Java Generics and Annotations: Type-Safe

Question

I know that I can do something like:

public class AbstractDao<T extends Bean> {

}

In this case, Bean is an class or interface.

I was wondering if is there a way to do this with annotations, like:

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

}

Is something like this possible?

Thanks in advance!

Answer 1

Unfortunately, there is no inheritance in annotations, so it's not possible.
