Question

我在使用FOSElastica捆绑包配置时遇到了麻烦。我使用了JMS序列化程序，并且尝试添加对象，这些对象的字段实际上包含一个json数组。但是，当我尝试填充其中的一些错误时，会出现以下错误：

  Error in one or more bulk request actions:                                                                                                 

  index: /table_content/table_content/10 caused mapper [corrected_value_float.args.argument1] cannot be changed from type [long] to [float]  
  index: /table_content/table_content/11 caused mapper [difference_value_float.entry] cannot be changed from type [float] to [long]

目前，我很难理解他如何推断json数组中的参数类型。需要明确的是，我认为JMS像其他对象一样将对象序列化，并将{“ field”：“ value”}关联为json，这里的数据库中的“ value”是实际的json数组，因此elastica对其进行了索引并确定了其种类“猜测”数组值的类型。

/ table_content / table_content / 10的问题json数组（我想他不喜欢“ argument1”末尾的100）：

}
}

/ table_content / table_content / 11的问题json数组：

{"args": {
"entry":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
}
}

对于第二个有问题的数组，我什至不理解为什么当它仅由0组成时，为什么他认为其中一个数字是浮点数。

即使我为其余对象使用了序列化器，我怎么能告诉他要给json数组值指定什么类型呢？它会在弹性束中的哪个位置“猜测”这些阵列中的什么类型？

Answer 1

因此，一段时间后，我找到了解决问题的方法：Dynamic templates和Index templates

我实际上遇到了ElasticSearch无法识别某些类型的字段（例如date或geo_point）的麻烦，因此我借助模板将它们强制用于特定命名的字段。

如果要获取我在FOSElastica（doc is here）中的配置示例：

fos_elastica:
    serializer: 
        serializer: jms_serializer
    clients:
        default: 
            host: localhost 
            port: 9200
    index_templates: # https://www.elastic.co/guide/en/elasticsearch/reference/6.8/indices-templates.html
        base_template: # this is a custom name for the index template
            client: default
            template: "*" # this is where you define which indices will use this template
            types:
                _doc: # this is where you define which types will use this (_doc stands for every type/documents)
                    dynamic_templates: # https://www.elastic.co/guide/en/elasticsearch/reference/6.8/dynamic-templates.html
                        dynamic_date_template: # this is a custom name for the dynamic field template
                            match_pattern: regex
                            match: created|updated|tpq_date|taq_date
                            mapping:
                                type: date
                        dynamic_location_template:
                            match: location
                            mapping:
                                type: geo_point

Answer 2

Elasticsearch将根据它索引的第一个文档（如果您不提供）创建一个映射。尝试检查索引的_mapping。您可以自己指定一个映射，以避免这种情况。

批量请求中出现错误：[arg]无法从[long]类型更改为[float]
