Java Generics and Annotations: Type-Safe

Question

I know I can do something like:

public class AbstractDao<T extends Bean> {

}

In this case, the Bean is a class or interface.

I was wondering if there is a way to do this using annotations, for example:

public class AbstractDao<T extends javax.persistence.Entity> {

}

Is this possible?

Thanks in advance!

Answer 1

Unfortunately, annotations do not have inheritance, so this is not possible.
