我可以为InputStream的read（）函数设置超时吗？ [英] Can I set a timeout for a InputStream's read() function?

问题描述

我从 Socket 获得了 DataInputStream 。有什么办法可以为 dis.read（...）设置超时？目前我产生了一个新线程来进行读取。虽然父线程执行 thread.join（超时）在中断之前等待。我知道nio，但我认为我不想在这一点上重构那么多。谢谢。

I have a DataInputStream that I obtained from a Socket. Is there any way I can set a timeout for dis.read(...)? Currently I spawn a new thread to do the read. While the parent thread does a thread.join(timeout) to wait before interrupting it. I am aware of nio, but I don't think I want to refactor that much at this point. Thanks.

推荐答案

一般不在InputStream上，但你可以使用 Socket #setSoTimeout（int）为套接字本身的所有读操作设置超时。

Not on the InputStream generally, but you can use Socket#setSoTimeout(int) to set a timeout for all read operations on the socket itself.
