Sample generated file

One representative file from a generated Spring app. Your generated output will include many more files like this one, customized to the entities and flows in your blueprint.

src/main/java/com/app/items/ItemsController.java

@RestController
@RequestMapping("/items")
@RequiredArgsConstructor
public class ItemsController {
    private final ItemsService service;

    @PostMapping
    public ResponseEntity<Item> create(
            @RequestBody @Valid CreateItemDto dto,
            @AuthenticationPrincipal AppUser user) {
        Item item = service.create(dto, user);
        return ResponseEntity
            .created(URI.create("/items/" + item.getId()))
            .body(item);
    }
