connect

publicvoidconnect(SocketAddress endpoint,

inttimeout)

throwsIOException

Connectsthissocket to the server with a specified timeout value.

A timeout of zero is interpreted as an infinite timeout.

The connection will then block until established or an error occurs.

Parameters:

endpoint - the SocketAddress

timeout - the timeout value to be used in milliseconds.

Throws:

IOException -ifan error occurs during the connection

SocketTimeoutException -iftimeout expires before connecting

IllegalBlockingModeException -

ifthissocket has an associated channel, and the channel is in non-blocking mode

IllegalArgumentException -

ifendpoint isnullor is a SocketAddress subclass not supported bythissocket

connect

public void connect(SocketAddress endpoint,

int timeout)

throws IOException

Connects this socket to the server with a specified timeout value.

A timeout of zero is interpreted as an infinite timeout.

The connection will then block until established or an error occurs.

Parameters:

endpoint - the SocketAddress

timeout - the timeout value to be used in milliseconds.

Throws:

IOException - if an error occurs during the connection

SocketTimeoutException - if timeout expires before connecting

IllegalBlockingModeException -

if this socket has an associated channel, and the channel is in non-blocking mode

IllegalArgumentException -

if endpoint is null or is a SocketAddress subclass not supported by this socket

Since:

1.4

选自java API :java.net.Socket

Socket socket = new Socket();

SocketAddress address = new InetSocketAddress("127.0.0.1", 8080);

try {

socket.connect(address, 60000);

SocketTimeoutException

} catch (IOException e) {

e.printStackTrace();

}

使用Socket.connect(SocketAddress sa, int timeout)方法。timeout为毫秒数，为0则永不超时(Socket默认也是如此)。如果到时间，仍然没有连接成功，则抛出SocketTimeoutException，在java.net包中。
