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!
Unfortunately, there is no inheritance in annotations, so it's not possible.
Have a look at the answers to the similar question here:
No. The Java Language Specification says that type variables can only be constrained to extend / implement particular classes or interfaces. Since annotating a class does not cause the class to extend or implement a particular type, you can't constrain by annotation.
