java线程的三种结束方式

public class ServerThread extends Thread {

    //volatile修饰符用来保证其它线程读取的总是该变量的最新的值

    public volatile boolean exit = false;

    @Override

    public void run() {

        ServerSocket serverSocket = new ServerSocket(8080);

        while(!exit){

            serverSocket.accept(); //阻塞等待客户端消息

            ...

        }

    }

    public static void main(String[] args) {

        ServerThread t = new ServerThread();

        t.start();

        ...

        t.exit = true; //修改标志位，退出线程

    }

}
