遇到的问题：

错误信息显示，日期字段updateTime的格式是"2025-03-13T07:57:53.000Z"，但Elasticsearch的映射期望的是"yyyy-MM-dd HH:mm:ss"格式，导致解析失败 

简单的理解就是就是时间格式不准确：
于是我更新了一下我的时间格式在es里面：

解决方案：

可能会出现，索引已经存在的错误那样的话，删掉即可。

 # 2. 创建新索引，并定义映射
PUT /wk_single_make
{
  "mappings": {
    "_doc": {
      "properties": {
        "updateTime": {
          "type": "date",
          "format": "strict_date_optional_time||yyyy-MM-dd HH:mm:ss"
        },
        "createTime": {
          "type": "date",
          "format": "strict_date_optional_time||yyyy-MM-dd HH:mm:ss"
        }
      }
    }
  }
}

 这样就好了。

同时我也更新了一下实体类让其格式一致：
