Event Controller

In this lesson, we'll implement the REST API endpoint for creating events.

Create the Event Controller

The event controller is responsible for handling HTTP requests related to events. Let's create a new controller class with Spring's @RestController annotation:

@RestController
@RequestMapping("/api/v1/events")
@RequiredArgsConstructor
public class EventController {
    private final EventMapper eventMapper;
    private final EventService eventService;

    @PostMapping
    public ResponseEntity<CreateEventResponseDto> createEvent(
            @AuthenticationPrincipal Jwt jwt,
            @Valid @RequestBody CreateEventRequestDto createEventRequestDto) {
        // Convert DTO to domain object
        CreateEventRequest createEventRequest = eventMapper.fromDto(createEventRequestDto);

        // Extract user ID from JWT
        UUID userId = UUID.fromString(jwt.getSubject());

        // Create the event
        Event createdEvent = eventService.createEvent(userId, createEventRequest);

        // Convert response to DTO
        CreateEventResponseDto createEventResponseDto = eventMapper.toDto(createdEvent);

        return new ResponseEntity<>(createEventResponseDto, HttpStatus.CREATED);
    }
}
