after migrating from spring 3 to 5 i can’t do this anymore in a rest controller:

@Lazy
@Controller
@RequestMapping("/Portability4CtRestService")
public class Portability4CtRestService extends AbstractP4CtRestService {

    private P4CtAccountRoutingService accountRoutingService;

    /**
     * @param accountRoutingService the accountRoutingService to set
     */
    @Autowired
    public void setAccountRoutingService(P4CtAccountRoutingService p4ctAccountRoutingService) {
        this.accountRoutingService = p4ctAccountRoutingService;
    }

    @RequestMapping(value = "/searchAccountRouting", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
    public @ResponseBody
    String searchAccountRouting(HttpServletRequest request) {
        
            //do something with accountRoutingService....

    }
}

the objet autowired with @Autowired annotation is always null, the same happens if i use

@Autowired
private P4CtAccountRoutingService accountRoutingService;

or 

@Resources
private P4CtAccountRoutingService accountRoutingService;

A possible workaround is to make something like this in the costructor:

public Portability4CtRestService() {
        setAccountRoutingService((P4CtAccountRoutingService) it.vtfinance.vtpie.core.configuration.spring.ContextSupport.getContext().getBean(P4CtAccountRoutingService.BEAN_NAME));
    }

But i wondering if this is the right way and why i can’t use anymore spring annotation to call a spring bean.
