Spring @scheduled with cron but no overlapping crons

Question

Hi I would like A cronjob to be run within spring but I also need to make sure that they don't overlap when running is this possible. Using spring boot 5.1

@Scheduled(cron="${con}", fixedDelay = 5000)
 public void run(){
     some method
 }

this obviously fails is there some way to obtain this

Answer 1

By default, spring uses a single-threaded Executor. so no two @Scheduled tasks will ever overlap.

Answer 2

您可以检查先前的run方法是否已完成，而不是配置不重叠的cron，如果尚未完成，则退出run（）函数。
