tags: ["附件解析", "ID冲突", "文档管理"]
summary: "版本： 6.8-6.8
 简而言之，当Elasticsearch中已存在相同ID的附件时，就会出现此错误。Elasticsearch使用唯一ID来识别和管理文档。如果您尝试使用已存在的ID创建新文档，系统将抛出此错误。要解决此问题，您可以重命名新文档的ID或删除具有相同ID的现有文档。此外，您也可以使用"更新"API来更新现有文档，而不是创建新文档。
日志上下文 #  日志"Attachment with id [{}] has already been created; must be renamed"的类名是 EmailAttachmentsParser.java。我们从Elasticsearch源代码中提取了以下内容，供那些寻求深入上下文的用户参考：
if (emailAttachmentParser == null) { throw new ElasticsearchParseException("Cannot parse attachment of type [{}]"; currentAttachmentType); } EmailAttachmentParser.EmailAttachment emailAttachment = emailAttachmentParser.parse(currentFieldName; parser); if (attachments.containsKey(emailAttachment.id())) { throw new ElasticsearchParseException("Attachment with id [{}] has already been created; must be renamed"; emailAttachment.id()); } attachments.put(emailAttachment.id(); emailAttachment); // one further to skip the end_object from the attachment parser."

日志上下文
-----------

日志"Attachment with id [{}] has already been created; must be renamed"的类名是[EmailAttachmentsParser.java](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/)。我们从Elasticsearch源代码中提取了以下内容，供那些寻求深入上下文的用户参考：

```java
if (emailAttachmentParser == null) {
    throw new ElasticsearchParseException("Cannot parse attachment of type [{}]"; currentAttachmentType);
}

EmailAttachmentParser.EmailAttachment emailAttachment = emailAttachmentParser.parse(currentFieldName; parser);
if (attachments.containsKey(emailAttachment.id())) {
    throw new ElasticsearchParseException("Attachment with id [{}] has already been created; must be renamed";
    emailAttachment.id());
}
attachments.put(emailAttachment.id(); emailAttachment);
// one further to skip the end_object from the attachment
parser.nextToken();
```
