Intro
Final recap: Let’s review the REST API mini project from start to finish.
Review design
- Defined endpoints like
GET /tasksandPOST /tasks - Modeled Task entity with id, title, done
- Planned flow: Controller → Service → Repository
Review implementation
We implemented entity, repository, service, and controller classes. Each had clear responsibility.
Code: summary demo
A simple demo prints the project layers, endpoints, and extensions.
public class Main {
public static void main(String[] args) {
System.out.println("Layers: Controller → Service → Repository");
System.out.println("Endpoints: GET, POST, PUT, DELETE /tasks");
System.out.println("Extensions: search, pagination, validation");
}
}
Review testing
We wrote JUnit tests and simulated API checks with MockMvc. Tests verified endpoints worked as expected.
Review extensions
- Added search endpoint
?done=true - Supported pagination for lists
- Validated empty task titles
Layers check
Quick check: Which layers typically make up a Spring Boot REST API?
Final recap
Recap: Reviewed design, implementation, testing, and extensions. You now have a full view of building a REST API project.
