I have to generate a set of beans in a @Configuration class with the @PostConstruct and BeanFactoryAware.
Something like this:
@Configuration
public class MyBeansConfiguration implements BeanFactoryAware {
@Setter
private BeanFactory beanFactory;
@PostConstruct
public void beanGenerator(){
ConfigurableBeanFactory configurableBeanFactory = (ConfigurableBeanFactory) beanFactory;
configurableBeanFactory.registerSingleton("a", new AClass())
}
@Bean
public BClass b() {
return new BClass();
}
}
The service:
@Service
public class MyServiceImpl {
private final AClass a;
private final BClass b;
@Autowired
public MyServiceImpl(AClass a, BClass b){
this.a = a;
this.b = b;
}
}
When I try to start the application, the AClass bean cannot be loaded and I get this error:
Parameter 0 of constructor in com.acme......MyServiceImpl required a bean of type 'com.acme....BClass' that could not be found.
The funny thing is that when I try to inject my beans changing the order, the application star successfully without any problems.
@Autowired
public MyServiceImpl(BClass b, AClass a){
this.a = a;
this.b = b;
}
Why is this happening?
