org.hibernate.AnnotationException: No identifier specified for entity

I have a groovy entity ClientInvoiceAttachmentExt which extends java entity ClientInvoiceAttachment. The ClientInvoiceAttachment has @Id annotation but still am seeing the "No identifier specified for entity" error

Here is my stack trace

Your problem scenario is of Inheritance Mapping. The Id field is there in your super class but what about your child class, how they will be related to their parent.

There are different strategy to map an Inheritance hierarchy.

  1. Using Discriminator value (Single Table)
  2. Table per concrete class
  3. Table per Child class (if parent is an abstract)

I think you are missing annotations related to above.

In Discriminator based approach.. You need to annotate your ParentClass as follows:

@Inheritance(strategy=InheritanceType.SINGLE_TABLE)  
@DiscriminatorColumn(name="type",discriminatorType=DiscriminatorType.STRING)  
@DiscriminatorValue(value="ParentClass")  

And in you child class:

@DiscriminatorValue("childClasss")

Please refer some tutorial on Inheritance Mapping like this one or you can google it.

There is a new annotation @MappedSuperclass that you add to the base class and it only affects the OOP without the need to change the DB. That is what I was looking for. You can read more about it in this post

I got the same error while working with JPA & I have added the @Id annotation,

While working with JPA, kindly make sure that this @Id annotation should be from package javax.persistence.Id & not from org.springframework.data.annotation.Id.

Hope it can save your precious time.
