 <!--2、配置redis连接工厂-->

  System.out.println(name);
  System.out.println("操作完成");

 <!--3、配置redis模板对象-->
 <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">

  <!--配置String类型的key value序列化方式 当存储的key是String类型时，则vlaue也是String类型，且key和value不被序列化-->
  <property name="keySerializer" ref="stringRedisSerializer"/>
  <property name="valueSerializer" ref="stringRedisSerializer"/>

 <!--自定义序列化类型-->
