How to conditionally enable or disable scheduled jobs in Spring?

Question

I am defining scheduled jobs with cron style patterns in Spring, using the @Scheduled annotation.

The cron pattern is stored in a config properties file

Answer 1

If you are looking to toggle @EnableScheduling from a property you can do this in Spring Boot by moving the @EnableScheduling annotation to a configuration class and use @ConditionalOnProperty as follows:

@Configuration
@EnableScheduling
@ConditionalOnProperty(prefix = "com.example.scheduling", name="enabled", havingValue="true", matchIfMissing = true)
public class SchedulingConfiguration {

}

This will disable scheduling for the application. This may be useful in a situation where you want to be able to run the application once or scheduled depending on how it's being started.
