Hi,
I'm beginner with spring quartz and i have a problem for my project.
I'would whan my job is failed or sleep, the scheduler relance it and the job can retake
where it has stopped.
This is a differents steps how i was did :
In the first i have m y class scheduler:
Code:
@DisallowConcurrentExecution
