How to set write timeout on Socket

Question

In java, Socket has a method setSoTimeout that can be used to specify the reading timeout, but there is no method to specify the writing timeout

When I　searched google, a lot of responses like "use nio and selectors", it looks that SocketChannel provides the way to specify the writing timeout, I brief the code of this class, but I still didn't find out how to do it.

Could someone show some code or some guide? Thanks

Thanks @PrashantPuri. yes, the link has mentioned `use nio and selectors`,but didn't say how. — Tom, Sep 19 '17 at 05:29
He most certainly did say how, or rather provided a [link](http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4031100) to how. — user207421, Sep 19 '17 at 05:32
@EJP which link, sorry I didn't find the link. http://bugs.java.com/bugdatabase/view_bug.do?bug_id=4031100? — Tom, Sep 19 '17 at 05:46
@Tom That link. The one he provided. The one I provided. The one you put in your most recent comment. — user207421, Sep 19 '17 at 09:58

One possible way to mitigate the lack of a timeout option on a write call is to simply just set the SO_SNDBUF size via Socket.setSendBuffer to something very high. This will allow subsequent calls for writing to avoid blocking unless the pipe to the remote side gets backed up. If possible, structure your protocol such that you wait for some sort of response to data already sent before sending more data. That way, you won't ever exceed the send buffer.

YMMV.
