Glassfish 说不完整的 JoinColumns

Question

我使用了组合键，但我改变了主意并在 NetBeans 的 Web 应用程序中删除了这种键。但是 Glassfish 说：模块尚未部署，因为 JoinColumns 内容无效。

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.

我已经从数据库中删除了所有表，重新启动了容器，对项目调用了"Clean and Build"命令（它成功了）。但是 EJB 部署失败。容器忘记过去怎么办？

实体源代码：

@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

好的。 UserRole table 中有错误。我忘记删除 userWR 字段上的第二个 @Id 注释。在我删除它并重建它再次部署的应用程序之后。
