英文:
Custom GeoPoint object in Spring Data Elasticsearch
问题
使用 Spring Boot 2.3.4。
是否有一种方法可以使用自定义的 GeoPoint 对象，而不是 org.springframework.data.elasticsearch.core.geo.GeoPoint？
如果可以，如何覆盖映射？putMapping 已被弃用。
@Document(indexName="myIndex")
public class MyDocument{
@GeoPointField
private MyPositionDocument position;
// 目前这只适用于
// private GeoPoint position;
}
英文:
Using spring boot 2.3.4.
Is there a way to use a custom GeoPoint object instead of org.springframework.data.elasticsearch.core.geo.GeoPoint ?
If so, how could the mapping be overridden ? putMapping is deprecated.
@Document(indexName="myIndex")
public class MyDocument{
@GeoPointField
private MyPositionDocument position;
// currently this only works with
// private GeoPoint position;

你已经拥有了第一部分，使用 @GeoPointField 对属性进行注解。这确保了将写入正确的索引映射，以便 position 的类型为 geo_point。
接下来，您需要创建自定义转换器，将 MyPositionDocument 转换为Elasticsearch支持的类型（https://www.elastic.co/guide/en/elasticsearch/reference/current/geo-point.html#geo-point），以及反向的一个转换器。
至于注册自定义转换器，请参阅https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.mapping.meta-model.conversions。
英文:
You already have the first part, annotating the property with @GeoPointField. This ensures that the correct index mappings will be written so that the type of position will be geo_point.
The next thing is that you will need to create custom converters to convert from a MyPositionDocument to a type that is supported by Elasticsearch (https://www.elastic.co/guide/en/elasticsearch/reference/current/geo-point.html#geo-point) and one converter for the other direction.
As for registering custom converters, see https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.mapping.meta-model.conversions
