nested exception is io.lettuce.core.RedisCommandExecutionException: ERR invalid expire time in setex_error in execution; nested exception is io.lettuce

线上时不时会报出类似的报错，看代码以为key为空取值问题，结果本地调试后发现并不是，于是通过打印详细报错找到了大概方向。

错误信息: Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: ERR invalid expire time in setex
org.springframework.data.redis.RedisSystemException: Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: ERR invalid expire time in setex

字面意思是set过期时间那出现了问题，因为业务需要一些key需要在0点过期，在set过期时间时用秒做单位，用当天23:59:59减当前时间除1000算秒，结果出现0的情况。本地写了个测试代码调试，发现过期时间不能为小于等于0的数值。引以为戒吧，没准面试时候也会被问到。

String key = RedisKeys.getUserTodayScoreKey(6);

stringRedisTemplate.opsForValue().set(key, "0", 0, TimeUnit.SECONDS);
