Builder Studio Options to introduce Layers in Spring Java API Design Pattern to meet your project requirements.

  • Service Layer - For Business Logic
  • DTO Pattern - To Bring all required data in one go from multiple entities.

Layers in this Pattern:

  • Presentation Layer
    • Controller
  • Business Layer: Business Logic, Validations
    • Service Layer
    • DTO (Data Transfer Object)
    • Mapper (Convert Entity to DTO)
  • Data Access | Persistence Layer
    • Repository
    • Entity


  • Convert the domain objects to the DTO in the service layer as part of Business Logic.
  • Reduce the accessability of domain objects only to service layer.
  • Reduce the business logic inside controllers, use them for/as Presentation Layer.
