Question

ObjectID is my own ID-class

In my mapped Entity-class I have next getter for ID

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

generator generate Long value, so I got exception

this id generator generates long, integer, short or string  

So, do I can add to my getter logic, that will create ObjectID from long, for example

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

Answer 1

You shouldn’t do that. Your ID field should be of one of the listed types or an @EmbeddedId or an @IdClass
