Core 3.2.CR2, Annotations 3.2.0 CR1, EntityManager 3.2.0 CR1


Hibernate provides a very useful @Formula annotation to let you create a calculated property. You can annotate a property using @Formula instead of @Column. However, you can’t use @Formula where @Column is used in other places. For example, @AttributeOverride’s column attribute accepts @Column. But you can’t assign a @Formula to the column attribute. If @Formula extends @Column, then this problem can be solved.

In addition, we can use <formula> tag inside <many-to-one> tag in hibernate’s mapping file, *.hbm.xml. However, we lose this feature when we move to EJB3.0 annotations even with Hibernate’s @Formula extension. If there is a way to bring this feature back, that will be great.

JDK 5 annotations have no notion of inheritance
