Have you had experience working with the Spring framework in your projects?

Yes, I have experience working with the Spring framework in several projects. I used Spring Boot for quickly creating REST APIs, configuring components through annotations such as @Controller, @Service, @Repository. I also worked with Spring Data JPA for database interactions, which greatly simplified CRUD operations.

Example of a simple controller in Spring Boot:

@RestController
@RequestMapping("/users")
public class UserController {

    private final UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @GetMapping("/{id}")
    public ResponseEntity<User> getUser(@PathVariable Long id) {
        return ResponseEntity.of(userService.findById(id));
    }
}

Spring allows for the rapid development of scalable and maintainable applications thanks to its modularity and a large number of ready-made solutions.
