这是Spring IOC的正确/预期用途吗？

Question

实例化域对象的常规做法是什么？假设在如下的体系结构中：

@RestController
public class MyController implements ServletConfigAware {

        private ApplicationContext context;


        @RequestMapping(value="/getNewObject")
        public MyBusinessObject getANewObject(){

             MyService service = (MyService)context.getBean("myService);
             return service.getNewObject();

        } 

public class MyService {

        private ApplicationContext context;            

        public MyBusinessObject getNewObject(){

             return new MyBusinessObject();

                     vs

             (MyBusinessObject)context.getBean("myBusinessObject");

                     vs

             (MyBusinessObject)context.getBean("myBusinessObjectFactory").createNewMyBusinessObject();  //Factory is another class which returns a 'new' object
        }

}

public class MyBusinessObject { }

我是否以预期的方式使用弹簧IOC？
