Java - @Autowire pas de paramètre DAO - Stack Overflow

I have the following Spring Java configuration set up:

@Configuration
public class FooConfig {
    @Autowired
    private IReferenceDataDAO referenceDataDAO;

    @Bean
    public IReferenceDataService getReferenceDataService() {
        return new ReferenceDataServiceImpl(referenceDataDAO);
    }
}

I am trying to reference the ReferenceDataService bean in another configuration class using the @Autowire property:

@Configuration
public class BarConfig {

    @Autowired
    private IRuleService ruleService;

    @Autowired
    private IReferenceDataService referenceDataService;
}

Here is the config that defines the IReferenceDataDAO:

@Configuration
public class FooBarConfig {

@Bean
public IReferenceDataDAO getReferenceDataDAO() {
    return new ReferenceDataDAOImpl(getStaticData(), getMapper());
    }
}

Here is the ReferenceDataServiceImpl:

public class ReferenceDataServiceImpl implements IReferenceDataService {

   private IReferenceDataDAO dao;

public ReferenceDataServiceImpl(IReferenceDataDAO dao) {
    this.dao = dao;
}

The above configs are imported in a master config class:

@Configuration
@Import({
    FoosAppConfig.class,
BarAppConfig.class,
FooBarAppConfig.class,
})

I am noticing that this configuration leads to the referenceDAO in the ReferenceDataServiceImpl being set to null. What am I doing wrong? Shouldn't that @Autowire annotation ensure that my bean is fully configured before setting it?

BarConfig needs to import FooConfig @Import({ FooConfig.class })

Try this:

@Configuration
@Import({ FooConfig.class })
public class BarConfig {

    @Autowired
    private IRuleService ruleService;

    @Autowired
    private IReferenceDataService referenceDataService;
}

This allows BarConfig to get access to the IReferenceDataService bean.
