Spring Data Elasticsearch无法找到geo_point字段

Question

我有一个用于使用Elasticsearch Geopoint的Spring Boot应用程序。当我保存弹性索引并创建geoDistanceQuery时，我得到了QueryShardException [未能找到geo_point字段[客户]]异常。

我的文档；

import lombok.Getter;
import lombok.Setter;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.GeoPointField;
import org.springframework.data.elasticsearch.core.geo.GeoPoint;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Getter
@Setter
@Document(indexName = "customer", replicas = 0, refreshInterval = "-1")
public class Customer {

    @GeneratedValue(strategy= GenerationType.AUTO)
    @Id
    private String id;

    private Integer cifNo;

    private String userId;

    private String name;

    @GeoPointField
    private GeoPoint geoPoint;

}

存储库；

@Repository
public interface CustomerRepository extends ElasticsearchRepository<Customer, String> { }

保存和获取方法；

import com.system.management.domain.entity.Customer;
import com.system.management.repository.CustomerRepository;
import org.elasticsearch.common.unit.DistanceUnit;
import org.elasticsearch.index.query.GeoDistanceQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.query.NativeSearchQueryBuilder;
import org.springframework.data.elasticsearch.core.query.SearchQuery;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
public class LocationFinder {

    @Autowired
    public ElasticsearchOperations elasticsearchTemplate;

    @Autowired
    public CustomerRepository customerRepository;

    public void saveNewLocation(Customer customer) {
        customerRepository.save(customer);
    }

    public List<Customer> getLocationMembers(){
        GeoDistanceQueryBuilder geoDistanceQueryBuilder = QueryBuilders
                .geoDistanceQuery("customer")
                .point(29.976, 31.131)
                .distance(10, DistanceUnit.KILOMETERS);

        SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withFilter(geoDistanceQueryBuilder)
                .build();
        return elasticsearchTemplate.queryForList(searchQuery,Customer.class);
    }
}

测试方法；

@Test
public void testLocation() {
    Customer customer = new Customer();
    customer.setName("base");
    customer.setCifNo(1242343);
    customer.setGeoPoint(new GeoPoint(29.876, 31.231));

    locationFinder.saveNewLocation(customer);
    List<Customer> customerList = locationFinder.getLocationMembers();
    Assert.assertNotEquals(0,customerList.size());
}

异常跟踪；

我的弹性版本； 7.5.1Spring数据弹性版本；

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>3.2.3.RELEASE</version>
</dependency>

当我获得http://localhost:9200/customer/_mapping网址时；

{"customer":{"mappings":{"properties":{"cifNo":{"type":"long"},"geoPoint":{"type":"geo_point"},"name":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":256}}}}}}}

我该如何解决此问题？

Answer 1

您的点坐标，纬度和经度不在km中，而您在其中以km测试距离。给定点之间的距离不是您所期望的〜0.142，而是14.71 km。您指定的距离为10公里。这就是为什么搜索正确地找不到该点的原因。

详细信息：

[（29.976，31.131）与（29.876，31.131）之间的东西距离是11.12 km（不是0.1 km）。

[29.876，31.131）和（29.876，31.231）之间的南北距离是9.64 km（不是0.1 km）。

（（29.976，31.131）与（29.876，31.231）之间的距离是14.71公里。
