Spring Data Elasticsearch GeoPoint Field in Index

Recently I was working on a Project which involved Spring Data Elasticsearch and needed to use geo_point type field in the Elasticsearch index for speedier location based searches. Spring Data Elasticsearch provides a data type by the name GeoPoint to achieve this and an annotation named @GeoPointField to mark such fields.

@Document(indexName = "properties", replicas = 0, refreshInterval = "-1")
public class Property implements Serializable {

    ...
    @GeoPointField
    private GeoPoint location;
    ...

 

But sadly for me creating a repository out for the above @Document and saving objects was keep on converting the GeoPoint field to a plain map of latitude and longitude but not as a geo_point field. 

    "location": {
      "properties": {
        "latitude": {
          "type": "string"
         },
        "longitude": {
          "type": "string"
        }
      }
    } 

This results in following error while querying using Geo Distance Query. 

QueryParsingException failed to find geo_point field

After some research I finally found out that in such cases we would need to manually create the index before calling Repository.save.

In a service or any other initializer class you need to do the following;

@Autowired
private ElasticsearchRestTemplate elasticsearchRestTemplate;

@PostConstruct
public void init() {
    IndexOperations indexOperations = elasticsearchRestTemplate.indexOps(Property.class);
    indexOperations.putMapping(indexOperations.createMapping());
    indexOperations.refresh();
}

 This fixes the issue and creates the location field with type geo_point as expected.
