Cron Jobs Are Dead: How I Used Temporal to Future-Proof My Spring Boot App
Let’s face it — cron jobs are fragile. They fail silently, don’t retry intelligently, and vanish without a trace when your server crashes at 2 AM. For years, I relied on @Scheduled tasks in my Spring Boot apps, patching them with logging, retries, and monitoring scripts. But the deeper I went into production-scale scheduling, the more it felt like building a rocket out of duct tape.
That’s when I discovered Temporal — a game-changing workflow engine that made my old cron setup feel like a relic.
In this article, I’ll show you how I replaced every cron job in my Spring Boot app with durable, observable, fault-tolerant workflows using Temporal — and why I believe cron jobs are officially dead.
If you’re tired of missed runs, manual retries, and sleepless nights watching your batch jobs like a hawk — this is the upgrade your backend needs.

Before we dive into the solution, let’s look at the common issues I faced:
- Silent Failures: If a job throws an exception and no alerting is configured, it’s easy to miss. Cron won’t retry it.
- Lack of Resilience: Server restarted? Cron was supposed to run 5 minutes…
