前言 # 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 Copy ``@Data public class Receipt { /** * 回执信息 */ String message; /** * 回执类型(`MT1101、MT2101、MT4101、MT8104、MT8105、MT9999`) */ String type; }`` 模拟一个回执生成器 Copy `public class ReceiptBuilder { public static List<Receipt> generateReceiptList(){ //直接模拟一堆回执对象 List<Receipt> receiptList = new ArrayList<>(); receiptList.add(new Receipt("我是MT2101回执喔","MT2101")); receiptList.add(new Receipt("我是MT1101回执喔",
