Frühjahr Autowiring-Service funktioniert nicht in meinem Controller

habe ich Probleme, um autowire einen Dienst in meinem controller. Ich habe diesen Fehler:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private es.unican.meteo.service.UserService es.unican.meteo.controller.MyController.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [es.unican.meteo.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)}

Scheint es, dass der userService ist nicht registriert, so dass der controller nicht die Bohne. Ich dachte, dass meine config war ok, denn es funktioniert mit den tests. In den tests habe ich dieses:

ClassPathXmlApplicationContext("/WEB-INF/app-config.xml");

und ich kann die Bohnen ok aus ApplicationContext.xml

Mein Paket-Struktur ist die folgende:

es.unican.meteo.controller

|---- MyController.java

es.unican.meteo.service

|---- UserService.java

es.unican.meteo.service.impl

|---- UserServiceImpl.java

.....

WebContent/WEB-INF

|---- MyDispatcherServlet-servlet.xml

|---- app-config.xml

|---- web.xml

.....

Den clases:

== UserServiceImpl.java ==

@Service
public class UserServiceImpl implements UserService{

    @Autowired
    private UserMapper userMapper;

    public void setUserMapper(UserMapper userMapper) {
        this.userMapper = userMapper;
    }

== MyController.java ==

@Controller
public class MyController {

     @Autowired
     private UserService userService;

     @RequestMapping(method=RequestMethod.GET, value="/home")
     public String handleRequest(){
      return "welcome";
     }

     @RequestMapping(method=RequestMethod.GET, value="/getUsers")
     public @ResponseBody List<User> getUsersInJSON(){
      return userService.getUsers();
     }
}

== web.xml ==

Habe ich überprüft, einige Fragen zu diesem Thema, aber ich finde nicht die Lösung zu meinem problem. Vielleicht habe ich überspringe etwas, aber ich weiß nicht, sicherlich. Ich habe versucht, ändern Sie die Komponente-scan mit keine Ergebnisse.

Wenn ich versuche, Zugriff auf /SPRING-MVC/getUsers.gehen scheint, diese Fehler.

Ich weiß nicht, ob die Bohnen gelegt werden muss, in app-config (Datei ApplicationContext) oder in der servlet.xml da ist es ein bisschen verwirrend...

Danke
