I'm trying to have my code execute on a fixed schedule, based on a Spring cron expression. I would like the code to be executed every day at 1:01:am. I tried the following expression, but this didn't fire up for me. What's wrong with the syntax here?
我试图让我的代码按照固定的时间表执行，基于Spring cron表达式。我希望代码每天1：01：am执行。我尝试了以下表达式，但这对我来说并没有起作用。这里的语法有什么问题？
@Scheduled(cron = "0 1 1 ? * *")
public void resetCache() {
// ...
}

Try with:
试试：
@Scheduled(cron = "0 1 1 * * ?")
Below you can find the example patterns from the spring forum:
您可以在下面找到spring论坛的示例模式：
* "0 0 * * * *" = the top of every hour of every day.
* "*/10 * * * * *" = every ten seconds.
* "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
* "0 0 8,10 * * *" = 8 and 10 o'clock of every day.
* "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
* "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
* "0 0 0 25 12 ?" = every Christmas Day at midnight
Cron expression is represented by six fields:
Cron表达式由六个字段表示：
second, minute, hour, day of month, month, day(s) of week
(*) means match any
（*）表示匹配任何
*/X means "every X"
* / X表示“每X”
? ("no specific value") - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but I don't care what day of the week that happens to be, I would put "10" in the day-of-month field and "?" in the day-of-week field.
？ （“没有特定值”） - 当您需要在允许该字符的两个字段之一中指定某些内容时非常有用，而在另一个字段中则不需要。例如，如果我希望我的触发器在该月的某一天（例如，第10天）触发，但我不关心一周中的哪一天，我会在当天放置“10” - 月份字段和“？”在星期几的字段中。

For my scheduler, I am using it to fire at 6 am every day and my cron notation is:
对于我的调度程序，我每天早上6点使用它，我的cron表示法是：
0 0 6 * * *
If you want 1:01:am then set it to
如果你想要1：01：am然后将其设置为
0 1 1 * * *

@Scheduled(cron="0 1 1 * * *")

To be sure about the firing time correctness of your scheduler, you have to set zone value like this (I am in Istanbul):
为了确保调度程序的触发时间正确性，您必须设置像这样的区域值（我在伊斯坦布尔）：
@Scheduled(cron="0 1 1 * * *", zone="Europe/Istanbul")
public void doScheduledWork() {
//complete scheduled work
}

You can use annotate your method with @Scheduled(cron ="0 1 1 * * ?").
您可以使用@Scheduled（cron =“0 1 1 * *？”）注释您的方法。
0 - is for seconds
0 - 表示秒
1- 1 minute
1- 1分钟
1 - hour of the day.

Something missing from gipinani's answer
gipinani的回答中缺少一些东西
@Scheduled(cron = "0 1 1,13 * * ?", zone = "CST")
This will execute at 1.01 and 13.01. It can be used when you need to run the job without a pattern multiple times a day.
这将在1.01和13.01执行。当您需要每天多次运行没有模式的作业时，可以使用它。
And the zone attribute is very useful, when you do deployments in remote servers. This was introduced with spring 4.
当您在远程服务器中进行部署时，zone属性非常有用。这是在春季4推出的。

One thing i've noticed is: spring CronTrigger is not cron. You may end up with 7 parameters in a valid cron expression (wich you can validate on cronmaker.com) and then spring not accept it. Most of cases you just delete the last parameter and everything works fine.
我注意到的一件事是：Spring CronTrigger不是cron。您最终可能会在有效的cron表达式中使用7个参数（您可以在cronmaker.com上验证），然后不接受它。大多数情况下，您只需删除最后一个参数，一切正常。
