Well, there's a lot happening in the previous section! We should first have a look at the @Produces annotation. It is a CDI annotation that says to the server: "Hey! This method knows how to construct a User object."
As we didn't create a default constructor for the User class, the getUser method from our factory will be injected into our context as one.
The second annotation is our custom annotation @Profile that has our enumeration ProfileType as a parameter. It is the qualifier of our UserProfile objects.
Now, let's have a look at these declarations:
@Profile(ProfileType.ADMIN)public class ImplAdmin implements UserProfile{ ...}@Profile(ProfileType.OPERATOR)@Defaultpublic class ImplOperator implements UserProfile{ ...}
