我正在尝试找到所有在我提供的范围内的实体。我的意思是，如果我给定一个特定半径的圆，它将必须显示所有位置坐标位于给定圆内的实体。
我使用hibernate-spatial来实现这一点。但在JPA Repository接口中遇到了上述错误。
这是pom.xml文件：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-spatial</artifactId>
<version>5.2.12.Final</version>

<version>${project.version}</version>

</dependency>
JPA仓库，
public interface ResourceRepository extends ExtendedJpaRepository<Resource, String> {
@Query(value = "select resource from Resource resource where within(resource.address.location, :circle) = true")
List<Resource> test(@Param("circle") Geometry circle);
}
Resource.java,
@Entity
@NoArgsConstructor
public class Resource extends UUIDEntity2 implements IsResource {
@Type(type = "org.hibernate.spatial.GeometryType")
@OneToOne
private Address address;
/*getters setters*/
}
Address.java ,
@Entity
public class Address extends UUIDEntity2 implements HasEmailAddress, HasLocation {
@Embedded
@Column(columnDefinition = "point")
private Location location;
/*getters setters*/
}
location.java,
@Embeddable
@Value(staticConstructor = "of")
@RequiredArgsConstructor(staticName = "of")
public class Location implements Serializable {
@Column(nullable = true)
private Double lat;
@Column(nullable = true)
private Double lon;
}
测试，
@Inject
private ResourceRepository resourceRepository;
public Geometry createCircle(double x, double y, double radius) {
GeometricShapeFactory shapeFactory = new GeometricShapeFactory();
shapeFactory.setNumPoints(32);
shapeFactory.setCentre(new Coordinate(x, y));
shapeFactory.setSize(radius * 2);
return shapeFactory.createCircle();
}
@Test
public void geometry(){
Geometry m = createCircle(0.0, 0.0, 5);
List<Resource> resources = resourceRepository.test(m);
}
application.properties,
hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56SpatialDialect
注意：这里未显示实体的所有属性。 我所遵循的参考资料为：Hibernate-Spatial。
