SpringBoot Applcation failed to start

Hi All,

I am newbie in the Spring Boot world, I am facing a problem while starting spring boot application below i am sharing some inputs:

@Repository
public interface UserRepository extends ReactiveCrudRepository<User, Long> {}

public interface UserManagementService {
    Mono<ResponseEntity<ApiResponse<String>>> addUser(AddUserRequest request);
}

@Service
@AllArgsConstructor
public class UserServiceImpl implements UserManagementService {
    private UserRepository userRepository;
    private ModelMapper mapper;

//  @Autowired
//  public UserServiceImpl(UserRepository userRepository, ModelMapper mapper) {
//      this.userRepository = userRepository;
//      this.mapper = mapper;
//  }

    @Override
    public Mono<ResponseEntity<ApiResponse<String>>> addUser(AddUserRequest request) {

        String username = request.getUName();
        return userRepository.findByUsername(username).flatMap(existingUser -> {
            ApiResponse<String> response = new ApiResponse<>(MessagesUtils.FAIL,
                    HttpStatus.CONFLICT.value(),
                    MessagesUtils.DUPLICATE_USER);
            return Mono.just(ResponseEntity.status(HttpStatus.OK).body(response));
        }).switchIfEmpty(saveNewUser(request));

    }

    private Mono<ResponseEntity<ApiResponse<String>>> saveNewUser(AddUserRequest request) {
        return userRepository.save(User.builder().uRole(request.getURole()).uName(request.getUName()).build())
                .flatMap(savedUser -> {
                    ApiResponse<String> response = new ApiResponse<>(MessagesUtils.SUCCESS, 
                            HttpStatus.CREATED.value(),
                            MessagesUtils.USER_ADDED_SUCCESSFULLY);
                    return Mono.just(ResponseEntity.status(HttpStatus.CREATED).body(response));
                });
    }

}

@RestController
@RequestMapping("/api/users")
@AllArgsConstructor
public class UserController {

    private UserManagementService userManagementService;

//  public UserController(UserManagementService userManagementService) {
//      this.userManagementService = userManagementService;
//  }

    @PostMapping()
    public Mono<ResponseEntity<ApiResponse<String>>> addUser(@RequestBody AddUserRequest addUserRequest){
        return userManagementService.addUser(addUserRequest);
    }
}
