比如长度为16 ，从16进制角度看应该是 0x000010,实际返回 0x 30 31 36，暂时不标准不能netty插件自动解包
为了解决长度数据这个问题，引入自定义长度计算 CustomLengthFieldBasedFrameDecoder
查询ups 报警状态 发送 ～00P003STBAA
收到答复 ~00D0330;0;0;0;127;0;271;;30;100;;;;;;;;BB
用了CustomLengthFieldBasedFrameDecoder 后得到 0;0;0;0;127;0;271;;30;100;;;;;;;;
分析结果要用 String[] feildArray = datastr.split(";", 18); 这样不报错，不加第2个参数，得到的实际数组长度只有10
