Java：如何使用"try with resources"设置套接字超时

Question

我想设置套接字连接超时。我知道我可以使用连接方法设置它，但这是我的代码：

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

从你的问题中还不清楚你卡在哪里，但你可以继续使用 connect 方法：

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);
}
