PRA#02-SpringBoot: Create User API Rest

✅ Completed Tasks

• Create User entity
• Implement UserController (REST API controller)
• Develop UserRepository
• Configure application properties with a local H2 database
• Implement UserService
• Test all endpoints with Postman

---

📌 Implementation Details

1. Create User Entity

• I created both entities: User and Word. Initially, I attempted to use Lombok's @Data annotation, but it didn't work as expected, so I manually added all getters and setters.

2. Create UserController

• I created controllers for both entities.
• WordController includes all standard CRUD methods.
• UserController implements CRUD methods along with additional custom endpoints.

3. Implement UserRepository

• Both UserRepository and WordRepository extend JPA.
• UserRepository includes custom queries for additional functionality.

4. Configure H2 Database

• My initial plan was to test with PostgreSQL, but due to time constraints, I opted for H2.
• I configured H2 with the create-drop strategy since I didn't need persistent data.

5. Develop UserService

• I first created UserService as an interface and then implemented it in UserServiceImpl.
• I followed the same approach for WordService and WordServiceImpl.

6. Postman Endpoint Testing

• I successfully tested all endpoints using Postman.

🚀 Optional Enhancements

• Implement data seeding using Faker
• Advanced testing strategies
• Implement new custom queries
• Additional improvements

Custom Queries

• I added custom queries in UserRepository, integrated them into UserService and UserServiceImpl, and exposed them via new endpoints in UserController.

Additional Improvements

• I added all necessary annotations.
• I also included an extra validation annotation for password formatting using @Pattern.

Below I add some screenshots.
