Question

我有通过套接字发送消息和接收答案的方法。如何放置计时器，如果没有答案，例如1秒放信息超时？

public boolean SendForceMessage(final ForceMessageTCP message) {
    boolean result = true;
    System.out.println("******************SendForceMessage**********************************");
    new Thread() {
        public void run() {
            try {
                System.out.println("IPADDRESS="+ipAddress);
                System.out.println("PORT="+port);
                System.out.println("Is reachable="+Ping());

                for(int i=0;i<message.ToBytes().length;i++)
                    System.out.println("FRAGMENT["+i+"]="+message.ToBytes()[i]);

                socket = new Socket(ipAddress, port);
                OutputStream socketOutputStream = (OutputStream) socket
                        .getOutputStream();
                socketOutputStream.write(message.ToBytes());

                InputStream socketInputStream=(InputStream)socket.getInputStream();
                byte[] buffer=new byte[256];
                int numberReceived=socketInputStream.read(buffer);
                if(numberReceived!=-1)
                    new FDResponseMessage(buffer);


                socket.close();
            } catch (UnknownHostException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }.start();

    return result;
}

忘记套接字选项，请查看：http://download.oracle.com/javase/1.4.2/docs/api/java/net/Socket.html#setSoTimeout(int）

基本上您设置了 SO ，因此您对 read（）的调用只会阻止您指定的时间
