С какими компонентами Spring'a приходилось работать

Работал с основными компонентами Spring Framework: - **Spring Core** (IoC, DI, Beans) - **Spring MVC** (Controllers, @RequestMapping, ModelAndView) - **Spring Boot** (Auto-configuration, Starter Packs) - **Spring Data JPA** (Repositories, @Entity, Hibernate integration) - **Spring Security** (Authentication, Authorization, JWT) - **Spring AOP** (@Aspect, @Before/@After advice) - **Spring REST** (@RestController, ResponseEntity) - **Spring Batch** (Job, Step, ItemReader/Writer) Пример контроллера: ```java @RestController @RequestMapping("/api/users") public class UserController { @Autowired private UserService userService; @GetMapping("/{id}") public ResponseEntity getUser(@PathVariable Long id) { return ResponseEntity.ok(userService.findById(id)); } } ```
