Explanation

Microservices divide an application into small independent services.

Code:

Student Service
Course Service
Payment Service

Explanation

Each microservice has its own Spring Boot project.

Code:

@SpringBootApplication
public class StudentServiceApplication{}

Explanation

Microservices communicate using REST APIs.

Code:

GET http://localhost:8082/courses

Explanation

Use RestTemplate or WebClient to call another microservice.

Code:

webClient.get()
.uri("http://course-service/courses")

Explanation

Each service owns its own database to ensure loose coupling.

Code:

StudentDB
CourseDB
PaymentDB
