CRUD backend in SpringBoot

Uses PostgreSQL as the database with Hibernate and Spring Data JPA.

This is a Maven project.

PostgreSQL should be installed and running.

1. Create the database:

   CREATE DATABASE student;

2. (Optional) Configure database credentials: If your PostgreSQL requires authentication, edit src/main/resources/application.properties:

   spring.datasource.username=your_username
   spring.datasource.password=your_password

3. Start the application:

   ./mvnw spring-boot:run

   The application will run on http://localhost:8080. Or you can specify a different port:

   ./mvnw spring-boot:run -Dspring-boot.run.arguments="--server.port=8081"

• GET /api/v1/student - Get all students
• POST /api/v1/student - Add new student (with JSON body containing name, email, and dob)
• PUT /api/v1/student/{id} - Update student (with query params for name and email)
• DELETE /api/v1/student/{id} - Delete student

Can be tested using Postman or whatever you want.

Going into src/main/java/com/example/demo the main method is in DemoApplication.java. The rest of the code is in the student folder.

• Student.java: POJO defining a student
• StudentConfig.java: Just creates 2 initial students and saves them to the database
• StudentController.java: RestController that exposes REST API endpoints for CRUD operations (GET all students, POST new student, PUT update student, DELETE student)
• StudentRepository.java: JPA Repository interface. Provides database operations. Used by the service layer
• StudentService.java: Service layer containing business logic for managing students. Used by the controller
