Spring layers confusion

I am new to Spring and Hibernate, as of now no controller. I am actually facing problems defining the layers of my application. I have to create a movie site where I can search movies,theaters,search movies by theater names and theaters by movie name.I have below questions: 1. What could be the entities in my application, I have created MovieEntity and TheaterEntity so far, how to proceed with the mappings between two.

2.My project structure should be something like this: Entities, repositories and services. I am not sure where to fit my service layer, as all the methods I need to implement are defined in entities.
