在 kibana 控制台中不断收到此错误“找不到动态方法 [java.util.HashMap, add/1]”

Question

我是 elasticsearch 堆栈的新手...每当我尝试在 Kibana Dev Tool Console 中执行以下查询时，都会收到下面提到的错误

• 在 Kibana 控制台中执行查询

POST employees-details/_update_by_query
{
  "query": {
    "match": {
      "EmpName": "Arvind"
    }
  },
  "script": {
    "source": "ctx._source.Address.add(params.tag)",
    "lang": "painless",
    "params": {
      "tag":{
        "AddressID":144,
        "AddressNumber":458
      }
    }
  }
}

\/执行上述查询时不断出现此错误^^

"caused_by" : {
      "type" : "illegal_argument_exception",
      "reason" : "dynamic method [java.util.HashMap, add/1] not found"
    }

• 样本数据

[
      {
        "_index" : "employees-details",
        "_type" : "_doc",
        "_id" : "101",
        "_score" : 1.0,
        "_source" : {
          "EmpUserID" : 101,
          "Gender" : "Male",
          "EmpName" : "John",
          "Age" : 35
        }
      },
      {
        "_index" : "employees-details",
        "_type" : "_doc",
        "_id" : "106",
        "_score" : 1.0,
        "_source" : {
          "EmpUserID" : 106,
          "Address" : {
            "AddressNumber" : 201,
            "AddressID" : 200
          },
          "Gender" : "Male",
          "EmpName" : "Arvind",
          "Age" : 30
        }
      }
]

由于Address是一个散列，因此您不能使用该add()方法（适用于数组、列表等集合）。相反，您需要Address先转换为列表，然后调用add()：

POST employees-details/_update_by_query
{
  "query": {
    "match": {
      "EmpName": "Arvind"
    }
  },
  "script": {
    "source": "if (!(ctx._source.Address instanceof Collection)) {ctx._source.Address = [ctx._source.Address];} ctx._source.Address.add(params.tag)",
    "lang": "painless",
    "params": {
      "tag":{
        "AddressID":144,
        "AddressNumber":458
      }
    }
  }
}
