看帖子评论找到的方法：帖子地址：http://hbxflihua.iteye.com/blog/2320584

<!-- 配置RedisCacheManager -->
 <bean id="redisCacheManager" class="org.springframework.data.redis.cache.RedisCacheManager"> 
     <constructor-arg name="redisOperations" ref="redisTemplate" />
  <property name="defaultExpiration" value="${redis.expiration}"/>
        <property name="expires"> 
            <util:map> 
                <entry value="180" key="selectUserById"/> 
                <entry value="180000" key="menuByUrl"/> 
            </util:map> 
        </property> 
 </bean>
