How does this work with the Spring decoration? In the @Mapper we are doing some special stuff in case someone uses @AnnotateWith with @Component.

For spring, I removed duplicates of @Component and @Primary (just like @component in mapper).

For jsr330/jarkata, since they do not support combined annotations like spring, combined annotations added by users (such as contain @Named) don't work; repeated additions of @Named and @Singleton will also cause compilation errors, so I think they don't need to be processed, just add corresponding tests to ensure that the annotations added by @AnnotateWith can take effect.

Do you think there are other scenarios that need to be handled? @filiphr
