Question

我使用了复合键，但我改变了主意，在NetBeans中的Web应用程序中删除了这种键。但是Glassfish说：由于JoinColumns内容无效，该模块尚未部署。

Exception Description: The @JoinColumns on the annotated element [field client] from the entity class [class x.ClientOrder] is incomplete. When the source entity class uses a composite primary key, a @JoinColumn must be specified for each join column using the @JoinColumns. Both the name and the referencedColumnName elements must be specified in each such @JoinColumn.

我已从数据库中删除了所有表，重新启动了容器，称为＆＃34;清理和构建＆＃34;对项目的命令（成功）。但是EJB部署失败了。我应该怎样做容器忘记过去？

实体的源代码：

@Entity
@Getter
@Setter
@Inheritance( strategy = InheritanceType.JOINED )
@DiscriminatorColumn( name = "roleType", discriminatorType = DiscriminatorType.STRING, length = 10 )
@NamedQuery( name=UserRole.QUERYNAME_GET_ROLE_BY_USERID_AND_TYPE, query = "SELECT ur FROM UserRole ur WHERE ur.userWR.id = :userID AND ur.roleType = :roleType" )
abstract public class UserRole implements Serializable
{
  private static final long serialVersionUID = 1L;
  public static final String QUERYNAME_GET_ROLE_BY_USERID_AND_TYPE = "userRole_getRoleByUserIDAndType";

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

  @Column
  private String roleType;

  @Id
  @ManyToOne
  @JoinColumn( name="user_id", referencedColumnName = "id" )
  private UserWithRoles userWR;

}


@Entity
@Data
@NamedQuery( name = Client.QUERYNAME_GET_ALL_CLIENTS, query="SELECT c FROM Client c" )
public abstract class Client extends UserRole
{
  public static final String QUERYNAME_GET_ALL_CLIENTS = "client_GetAllClients";

}


@Entity
@Data
@NamedQuery( name=ClientOrder.QUERYNAME_GET_CLIENT_ORDERS, query = "SELECT co FROM ClientOrder co WHERE co.client = :userID" )
public class ClientOrder implements Serializable
{
  private static final long serialVersionUID = 1L;
  public static final String QUERYNAME_GET_CLIENT_ORDERS = "clientOrders_getClientOrders";

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

  private String name;

  @ManyToOne
  @JoinColumn( name = "client_id", referencedColumnName = "id" )
  private Client client;

  @OneToMany( mappedBy = "clientOrder" )
  private List<ClientOrderItem> orderItems;

}

Answer 1

行。 UserRole表中存在错误。我忘了删除userWR字段上的第二个@Id注释。在我删除它并重建应用程序后，它再次部署。

Glassfish说不完整的JoinColumns
