@sdolman great question, thanks! It has been a long time since I used this and I don't have the specific project code anymore. @Component might work, but I'm not sure since this is used as a trick by calling it in the @DependsOn annotation in a DatabaseConfig class. I'm definitely curious though. Did it work for you?

How can i configured this class from spring xml based config?Any idea

@Prithal, sorry but I haven't done spring xml config in a long time. I'm not sure exactly, but somehow you would need to run the register() method in a PostConstruct, and have the config depend on hibernatePersistenceProviderResolver
