一、代码部分

public static void main(String[] args) throws Exception{
        ExecutorService pool = Executors.newCachedThreadPool();
        ServerSocket serverSocket = new ServerSocket(6666);
        while (true) {
            Socket socket = serverSocket.accept();
            pool.execute(new Runnable() {
                @Override
                public void run() {
                    handler(socket);
                }
            });
        }
    }

    private static void handler(Socket socket) {
        try {
            InputStream inputStream = socket.getInputStream();
            byte[] bytes = new byte[1024];
            while (true) {
                int read = inputStream.read(bytes);
                if (read != -1) {
                    System.out.println("收到信息：" + new String(bytes, 0, read));
                } else {
                    break;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                socket.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
