无法通过Groovy保存Sitecore迁AEM的元数据求助

我们正在将内容从Sitecore迁移至AEM，当前编写的Groovy脚本可创建DitaMap，但存在两个问题：

• 元数据无法保存
• 无法仅保存与topicBody（而非嵌套的conceptBody）关联的元数据

Sitecore内容JSON示例 #

"topicBody": [
{
"itemId": "84dbfa1a",
"itemUrl": "",
"itemName": "Test Defect-Treatment",
"__typename": "TreatmentConcept",
"templateId": "c51297ec",
"pocId": "TXC-20096525",
"conceptBody": [
{
"itemId": "54ceda8a",
"itemName": "Test Defect-Closure",
"templateId": "d1a1f112",
"__typename": "KmSection",
"pocId": "SEC-2009",
"title": "Closure"
},
{
"itemId": "84134c21",
"itemName": "Test Defect-Patient Observation",
"templateId": "d1a1f112",
"__typename": "KmSection",
"pocId": "SEC-2006",
"title": "Observation"
}
],
"title": "Treatment",
"type": "",
"workflowItemManager": "mfad\\ALS07"
},
{
"itemId": "01ffe5c6",
"itemUrl": "",
"itemName": "Test Defect-Patient Considerations",
"__typename": "ConditionPatientConsiderationsConcept",
"templateId": "69265f07",
"pocId": "PTC-20117566",
"conceptBody": [
{
"itemId": "3a4f77ab",
"itemName": "Test Defect-Endocarditis Prophylaxis",
"templateId": "d1a1f112",
"__typename": "KmSection",
"pocId": "SEC-20096528",
"title": "Endocarditis prophylaxis"
}
],
"title": "Patient considerations",
"type": "",
"workflowItemManager": "mfad\\ALS07"
}
],

当前Groovy脚本 #

def createADitaMap(title, topicBody){
    CreateDitaTopic topic = new CreateDitaTopic()
    try {
        def topicBodyItemTitle = title
        def newTopicPath

        if(type == "CPM"){
            JcrUtil.createPath(globalConfigurations.reuseLibraryCpmMaps+"/"+topicBodyItemTitle, JcrResourceConstants.NT_SLING_FOLDER, JcrResourceConstants.NT_SLING_FOLDER, session, true)
            newTopicPath = globalConfigurations.reuseLibraryCpmMaps+"/"+topicBodyItemTitle+"/"+topicBodyItemTitle+".ditamap"
        }else {
            JcrUtil.createPath(globalConfigurations.ameDitaMapBaseFolderPath+"/"+baseFolderForPoc+"/mapsandTopics", JcrResourceConstants.NT_SLING_FOLDER, JcrResourceConstants.NT_SLING_FOLDER, session, true)
            newTopicPath = globalConfigurations.ameDitaMapBaseFolderPath+"/"+baseFolderForPoc+"/mapsandTopics/"+topicBodyItemTitle+".ditamap"
        }

        def lbMapnode = resourceResolver.getResource(newTopicPath)
        if(null == lbMapnode) {
            topic.create(session, title, newTopicPath, globalConfigurations.clinicalKnowledgeditaMapTemplatePath, resourceResolver, true)
            def metadataNode = session.getNode(newTopicPath + "/jcr:content/metadata")
            //out.println "metadataNode for updateDitaMetaDataForAME: ${metadataNode}"
            if (metadataNode != null) {
                metadataNode.setProperty("dc:title", topicBodyItemTitle)
                metadataNode.setProperty("mc:assignedEditor", topicBody.assignedEditor)
                metadataNode.setProperty("mc:PocId", topicBody.pocId)
            }
            
        }
        session.save()
    } catch (NullPointerException npe) { /* Handling transitive API exception. */
        out.println "NullPointer Exception during topic creation in createADitaMap ${npe.getMessage()}"
    }catch (Exception e) {
        out.println "Exception during topic creation in createADitaMap ${e}"
    }
}

解决方案 #

1. 修复元数据无法保存问题 #

• 路径与权限检查：打印newTopicPath + "/jcr:content/metadata"确认路径正确，同时验证session拥有该节点的写入权限。
• 模板属性验证：确认clinicalKnowledgeditaMapTemplatePath模板包含metadata节点，且dc:title、mc:assignedEditor、mc:PocId属性已定义。若属性不存在，需先创建：

  if (!metadataNode.hasProperty("mc:assignedEditor")) {
      metadataNode.setProperty("mc:assignedEditor", "")
  }
  

• 增强异常捕获：在属性赋值代码块中添加异常捕获，定位具体错误：

  if (metadataNode != null) {
      try {
          metadataNode.setProperty("dc:title", topicBodyItemTitle)
          metadataNode.setProperty("mc:assignedEditor", topicBody.workflowItemManager)
          metadataNode.setProperty("mc:PocId", topicBody.pocId)
      } catch (Exception e) {
          out.println "Metadata property set failed: ${e.getMessage()}"
      }
  }
  

• 确认会话保存时机：确保session.save()在所有属性设置完成后执行，未被异常中断。

2. 确保仅保存topicBody层级元数据 #

• 修正字段映射：原脚本中topicBody.assignedEditor对应JSON里的workflowItemManager字段，需改为topicBody.workflowItemManager，否则会因字段不存在导致赋值失败。
• 遍历topicBody数组：从JSON示例看topicBody是数组，需遍历每个元素单独创建DitaMap，调用示例：

  // 解析Sitecore JSON得到topicBody数组
  def topicBodyList = // 你的JSON解析逻辑
  topicBodyList.each { topicItem ->
      createADitaMap(topicItem.title, topicItem)
  }
  

• 隔离conceptBody：脚本中仅使用传入的topicItem的pocId、workflowItemManager等顶层属性，不访问conceptBody嵌套内容。

3. 脚本优化建议 #

• 简化路径拼接：使用GString替代字符串拼接，减少错误：

  newTopicPath = "${globalConfigurations.reuseLibraryCpmMaps}/${topicBodyItemTitle}/${topicBodyItemTitle}.ditamap"
  

• 父节点检查：创建文件夹前先检查是否存在，避免重复创建：

  def parentFolderPath = "${globalConfigurations.reuseLibraryCpmMaps}/${topicBodyItemTitle}"
  if (!resourceResolver.getResource(parentFolderPath)) {
      JcrUtil.createPath(parentFolderPath, JcrResourceConstants.NT_SLING_FOLDER, session, true)
  }
