# General
This project demonstrates the tracking of scheduled jobs using Spring AOP.
The tracking is fairly simple. The `ScheduledJobTrackingAspect` invokes every method with an `Scheduled` annotation and writes the start and end of the method into the `ScheduledJobTracker`.
A UUID is assigned to the job upon start, since a single job can run multiple times at once.
The data is available via `ScheduledJobController`.
This is just a project demonstrating the tracking. I am considering to build a library that can be included in any spring boot project to enable tracking of scheduled tasks.
## Sample scheduled job
The demo has a very simple scheduled job, that prints *foo* every 5 seconds.
```kotlin
package com.example.demo
import org.springframework.scheduling.annotation.Scheduled
import org.springframework.stereotype.Component
@Component
class ScheduledJob {
@Scheduled(fixedRate = 5000)
fun println() = println("foo")
}
```
## Access data via REST
`GET /scheduled-jobs/`
