Spring-Boot multi module project load property-file

Question

I have a Spring-Boot-Application as a multimodule-Project in maven. The structure is as follows:

Parent-Project
|--MainApplication
|--Module1
|--ModuleN
<         


        

Answer 1

Autowiring is performed just after the creation of the object(after calling the constructor via reflection). So NullPointerException is expected in your constructor as tmdbConfig field would be null during invocation of constructor

You may fix this by using the @PostConstruct callback method as shown below:

@Component
public class TMDbWarper {

    @Autowired
    private TMDbConfig tmdbConfig;

    private TmdbApi tmdbApi;

    public TMDbWarper() {

    }

    @PostConstruct
    public void init() {
        tmdbApi = new TmdbApi(tmdbConfig.getApiKey());
    }

    public TmdbApi getTmdbApi() {
        return this.tmdbApi;
    }
}

Rest of your configuration seems correct to me.

Hope this helps.
