Can I set a timeout for a InputStream's read() function?
提问by Zombies
I have a DataInputStreamthat 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.
我有一个DataInputStream从Socket. 有什么办法可以设置超时dis.read(...)吗？目前我生成了一个新线程来进行读取。而父线程thread.join(timeout)在中断它之前会等待。我知道 nio，但我认为此时我不想重构那么多。谢谢。

Not on the InputStream generally, but you can use Socket#setSoTimeout(int)to set a timeout for all read operations on the socket itself.
通常不在 InputStream 上，但您可以使用它Socket#setSoTimeout(int)为套接字本身的所有读取操作设置超时。
