<h1>前言 </h1>
物流行业中，通常会涉及到EDI报文(XML格式文件)传输和回执接收，每发送一份EDI报文，后续都会收到与之关联的回执（标识该数据在第三方系统中的流转状态）。
这里枚举几种回执类型：MT1101、MT2101、MT4101、MT8104、MT8105、MT9999，系统在收到不同的回执报文后，会执行对应的业务逻辑处理。当然，实际业务场景并没有那么笼统，这里以回执处理为演示案例
模拟一个回执类
<pre class="blockcode"><code class="language-go">@Data
public class Receipt {

/**
* 回执信息
*/
