Spring Cron Every 5 Minutes

In Spring Boot, the @Scheduled annotation uses a 6-field cron format that includes seconds. The expression for every 5 minutes is:

Note the leading `0` — this is the seconds field, which must be present in Spring cron. The fields are: `second minute hour day-of-month month day-of-week`. Forgetting the seconds field is the most common mistake when migrating from standard cron.

Spring also offers `fixedRate` and `fixedDelay` as simpler alternatives: `@Scheduled(fixedRate = 300000)` runs every 5 minutes (300,000 milliseconds). Use `fixedRate` for simple intervals and cron expressions for complex schedules. Spring's cron also supports timezone configuration via the `zone` attribute: `@Scheduled(cron = "0 */5 * * * *", zone = "America/New_York")`.
