1.低级写法:
if (null != redisCacheService.get(MediaConstants.GUANGDIANTONG_YOUMI + CommonConstants.PLUS
+ md5_idfa)) {
guandianTong =redisCacheService.get(MediaConstants.GUANGDIANTONG_YOUMI + CommonConstants.PLUS
+ md5_idfa);
redisCacheService.del(MediaConstants.GUANGDIANTONG_YOUMI + CommonConstants.PLUS + md5_idfa);
}
