如何将usercache与自定义daoauthenticationprovider一起使用

我需要使用spring提供的usercache,但似乎无法使其工作。据我所知,我甚至认为我在使用它时将其作为daoAuthenticationProvider(我试图使用它的功能)中的引用来获取userdetails服务的实现。我做了以下事情:

1)使用我自己的HibernateDao实现UserDetailsInterface

2)按照第1点的规定提供了我自己的loadbyusername(String username)方法

3)配置我的app-context:

                                            

<beans:bean id="encoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder"/>

<beans:bean id="userCache" class="org.springframework.security.core.userdetails.cache.EhCacheBasedUserCache">
    <beans:property name="cache" ref="userCacheBackend"/>
</beans:bean>   

<beans:bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
     <beans:property name="configLocation" value="classpath:/ehcache.xml"/>
</beans:bean>

<beans:bean id="userCacheBackend" class="rg.springframework.cache.ehcache.EhCacheFactoryBean">
    <beans:property name="cacheManager" ref="cacheManager"/>
    <beans:property name="cacheName" value="userCache"/>
</beans:bean>

<authentication-manager>
    <authentication-provider user-service-ref="userDao">
        <password-encoder ref="encoder" /> 
    </authentication-provider>
</authentication-manager>

<beans:bean id="daoAuthenticationProvider"
        class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
        <beans:property name="userDetailsService" ref="userDao"/>
        <beans:property name="passwordEncoder" ref="encoder"/> 
        <beans:property name="userCache" ref="userCache"/>
</beans:bean>

然而,尽管我将userDao设置为userDetailsS​​ervice属性名称,但我似乎无法使用DaoAuthenticationProvider和AbstractUserDetailsAuthenticationProvider类提供的任何功能来实现UserDetailsS​​ervice接口(这将是我的HibernateDao)。

这是我的hibernate dao:

@Repository("userDao")
public class HibernateUserDao extends HibernateBaseDao<User, Long> implements
    UserDao, UserDetailsService{ etc ....................

@Transactional

public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {

    logger.warn(" loadByUserName has been invoked for username " + username);
    List users = getSessionFactory().getCurrentSession().
            createQuery("from User where username=?")
            .setParameter(0, username).list();
    if (users == null || users.isEmpty()) {
        throw new UsernameNotFoundException("user '" + username
                + "' not found...");
    } else {
        return (UserDetails) users.get(0); 
    }
}

我做的事真的很蠢吗?请帮助我疯了。
