我把FreeMarkerViewResolver的prefix配置为/WEB-INF/views/，就找不到对应界面了

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" id="viewResolver">
  <property name="viewResolvers">
     <list>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <property name="order" value="2"/>
           <property name="prefix" value="/WEB-INF/views/" />
           <property name="suffix" value=".jsp" />
        </bean>
        <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
           <property name="order" value="1"/>
           <property name="contentType" value="text/html;charset=UTF-8"/>
           <property name="cache" value="true"/>
           <property name="prefix" value=""/>
           <property name="suffix" value=".ftl"/>
           <property name="requestContextAttribute" value="request"/>
           <property name="exposeRequestAttributes" value="true"/>
           <property name="exposeSessionAttributes" value="true"/>
           <property name="exposeSpringMacroHelpers" value="true"/>
           <property name="allowSessionOverride" value="true"/>
        </bean>
     </list>
  </property>
</bean>
