I want to integrate Spring with Hibernate. I am new to both technologies. At the moment I get an error like this:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: public service.UserService controller.HomeController.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
Can anybody help me, please?

@Controller
public class HomeController {
@Autowired
private UserService userService;
@RequestMapping("/register")
public ModelAndView getRegisterForm(@ModelAttribute("user") User user,
BindingResult result) {
