What is your experience with the Spring framework?

Working with the Spring framework typically involves using its core modules:

• Spring Core — dependency management through the IoC (Inversion of Control) container.
• Spring MVC — building web applications using the Model-View-Controller pattern.
• Spring Boot — simplifying configuration and application startup, auto-configuration.
• Spring Data — working with databases via repositories.
• Spring Security — ensuring application security.

In practice, this means writing components with annotations like @Component, @Service, @Repository, using @Autowired for dependency injection, and configuring REST controllers with @RestController.

Example of a simple REST controller in Spring Boot:

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String sayHello() {
        return "Hello, Spring!";
    }
}
