Do I really need a service layer?

Question

My web application is written using Spring MVC + Hibernate.

• My model is \"Customer\" entity POJO.
• I have got a DAO object \"CustomerDAO\", its method

Answer 1

Right now, your service layer is trivial because your service is a trivial wrapping around database accesses. Is that all the app is? If not, when you start building the non-trivial parts, your service layer will expand.
