MINA : line is too long 传递大字符串数据

服务端：

// 设置行大小
TextLineCodecFactory lineCodec=new TextLineCodecFactory(Charset.forName("UTF-8"));
lineCodec.setDecoderMaxLineLength(1024*10240); //10M
lineCodec.setEncoderMaxLineLength(1024*10240); //10M
conn.getFilterChain().addLast("codec",new ProtocolCodecFilter(lineCodec));  //行文本解析

  客服端

// 设置行大小
TextLineCodecFactory lineCodec=new TextLineCodecFactory(Charset.forName("UTF-8"));
lineCodec.setDecoderMaxLineLength(1024*10240); //10M
lineCodec.setEncoderMaxLineLength(1024*10240); //10M
conn.getFilterChain().addLast("codec",new ProtocolCodecFilter(lineCodec));  //行文本解析
