Is it possible add a global @SingleUse for spring boot application?

Hope add global definition for spring-boot application. For example, if I add annotation at spring boot launch class, will guard all task execute once in nodes:

@SpringBootAppliction  
@EnableScheduling  
@SingleUse  

Thanks for any reply

Hi, thanks for feedback and sorry for the delay. If I understand you correctly, you want to add one annotation which would automatically put lock on all scheduled tasks? It is quite easy to implement but I am afraid that it’s a bit dangerous. We need a name for each lock and the only way to generated it automatically is to use method signature - ClassName.methodName(). In my opinion it’s quite fragile since you can rename the class or the method and when you deploy the change only to part of the cluster, the task will be executed twice. That’s why I hesitate to add it.

@zHaytam , yes it would and this is NOT the desired behaviour indeed. I have misread / misunderstood the initial request, so ignore my comment above.
