener listener = new NetworkListener("grizzly2", host, port);
listener.getTransport().setWriteBufferSize(bufferSize);

This has also worked when the bufferSize was smaller then the actual messages sent.
