关于socket通信的问题？

bout.flush();
你忘记这句了
class MyThread extends Thread {
    @Override
    public void run() {
        try {
             //初始化相关socket IO 
                bin = new BufferedInputStream(SocketService.tcp_socket.getInputStream());
                bout = new BufferedOutputStream(SocketService.tcp_socket.getOutputStream());
                byte[] data = {1,2,3,4,5};
                bout.write(data);
                bout.flush();
                System.out.print("send success!");
        //    getTemp_Sun_Hum();//获得温度、湿度、光照信息
 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
