I don't have CGLIB in the dependency hierarchy. I'm using only interfaces for DI and I've tried to disable @EnableGlobalMethodSecurity(securedEnabled = true) and everything related to it, but still no change.(I've read that MethodSecurity and @Secured annotations in the Controller Classes can caused this WARNing, but it seems that I get them from another place. How to know from where I receive these warnings ?

Answer 1

The problem was with some @Transactional annotations on a Class level. After I put them on the interfaces (Repositories - I'm using spring data) Everything is OK :)
