    codec.encode(channel, encodeBuffer, request);
    byte[] bytes = new byte[encodeBuffer.writerIndex()];
    encodeBuffer.readBytes(bytes);
    int len = Bytes.bytes2int(bytes, 12);
    ByteArrayOutputStream out = new ByteArrayOutputStream(1024);
    out.write(bytes, 0, 12);
    /*
     * 填充长度不能低于256，hessian每次默认会从流中读取256个byte.
