mina服务端,c++客户端交互中中文问题

用mina作为服务端,对方客户端是C++.

报文定义:8位报文长度+报文体

对方发送不包含中文的报文时,一切没有问题,但是一旦带了中文就不对了,

在网上看了,说是要字符编码转换 然后也设置了acceptor.getFilterChain().addLast("codec"new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("GBK"))));

本人菜鸟新手,请问这个问题怎么解决,是不是要自己写个解码器?

提示错误

对方C++放过来应该是使用GBK编码,java在解析为字符串的时候要通过编码方式,如果直接获取C++发送的字符串肯定是不行的,而且java的字符串是unicode编码,需要进行转换。网上很多。。

刚解除mina不久,网上太多,但是具体不懂哪个应该是我要得,能否给个链接?万分感谢
