分享Java写的TCP/IP通讯的问题：
用Java的Socket类写TCP/IP通讯，用read()函数时要阻塞。有没有什么方法，让read()函数在一定的时间内没有接受到数据就返回？

插一句，用 jdk 1.4 的new io吧，如果你需要支持大规模的并发连接（500-1000）的话。

setSoTimeout
public void setSoTimeout(int timeout)
throws SocketException
Enable/disable SO_TIMEOUT with the specified timeout, in milliseconds. With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.
Parameters:
timeout - the specified timeout, in milliseconds.
Throws:
SocketException - if there is an error in the underlying protocol, such as a TCP error.
Since:
JDK 1.1

用Socket.setSoTimeout来设置超时。
