Simple Package Structure for Spring Boot REST API — Video Tutorial

An opinionated package structure for a relatively simple REST API applications with Spring Boot

What are we building?

Example REST Endpoint — PingPong API

Assumptions:

• You have some models to store and fetch from storage.
• There is some business logic involved before saving an object.

Why even bother with a structure?

• Not over-complicated, but also not everything in one file.
• Easier to navigate.
• Paving the road for future extensions.

What’s inside?

• Only three layers.
• At a minimum, only one model conversion — Entity to DTO.

Advantages

• It is elementary to get started.
• Possibility to extend. For example, input validation can be done directly on the DTOs or by introducing Request and Response models at the top layer.
