What components or modules of Spring have you used in your projects?

In Spring projects, I used the following main components and modules:

• Spring Core — for dependency injection and bean lifecycle management.
• Spring MVC — for creating RESTful web services and handling HTTP requests.
• Spring Data JPA — to simplify working with databases through repositories and ORM.
• Spring Security — for implementing authentication and authorization.
• Spring Boot — for rapid project startup with minimal configuration.

Example of using Spring Boot with a controller:

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