Smooks EDI转XML报错：找不到d03b-mapping的Jar包依赖

运行代码时出现以下错误：

Failed to locate jar file for EDI Mapping Model URN 'org.milyn.edi.unedifact:d03b-mapping:1.7.1.0'. Jar must be available on classpath.

public class Main {

        //Smooks smooks = new Smooks("smooks-config.xml");

            smooks.filterSource(new StreamSource(new FileInputStream("to-xml/apis.txt")), new StreamResult(writer));

            return writer.toString();

问题出在依赖配置不匹配，具体修正点如下：

1. 添加对应版本的d03b映射依赖
   代码中指定的URN是urn:org.milyn.edi.unedifact:d03b-mapping:1.7.1.0，但当前pom.xml中缺少d03b-mapping依赖，且现有映射依赖版本为1.4，与URN中的版本不匹配。需要添加以下依赖：

   <dependency>
       <groupId>org.milyn.edi.unedifact</groupId>
       <artifactId>d03b-mapping</artifactId>
       <version>1.7.1</version>
   </dependency>
   

2. 升级Smooks核心依赖版本
   当前使用的milyn-smooks-all和milyn-smooks-edi版本为1.4，与映射模型版本1.7.1.0不兼容，需要升级到对应版本：

   <!-- Smooks核心 -->
   <dependency>
       <groupId>org.milyn</groupId>
       <artifactId>milyn-smooks-all</artifactId>
       <version>1.7.1</version>
   </dependency>
   
   <!-- Smooks EDI Cartridge -->
   <dependency>
       <groupId>org.milyn</groupId>
       <artifactId>milyn-smooks-edi</artifactId>
       <version>1.7.1</version>
       <scope>compile</scope>
   </dependency>
   

3. 清理冲突依赖
   移除pom.xml中注释掉的旧版本EDI依赖，以及版本不匹配的milyn-edisax-parser（1.6版本），确保所有Smooks相关依赖版本一致，避免版本冲突。

修改完成后，执行mvn clean install更新依赖，重新运行代码即可解决找不到Jar包的问题。
