In Spring it's easy to autowire beans and have them available anywhere in the app context. Beans can be specialized to a scope such as session/request/web socket etc.

I have a rather unique scenario. I receive a message from a message broker which means the request is not received in a "Controller". Because of this, Spring is not creating @RequestScope beans (All of this logic in Spring is based on using the @Controller/@RequestMapping annotations / DispatchServlet handler).
Is there a way to create a bean within the request scope with the Spring AutowireCapableBeanFactory or some other way?

I want to do something like the below in which the SomeService.handle will be able to access the getName() method of the RequestScopeBean. Currently it throws this exception.

Exception:

BeanCreationException: Error creating bean with name ' 

scopedTarget.getRequestUtils': Scope 'request' is not active for the 

current thread; consider defining a scoped proxy for this bean

Code

@Service

public class MyMessagingReceiver implements SomeMessageReceiver {



    private final SomeService someService;



    @Autowired

    public MyMessagingReceiver(final SomeService someService) {

        this.someService = someService;

    }



    public void onMessage(MessageObject messageObject) {

        //possible here to use AutowireCapableBeanFactory in inject the RequestScopeBean bean?

        someService.handle(messageObject);

    }

}



@Service

public class SomeService {



    private final RequestScopeBean requestScopeBean;



    @Autowired

    public SomeService(RequestScopeBean requestScopeBean) {

        this.requestScopeBean = requestScopeBean;

    }



    public void handle(MessageObject messageObject) {

        System.out.println(this.requestScopeBean.getName());

    }



}



@Configuration

public class BeanDeclarations {

    @Bean

    @RequestScope

    public RequestScopeBean requestScopeBean() {

        return new RequestScopeBean();

    }

}



public RequestScopeBean {

    private String name;



    public void setName(String name) {

        this.name = name;

    }



    public String getName() {

        return name;

    }

}



public class Interceptor extends HandlerInterceptorAdapter {

    private RequestScopeBean requestScopeBean;



    @Autowired

    public Interceptor(RequestScopeBean requestScopeBean) {

        this.requestScopeBean = requestScopeBean;

    }



    @Override

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        String name = request.getHeader("name");

        this.requestScopeBean.setName(name);

    }
