Sto provando a gestire il login alla mia applicazione tramite i social, e quindi usare il framework messo a disposizione da spring.

pero` ho dei problemi:

ora vi copio un po` di codice cosi` ci capiamo
questo e` il controller
codice:
package com.pharmawizardcabinet.core.controller.social;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.security.crypto.encrypt.Encryptors;
import org.springframework.social.connect.UsersConnectionRepository;
import org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository;
import org.springframework.social.connect.support.ConnectionFactoryRegistry;
import org.springframework.social.facebook.api.Facebook;
import org.springframework.social.facebook.api.PagedList;
import org.springframework.stereotype.Component;


@Component("socialManager")
public class SocialManager {


    @Autowired
    @Qualifier("connectionFactoryLocator")
    ConnectionFactoryRegistry connectionFactoryLocator;


    private Facebook facebook;


    public SocialManager() {


    }


    public SocialManager(Facebook facebook) {
        this.facebook = facebook;
    }


    public String getInfo() {
        return facebook.userOperations().getUserProfile().getEmail();
    }




    public PagedList<String> getPermission() {
        return facebook.userOperations().getUserPermissions();
    }
    public Facebook getFacebook() {
        return facebook;
    }


    public void setFacebook(Facebook facebook) {
        this.facebook = facebook;
    }




}
questo e` il bean
codice:
<?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:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">




    <bean id="connectionFactoryLocator"
        class="org.springframework.social.connect.support.ConnectionFactoryRegistry">
        <property name="connectionFactories">
            <list>
                <bean
                    class="org.springframework.social.facebook.connect.FacebookConnectionFactory">
                    <constructor-arg value="${spring.social.facebook.appid}" />
                    <constructor-arg value="${spring.social.facebook.secretkey}" />
                </bean>
            </list>
        </property>
    </bean>






</beans>
questo e` il servizio restful
codice:
@RequestMapping(value = "/signup/facebook", method = RequestMethod.POST)
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public @ResponseBody
    ResponsePWCabinet registerUserFacebook(@RequestBody String token) {
        logger.debug("[registerUserFacebook] token: " + token);
        socialManager.setFacebook(new FacebookTemplate(token));
        logger.debug("[registerUserFacebook] socialManager.getInfo(): " + socialManager.getPermission());
        return ResponsePWCabinet.build(Risposta.KO, Risposta.USER_EXIST.toString());


    }

ma mi va` in errore e mi risponde codesta cosa

codice:
{"error":{"message":"Invalid OAuth access token.","type":"OAuthException","code":190}}
qualcuno ha idea del perche`?
