MVC Architecture in Spring Boot

In Spring Boot, the MVC pattern is implemented through various components and annotations provided by the Spring Framework.

Here’s a detailed of each component in MVC:

1. Model

The Model represents the application’s data and business logic. It is responsible for retrieving data from the database, processing it, and returning it to the Controller. In Spring Boot, the Model is typically represented by Java classes (also known as domain objects or entities) and service classes that contain business logic.

Components:

Entities: Represent the database tables.

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String email;

    // Getters and Setters
}

Repositories: Provide an abstraction layer to interact with the database.

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
    // Custom query methods can be defined here
}

Service Layer: Contains business logic and interacts with repositories.

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;

    public User getUserById(Long id) {…
