Hands-On Cloud-Native Applications with Java and Quarkus

Firing one-time events

If you need to execute one-time events, then you can inject the io.quarkus.scheduler.Scheduler class into your code directly and use the startTimer method, which will fire the execution of an action in a separate thread. This can be seen in the following example:

@InjectScheduler scheduler;public void oneTimeEvnt() {    scheduler.startTimer(300, () -> oneTimeAction());    }public void oneTimeAction() {    // Do something}

In this brief excerpt, we can see how a single event, which will be executed in the oneTimeAction() method, can fire a one-time action after 300 milliseconds.
