物业访问。吸气的逻辑

Question

ObjectID是我自己的ID级

在我映射的Entity-class中，我有ID的下一个getter

   @Id
   @Column(name = "aa_id")
   @SequenceGenerator(name = "PatientSequenceGenerator",
                      sequenceName = "patient_seq")
   @GeneratedValue(strategy = GenerationType.SEQUENCE,
                   generator = "PatientSequenceGenerator")
   public ObjectID getId()
   {
      return id;
   }  

生成器生成Long值，所以我得到了异常

this id generator generates long, integer, short or string  

那么，我是否可以添加到我的getter逻辑中，这将从long创建ObjectID，例如

//annotations
    public ObjectID getId()
           {  
//logic that that get Long from sequance
              return new ObjectID(gettedLong);
           }  

Answer 1

你不应该这样做。您的ID字段应为列出的类型之一，或@EmbeddedId或@IdClass
