<bean id="accessDecisionManager"
    class="org.springframework.security.vote.AffirmativeBased">
  <property name="allowIfAllAbstainDecisions" value="false" />
  <property name="decisionVoters">
    <list>

role은 "ROLE_"로 시작해야 한다.(error point) 

다른 role을 사용하는 시스템에 

Spring Security를 연결하는 경우 

Access Decision Manager를 정의, 

RoleVoter에 prefix를 재설정한다
