Will a method annotated with @PostConstruct be guaranteed to execute prior to a method with @Scheduled within the same bean?

Question

Say I\'m defining a caching bean which will be initialized upon launch of the application and will be refreshed at a fixed interval as seen below:

@Component
pub         


        

Answer 1

Yes, the method annotated with @PostConstruct is guaranteed to execute first.

The @Scheduled annotation is activated by ScheduledAnnotationBeanPostProcessor.postProcessAfterInitialization() which is invoked after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
