服务端的接收进程一样也要放在while(true)循环中才能持续不断的接收客户端发来的消息。

private static class ServerInputThread extends Thread {

		private Socket socket;

		public ServerInputThread(Socket socket) {
			// TODO Auto-generated constructor stub
			this.socket = socket;
		}

		public void run() {
			try {
				InputStream inputstream = socket.getInputStream();
				while (true) {
				
				byte [] buffer = new byte [1024];
				
				int length = inputstream.read(buffer);
				
				String information = new String(buffer,0,length);
				
				System.out.println(information);
				}
				
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			

		}
