Java：如何使用“尝试资源”设置套接字超时

Question

I want to set a socket connection timeout. I know that I can set it using the connect method but this is my code:

try(Socket socket = new Socket(InetAddress.getByName(ip), port);
    BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));
    PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF-8")), true)){

Answer 1

It's not really clear from your question where you are stuck, but you can just keep using the connect method:

int timeout = 25000;
try (Socket socket = new Socket()) {
    socket.connect(new InetSocketAddress("abc", 123), timeout);
    try (BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));
         PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF-8")), true)) {

    }
}

Answer 2

try(Socket socket = new Socket(InetAddress.getByName(ip), port)) {
    socket.connect(adress, timeout);
} catch (Throwable t) {
    handleException(t);
}
