我是休眠新手并尝试运行应用程序，但在运行应用程序时遇到问题。我得到以下错误，
org.hibernate.MappingException: Unknown entity: DELETE com.on.transport.dto.updated.RoutePlaceMappingUpdated rpmu where rpmu.route.routeId=?
@Entity
@Table(name = "route_place_mapping")
public class RoutePlaceMappingUpdated {
@Id @GeneratedValue
@Column(name = "route_place_mapping_id")
private Long routePlaceMappingId;
@OneToOne(targetEntity=RouteUpdated.class)
@JoinColumn(name="route_id")
private RouteUpdated route;
@OneToOne(targetEntity=PlaceUpdated.class)
@JoinColumn(name="place_id")
private PlaceUpdated place;
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "arrival_time", nullable=false, length=19)
private Date arrivalTime;
@Column(name = "sequence_of_arrival")
private String sequenceArrivalAtPlace;
//getter - setter
}
@Entity
@Table(name = "route")
public class RouteUpdated {
@Id @GeneratedValue
@Column(name = "route_id")
private Long routeId;
@Column(name = "route_name")
private String routeName;
//getter-setter
}
@Entity
@Table(name = "place")
public class PlaceUpdated {
@Id @GeneratedValue
@Column(name = "place_id")
private Long placeId;
@Column(name = "place_name")
private String placeName;
//getter-setter
}
我正在调用以下函数，但出现错误。
@Override
public boolean deleteAllInBetweenPlaceOfRouteByRouteId(Long routeId){
String hql1 = "DELETE com.on.transport.dto.updated.RoutePlaceMappingUpdated rpmu where rpmu.route.routeId=?";
Object[] queryParam = {routeId};
getHibernateTemplate().delete(hql1, queryParam);
return true;
}
表结构
route
---------------
route_id int
route_name varchar
place
---------------
place_id int
place_name varchar
route_place_mapping
----------------------
route_place_mapping_id int
route_id int
place_id int
我在路线和地点属性的 RoutePlaceMappingUpdated 类中遗漏了一些东西，但我无法弄清楚。
