netty中 解决服务器到客户端传输数据 中文乱码问题

//编码格式
arg0.pipeline().addLast(new StringEncoder(Charset.forName("GBK")));
//解码格式
arg0.pipeline().addLast(new StringDecoder(Charset.forName("UTF-8")));

ch.pipeline().addLast(new StringEncoder(Charset.forName("UTF-8")));
                            ch.pipeline().addLast(new StringDecoder(Charset.forName("GBK")));

这有一个编码转换的方法

  String strGBK = URLEncoder.encode(str, "GBK");  
            System.out.println(strGBK);  
            String strUTF8 = URLDecoder.decode(str, "UTF-8");  
            System.out.println(strUTF8);
