弹性弹性搜索自定义字段名称 [英] Spring Elastic Search Custom Field names

问题描述

我有新的弹性搜索，我正在尝试使用Spring-data-elasticsearch实现它。我有一个名称如交通，我们的弹性搜索文件中的Telephone_Number。

当我尝试将我的@Domain对象字段映射到这些对象字段时，我没有得到任何数据，因为我不能成功地映射这些字段。

尝试使用@Field，令人失望，因为它没有name属性来映射自定义字段名称。 >

尝试了GETTER函数的不同变体，没有一个似乎映射到这些字段。

我开始想知道是否有一些我在这里错过的东西
域对象字段的外观如何映射到称为运输的文件？

任何帮助赞赏

解决方案

您可以使用自定义名称。 Spring Data ES使用Jackson。因此，您可以使用 @JsonProperty（your_custom_name）在ES映射

中启用自定义名称：

  @Document（indexName =your_index_name，type =your_type_name）
 public class YourEntity {
 .... 
 @JsonProperty（my_transportation）
 @Field（type = FieldType.String，searchAnalyzer =standard，indexAnalyzer =standard，store = true）//例如
 private String myTransportation; 
 .... 
} 
  

注意：我很抱歉，我的英文不好..：D

I am new to Elastic Search and I am trying to implement it using Spring-data-elasticsearch.

I have fields with names such as "Transportation", "Telephone_Number" in our elastic search documents.

When I try to map my @Domain object fields with those, I don't get any data for those as I couldn't successfully map those fields.

Tried to use @Field, was disappointed as it didn't have 'name' property in it to map with custom field name.

Tried different variations of a GETTER function, none of those seem to be mapping to those fields.

I started wondering if there's something I'm missing here. How does a domain object field look like which should map to a filed called something like "Transportation" ?

Any help appreciated

解决方案

You can use custom name. Spring Data ES use Jackson. So, you can use @JsonProperty("your_custom_name") to enable custom name in ES Mapping

for example:

@Document(indexName = "your_index_name", type = "your_type_name")
public class YourEntity {
   ....
   @JsonProperty("my_transportation")
   @Field(type = FieldType.String, searchAnalyzer = "standard", indexAnalyzer = "standard", store = true) // just for example
   private String myTransportation;
   ....
}

Note: I'm sorry anyway, my english is bad.. :D
