spring - Problems with @Autowire annotation (null) -

i have problems 2 services autowired in validator class. services works ok because in controller autowired. i've applicationcontext.xml file , myapp-servlet.xml file. base package es.unican.meteo , have problems package es.unican.meteo.validator. package es.unican.meteo.controller , es.unican.meteo.service can autowire services properly.

applicationcontext.xml

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:context="http://www.springframework.org/schema/context"     xmlns:p="http://www.springframework.org/schema/p"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">  .... beans ... </beans> 

myapp-servlet.xml

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"  xmlns:context="http://www.springframework.org/schema/context"  xmlns:mvc="http://www.springframework.org/schema/mvc"  xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd   http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">      <!-- enabling spring beans auto-discovery -->     <context:component-scan base-package="es.unican.meteo" />      <!-- enabling spring mvc configuration through annotations -->     <mvc:annotation-driven /> 

class resetpasswordvalidator:

package es.unican.meteo.validator;   import org.springframework.beans.factory.annotation.autowired; import org.springframework.validation.errors; import org.springframework.validation.validator;  import es.unican.meteo.model.user; import es.unican.meteo.service.messageservice; import es.unican.meteo.service.userservice;  public class resetpasswordvalidation  implements validator{      @autowired     private userservice userservice;      @autowired     private messageservice messageservice;      public boolean supports(class<?> clazz) {         return user.class.equals(clazz);     }      public void validate(object target, errors errors) {         user user = (user)target;          if(userservice.getuserbyemail(user.getemail())==null){             errors.rejectvalue("email", messageservice.getmessage("app.error.nonexistentemail"));         }     } } 

i can see controllers, services , autowired elements in spring elements. seems spring not detecting autowired properties in package validator. ideas?

make sure annotate class spring picks bean. autowiring can occur on beans/classes managed di container.

adding @component cause class picked spring's component scanning, causing resetpasswordvalidation become bean. @ point, should eligible have fields autowired.

@component public class resetpasswordvalidation  implements validator
