Spring Boot Scheduler Made Easy | @Scheduled with Fixed Rate & Cron Examples
In this video José Cruz shows you how to use the Spring Boot Scheduler to run jobs on a schedule. You’ll see when to use it, when not to, and how to externalize timings with properties. We build a simple heartbeat job that runs every 5 seconds and explain `fixedRate`, `fixedDelay` and `cron` triggers, plus tips for production.
Whether you’re a beginner or an experienced Spring Boot developer, you’ll learn how to safely run scheduled tasks, avoid pitfalls, and plan the next steps for more advanced scheduling (cron expressions, cluster-safe jobs, observability).
