Elasticseach："type“：mapper_parsing_exception

Question

我对弹性训练很陌生，为了我自己的学习前景，我试图完成一些小任务。我参考https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html链接来创建一个动态模板；但是，在运行下面提到的查询时，我得到了"type“："mapper_parsing_exception"，”理由“：”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？看来我还没有在合适的地方定义我的模板名。

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"
          }
        }
      }
      ]
  }
}

提前感谢！尼维地塔

您刚刚错过了dynamic_templates对象中的mappings属性。您只需用My_dynamic_templates替换dynamic_templates即可。

自定义名称在dynamic_templates数组中的模板定义中使用。

以下是更正后的片段：

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"
          }
        }
      }
    ]
  }
}
