Elasticseach:“类型”：“映射程序\u解析\u异常”

Question

我是elasticseach的新手，正在尝试为自己的学习前景执行小任务。我指的是https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html链接以创建动态模板；然而，当运行下面提到的查询时，我得到了“type”：“mapper_parsing_exception”，“reason”：“根映射定义有不支持的参数：error”。

有人能帮我解决这个错误吗？看起来我没有在正确的位置定义模板名称。

PUT e_review_dynamictemplate
{
  "mappings": {
    "date_detection": true,
    "dynamic_date_formats": ["dd/MM/yyyy"], 
    "numeric_detection": true, 
    "My_dynamic_templates": [
      {
      "e_full_name": {
          "path_match":   "*_Name",
          "mapping": {
            "type":       "text",
            "copy_to":    "e_full_name",
            "norms": false
          }
        },
      "integers": {
          "match_mapping_type": "long",
          "mapping": {
            "type": "integer",
            "index": false
          }
        },
      "strings": {
         "match_mapping_type": "string",
         "match":   "Achievements:*",
         "unmatch": "Improvements:*",
          "mapping": {
            "type": "long"
          }
        }
      }
      ]
  }
}

提前谢谢！尼维迪塔

您刚刚错过了映射对象中的dynamic_templates属性。您只需将My_dynamic_templates替换为dynamic_templates。

自定义名称用于dynamic_templates数组中的模板定义。

以下是更正后的代码片段：

PUT e_review_dynamictemplate
{
  "mappings": {
    "date_detection": true,
    "dynamic_date_formats": [
      "dd/MM/yyyy"
    ],
    "numeric_detection": true,
    "dynamic_templates": [
      {
        "e_full_name": {
          "path_match": "*_Name",
          "mapping": {
            "type": "text",
            "copy_to": "e_full_name",
            "norms": false
          }
        }
      },
      {
        "integers": {
          "match_mapping_type": "long",
          "mapping": {
            "type": "integer",
            "index": false
          }
        }
      },
      {
        "strings": {
          "match_mapping_type": "string",
          "match": "Achievements:*",
          "unmatch": "Improvements:*",
          "mapping": {
            "type": "long"
          }
        }
      }
    ]
  }
}
