我有一个实现Runnable
接口的 UDP 服务器类。我在线程中启动它。问题是我无法阻止它。即使在 Debug 中,它也会停止在pt.join()
方法上。
这是我的服务器类
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.SocketException;
public class Network implements Runnable {
final int port = 6789;
DatagramSocket socket;
byte[] input = new byte[1024];
byte[] output = new byte[1024];
public Network() throws SocketException{
socket = new DatagramSocket(6789);
}
@Override
public void run() {
while(true){
DatagramPacket pack = new DatagramPacket(input,input.length);
try {
socket.receive(pack);
} catch (IOException e) {
e.printStackTrace();
}
input = pack.getData();
System.out.println(new String(input));
output = "Server answer".getBytes();
DatagramPacket sendpack = new DatagramPacket(output,output.length,pack.getAddress(),pack.getPort());
try {
socket.send(sendpack);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
这是主要课程
public class Main {
static Network network = null;
public static void main(String[] args) throws IOException{
network = new Network();
System.out.println("Try to start server");
Thread pt = new Thread(network);
pt.start();
pt.interrupt();
try {
pt.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Stop server");
}
}
如何停止服务器?
