smooks数据转换:java to edi
Smooks是一种java的开源框架，可以进行edi to java、java to edi、xml to edi、edi to xml等等转换操作。
milyn-smooks-edi是milyn-smooks-all的一个子模块，处理edi和java之间的转换
1 <dependency> 2 <groupId>org.milyn</groupId> 3 <artifactId>milyn-smooks-all</artifactId> 4 <version>1.7.0</version> 5 </dependency> 6 或者 7 <dependency> 8 <groupId>org.milyn</groupId> 9 <artifactId>milyn-smooks-edi</artifactId> 10 <version>1.7.0</version> 11 </dependency>
在Smooks的官方文档有相关edi to java的案例，但是java to edi的例子非常少，本篇博客主要提供一些java to edi的方法。
EDI，全称 Electronic Data Interchange，译名：电子数据交换。有很多的标准，本文主要转化的是Intrra D99b UN/Edifacrt 类型的国际标准的EDI报文

d99b-mapping包解决了edi to java，d99b-binding包解决了java to edi.
https://mvnrepository.com/artifact/org.milyn.edi.unedifact 或者 https://www.pangugle.com/lib/maven/group/org.milyn.edi.unedifact.html 几乎有所有类型的国家标准的edi类型报文和java之间的映射。

2020-06-05补充信息，
1. 所需文件：https://files.cnblogs.com/files/zmngc/IFTMIN.zip
2. 计算报文行数：
/** * 计算报文有多少行 * * @param message 报文内容 * @return */ public static Integer messageLine(String message) { if (StringUtils.isEmpty(message)) { return 0; } message = message.trim(); String[] array = message.split("'"); String[] array2 = message.split("\\?'"); if (array2.length > 0) { return array.length - array2.length + 1; } else { return array.length; } }
