在应用程序启动后和午夜之后运行的Spring Scheduler [英] Spring scheduler which is run after application is started and after midnight

问题描述

如何描述在应用程序启动后和00:00之后运行的Spring调度程序?

How to describe Spring scheduler which is run after application is started and after 00:00 ?

推荐答案

我将使用两个单独的结构来做到这一点.

I would do this with two separate constructs.

对于在应用程序启动之后，请使用 @PostConstuct ，对于每天午夜的午夜，请使用设置了 cron 值的 @Scheduled .两者都应用于方法.

For after the application starts, use @PostConstuct, and for every night at midnight use @Scheduled with the cron value set. Both are applied to a method.

public class MyClass {
    @PostConstruct
    public void onStartup() {
        doWork();
    }

    @Scheduled(cron="0 0 0 * * ?")
    public void onSchedule() {
        doWork();
    }

    public void doWork() {
        // your work required on startup and at midnight
    }
}
