java - Timeout for SocketChannel doesn't work

Question

I want to use a SocketChannel and to have a timeout for its read/write methods. I've tried to set a timeout for the Socket that owns my SocketChannel like this:

channel.socket().setSoTimeout(TIMEOUT);

but that doesn't work. Is there any other solution?

Answer 1

According to this article, SocketChannel will not timeout for its read operation but you can get this effect from reading from the channel in another way.

SocketChannel socketChannel;
socketChannel.socket().setSocketTimeout(500);
InputStream inStream = socketChannel.socket().getInputStream();
ReadableByteChannel wrappedChannel = Channels.newChannel(inStream);

reading from the wrappedChannel will timeout according to the socketTimeOut you have set.
