@H_301_1@如何编写cron表达式以在每个月的25日在早上9点开始触发一个函数？
当我执行此代码时,
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.Calendar.complete(Unknown Source)
java.util.Calendar.get(Unknown Source)
org.springframework.scheduling.support.CronSequenceGenerator.doNext(CronSequenceGenerator.java:130)
解决方法
@Scheduled(cron="0 9 25 1 * ?")
这只是1月1日,时间无效,你需要这个：
@Scheduled(cron="0 0 9 25 * ?")
