Answer 3

我现在已经明白我的问题在哪里了！谢谢各位的参与。可是虽然知道了问题在哪里，我还是找不到解决的方法。现在我的问题是，怎样做才能停止一个已经开始accept()的ServerSocket.
比如说
LocalServerSocket.accept();之后当前的线程就被block了，在这个时候，如果我不想再继续
开这个server,我该怎样关闭呢？我曾经试过LocalServerSocket.close(),但是这样会抛出IOException.各位大大，有什么办法吗？谢谢！！！           
                                

Answer 4

这个应该很好办吧！你的LocalServerSocket是在主线程吧？
while(true) {
  Socket s=LocalServerSocket.accept();
}
你说的你的线程被block后，你不想要这个Server了？你说的是s还是LocalServerSocket？如果是s呀，我就建议你为打开的服务建立一个线程，把这个线程关闭就可以了.

Answer 5

我说的是LocalServerSocket,我要关闭的是主线程里的ServerSocket.可是我每次调用LocalServerSocket.close(),就会抛出IO异常。另外我试了一下sleep（），可是这下连我的主线程也没反映了。大家再帮帮忙吧！

Answer 6

还是用设置标志位关闭吧：
设置class ServerThread extends Thread{
private boolean stoped=false;
.......
         public void stop(){stoped=true};//添加方法
public void run(){
try{
LocalServerSocket=new ServerSocket(PORT);
Tcpserver.clear();
                              ...... while(!stoped){//监测标志位
//spawn a child thread
new ClientThread(LocalServerSocket.accept());
}
}
catch(IOException ioe){
messager.printerr("IO Exception Detected:"+ioe.getMessage());
messager.printerr("The Application is now terminated.");
System.exit(1);
}finally{
                      LocalServerSocket.close();//加入
                  }
}
这样你就可以在main()里调用ServerSocket.stop()来终止了

sorry, I am in school now and here got no IME,so I have to use english.suppose the program run up to the line:
        new ClientThread(LocalServerSocket.accept());
and the thread has been blocked due to the call to accept();
so the program is just stop there and never check the flag, and the flag got no use.
so any other ideas? thanks anyway.

Answer 8

finally,I solve it!using close and catch the SocketException.
very happy now. thanks~~~!
