春天cron表达每30分钟后 [英] Spring cron expression every after 30 minutes

问题描述

Java spring - 我有cron工作的cron表达式。

  0 0/35 * * *？但是上面提到的cron表达式在一小时内触发一次，如下所示：
 
 
 
 
 
 < b 
 
 1:35 
 2:35 
 3:35 
 4:35 
 
 
 
我想
解决方案
 > 
 Cron语法是
 秒分钟小时day_of_month month day_of_week年
  
 
 
 
所以你想要的是
  0 0 ，35 * * * *？ 
  
所以它会在每小时0分和35分钟触发。
 
 
 
有关详情，请参阅 Quartz文档，如Spring正在使用Quartz作为调度程序。这些文档还解释特殊的字符*。 - ，和其他。
 
Java spring - I have following cron expression for cron job.
0 0/35 * * * ?
But above mentioned cron expression fires once in an hour and like as follows

1:35
2:35
3:35
4:35

I want to fire every after 35 mins instead once in an hour

any quick suggestion ?
解决方案
Cron syntax is 
sec min hour day day_of_month month day_of_week year
So what you would want is
0 0,35 * * * * ?
So it will fire on minutes 0 and 35 of each hour.

See the Quartz docs for this, as Spring is using Quartz as scheduler here. Those docs also explain the special chars like * ? - , and others.
