1.3. 使用与更新 ，默认select全部使用
Select应该搞个白名单。。Update不需要，使用定期模式，因为他是根据mapper已有up操作 就清空缓存了意义不大。。
1.4. Redis gui

String parameter = cliSendAdviceDao.getParameter(map);
//ati set cache
MybatisCacheAbs1.putObjectByThrdlocalCurKey_AsynProxy("getParameter",parameter);
// new MybatisRedisCache().putObjectByThrdlocalCurKey("getParameter",parameter);
//end set cache finish
