我几乎没有从 WSO2 ESB 开始，需要创建一个方案，允许我从通过 VFS（已启用）获得的 .edi 文件（96a）将其转换为 XML ......为此，我正在使用 Smooks 和UN / EDIFACT 执行解析。执行时会出现以下错误 WSO2：

Smooks的配置是：

<?xml version="1.0"?>    
<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"
                       xmlns:unedifact="http://www.milyn.org/xsd/smooks/unedifact-1.4.xsd">
    <unedifact:reader mappingModel="urn:org.milyn.edi.unedifact:d96a-mapping:*" />
</smooks-resource-list>

我在 Java 应用程序中使用过同样的配置，而且我工作得很好。

此外，除了创建 CLASSPATH 甚至 build-classpath-directory 命令之外，我还尝试在 WSO2 中的 dropins 和 lib 目录中手动添加依赖项，但没有成功。

同志们，经过多次搜索和询问，我设法找到了一个部分但功能齐全的解决方案。首先，您必须正确识别将读取EDIFACT映射的路径，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="smooks">
  <smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" xmlns:unedifact="http://www.milyn.org/xsd/smooks/unedifact-1.4.xsd">
    <unedifact:reader mappingModel="//opt//wso2//wso2esb-4.8.1//repository//components//lib//org.milyn.edi.unedifact.d96a-mapping_1.4.jar"/>
  </smooks-resource-list>
</localEntry>

有了这个，您已经可以读取EDIFACT文件，但有些包含任何不一致，因为只读取一个跟踪，但不读取多个跟踪，要修复您必须删除第一行：

UNB+UNOA:2+925485K200:8+7808800024232:1+150526:0108+168'
...

一种快速简便的方法是创建一个自定义调解器，它将“ UNB ”转换为“ ' ”并使用正则表达式删除其中的所有内容：

UNB[\\d|\\D|\\+|\\:]*'

有了这个，我们实现了在 WSO2ESB 中读取传入 EDIFACT 的多个跟踪。
