Microservice Development: Creating User-Service which is responsible for Managing users

Comment

With microservices there are both benefits and downsides, so we had to evaluate if they are right for us. The most important consideration was that given the large scale of the application, we needed the possibility to split all functionality into small chunks and easily disable or enable specific functionality based on different variables.

@Service
public class UserService {

    @Autowired
    private UserRepository userRepository;

    public Flux<UserDto> all(){
        return this.userRepository.findAll()
                    .map(EntityDtoUtil::toDto);
    }

    public Mono<UserDto> getUserById(final int userId){
        return this.userRepository.findById(userId)
                    .map(EntityDtoUtil::toDto);
    }

    public Mono<UserDto> createUser(Mono<UserDto> userDtoMono){
        return userDtoMono
                    .map(EntityDtoUtil::toEntity)
                    .flatMap(this.userRepository::save)
                    .map(EntityDtoUtil::toDto);
    }

    public Mono<UserDto> updateUser(int id, Mono<UserDto> userDtoMono){
        return this.userRepository.findById(id)
                .flatMap(u -> userDtoMono
                                .map(EntityDtoUtil::toEntity)
                                .doOnNext(e -> e.setId(id)))
                .flatMap(this.userRepository::save)
                .map(EntityDtoUtil::toDto);
    }

    public Mono<Void> deleteUser(int id){
        return this.userRepository.deleteById(id);
    }

}
