休眠空间 jpa 查询不起作用

Question

我已经编写了空间查询来查找距某个位置最近的点。但是hibernate得到异常。 我的 Spring boot 1.5.7 应用程序

@Repository
@Transactional(readOnly = true)
public interface PlaceRepository extends JpaRepository<PlaceEntity, Long> {
    PlaceEntity findByCode(String code);
    PlaceEntity findByName(String name);
    @Query("select l from PlaceEntity l where within(l.location, :filter) = true")
    List<PlaceEntity> findLocationWithin(Geometry filter);
}

这里是我的实体类参数

@Data
@Entity(name = "Place")
public class PlaceEntity extends BaseEntity {

@Type(type = "org.hibernate.spatial.GeometryType")
@Column(name = "LOCATION",columnDefinition = "POINT")
    private Point location;
}

其他参数是

@Id
@GeneratedValue
@Column(name = "ID")
private long id;
@Column(name = "NAME")
private String name;
@Column(name = "CODE")
private String code;
@Column(name = "LONGITUDE")
private Double longitude;
@Column(name = "LATITUDE")
private Double latitude;

这是我的 build.gradle。

compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.hibernate:hibernate-core:4.3.0.Final')
compile("org.hibernate:hibernate-spatial:4.3")
compile("org.hibernate:hibernate-entitymanager:4.3.0.Final")
compile('mysql:mysql-connector-java')
compile('org.projectlombok:lombok:1.14.8')
compile('org.springframework.boot:spring-boot-starter-web')
compile('com.vividsolutions:jts:1.13')
testCompile('org.springframework.boot:spring-boot-starter-test')

配置

@EnableWebMvc
@Configuration
public class AppConfig {

}

但是当我部署服务器时出现异常。

我的配置有什么错误吗？

Answer 1

将来在 spring-data-jpa 存储库中使用变量，如 #{#entityName} 来保护自己免受此类错误的影响

@Query("select l from #{#entityName} l where within(l.location, :filter) = true")

Answer 2

您已将您的实体命名为 Place (@Entity(name = "Place"))，但您仍在 jpql 查询中使用 PlaceEntity。

这样试试；

select l from Place l where within(l.location, :filter) = true

或者在您的查询中继续使用PlaceEntity 并使用以下注释；

@Data
@Entity
@Table(name ="Place")
public class PlaceEntity extends BaseEntity {}
