Cron 表达式在每月 25 日触发
如何编写 cron 表达式以在每月 25 日早上 9 点触发函数？
当我执行这段代码时，
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;
@Service
public class PayrollSchedulerImpl implements PayrollScheduler{
@Scheduled(cron="0 9 25 1 * ?")
public void calculateSalaryScheduled()
{
calculateSalary();
}
public void calculateSalary()
{
/* */
}
}
我收到错误，
java.lang.StackOverflowError
sun.util.calendar.ZoneInfo.getOffsets(Unknown Source)

java.util.GregorianCalendar.computeFields(Unknown Source)

java.util.Calendar.updateTime(Unknown Source)
java.util.Calendar.complete(Unknown Source)
java.util.Calendar.get(Unknown Source)

参考：
CronSequenceGeneratorThis is on January 1st only, and the time is invalid, you'll want this instead:
