好的，我的工作方式可以更直接地解决OP的问题。
请继续阅读简短的答案，以获取有关我如何使用此线程的示例。
简短答案：
ServerSocket myServer;
Socket clientSocket;
try {
myServer = new ServerSocket(port)
myServer.setSoTimeout(2000);
//YOU MUST DO THIS ANYTIME TO ASSIGN new ServerSocket() to myServer‼!
clientSocket = myServer.accept();
//In this case, after 2 seconds the below interruption will be thrown
}
catch (java.io.InterruptedIOException e) {
/* This is where you handle the timeout. THIS WILL NOT stop
the running of your code unless you issue a break; so you
can do whatever you need to do here to handle whatever you
want to happen when the timeout occurs.
*/
}
现实世界的例子：
在此示例中，我有一个ServerSocket等待线程内的连接。关闭应用程序时，我想以干净的方式关闭线程（更具体地说是套接字），然后再关闭应用程序，因此我在ServerSocket上使用.setSoTimeout（），然后使用抛出的中断超时后检查并查看父级是否正在尝试关闭线程。如果是这样，那么我设置关闭套接字，然后设置一个指示线程已完成的标志，然后退出Threads循环并返回null。
package MyServer;
import javafx.concurrent.Task;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketException;
import javafx.concurrent.Task;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketException;
public class Server {
public Server (int port) {this.port = port;}
private boolean threadDone = false;
private boolean threadInterrupted = false;
private boolean threadRunning = false;
private ServerSocket myServer = null;
private Socket clientSocket = null;
private Thread serverThread = null;;
private int port;
private static final int SO_TIMEOUT = 5000; //5 seconds
public void startServer() {
if (!threadRunning) {
serverThread = new Thread(thisServerTask);
serverThread.setDaemon(true);
serverThread.start();
}
}
public void stopServer() {
if (threadRunning) {
threadInterrupted = true;
while (!threadDone) {
//We are just waiting for the timeout to exception happen
}
if (threadDone) {threadRunning = false;}
}
}
public boolean isRunning() {return threadRunning;}
private Task<Void> thisServerTask = new Task <Void>() {
@Override public Void call() throws InterruptedException {
threadRunning = true;
try {
myServer = new ServerSocket(port);
myServer.setSoTimeout(SO_TIMEOUT);
clientSocket = new Socket();
} catch (IOException e) {
e.printStackTrace();
}
while(true) {
try {
clientSocket = myServer.accept();
}
catch (java.io.InterruptedIOException e) {
if (threadInterrupted) {
try { clientSocket.close(); } //This is the clean exit I'm after.
catch (IOException e1) { e1.printStackTrace(); }
threadDone = true;
break;
}
} catch (SocketException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
};
}
然后，在我的Controller类中……（我只会显示相关代码，根据需要将其处理为您自己的代码）
public class Controller {
Server server = null;
private static final int port = 10000;
private void stopTheServer() {
server.stopServer();
while (server.isRunning() {
//We just wait for the server service to stop.
}
}
@FXML private void initialize() {
Platform.runLater(()-> {
server = new Server(port);
server.startServer();
Stage stage = (Stage) serverStatusLabel.getScene().getWindow();
stage.setOnCloseRequest(event->stopTheServer());
});
}
}
我希望这可以帮助某人。
