Hibernate不在getter中提取@id注释

Question

在当前项目中，我得到了以下AnnotationException:

AnnotationException：没有为实体指定标识符：My.Package.EntityClass

@Entity
@Table(name = "MY_TABLE")
public class EntityClass extends BaseEntityClass {

  private long id;

  @Override
  public void setId(long id) {
    this.id = id;
  }

  @Override
  @Id
  @SequenceGenerator(name = "FOOBAR_GENERATOR", sequenceName = "SEQ_MY_TABLE", allocationSize = 1, initialValue = 1)
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "FOOBAR_GENERATOR")
  public long getId() {
    return this.id;
  }

}

@Entity
@Table(name = "MY_TABLE")
public class EntityClass extends BaseEntityClass {

  @Id
  @SequenceGenerator(name = "FOOBAR_GENERATOR", sequenceName = "SEQ_MY_TABLE", allocationSize = 1, initialValue = 1)
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "FOOBAR_GENERATOR")
  private long id;

  @Override
  public void setId(long id) {
    this.id = id;
  }

  @Override
  public long getId() {
    return this.id;
  }

}

或者这种行为在Hibernate版本之间发生了变化？

只有到那时，您才需要在所有getter上一致地使用@id。确保没有用@id而不是getter注释字段。混合和匹配会使它停止正确工作。
