Spring 调度 - 每天午夜的 Cron 表达式不起作用? [英] Spring Scheduling - Cron expression for everyday at midnight not working?

问题描述

我正在尝试在 Spring 中安排一项每天午夜运行的任务.我遵循了 Spring 的 官方指南 并制作了如下调度程序类:

I am trying to schedule a task in Spring which is to be run everyday at midnight. I followed the official guide from Spring and made the scheduler class as below:

@Component
public class OverduePaymentScheduler {    
    @Scheduled(cron = "0 0 0 * * *")
    public void trackOverduePayments() {
        System.out.println("Scheduled task running");
    }
}

但是，当时钟到达凌晨 12 点时，任务不会运行.我从这个 链接的石英调度器文档中得到了 cron 表达式.

However the task does not run when the clock hits 12am. I got the cron expression from the documentation for quartz scheduler at this link.

如果我将 cron 表达式更改为*/10 * * * * *"，则调度程序执行良好；每十秒运行一次.

The scheduler is executed fine if I change the cron expression to "*/10 * * * * *" which runs every ten seconds.

那我做错了什么?

推荐答案

我终于让它与这个 cron 表达式 0 0 0 * * * 一起工作，但我不得不在这样的调度程序类.@Scheduled(cron = "0 0 0 * * *",zone = "印度/马尔代夫")

I finally got it to work with this cron expression 0 0 0 * * * but I had to set the time zone in the scheduler class like this. @Scheduled(cron = "0 0 0 * * *",zone = "Indian/Maldives")
