Spring Boot @EnableScheduling conditionally
I Solved this, here is what I did for future reference:
- Removed @EnableScheduling annotation from my app
- Added a new configuration class and conditional to enable/disable scheduling based on an application property
-
@Configuration
public class Scheduler {
@Conditional(SchedulerCondition.class)
@Bean(name = TaskManagementConfigUtils.SCHEDULED_ANNOTATION_PROCESSOR_BEAN_NAME)
@Role(BeanDefinition.ROLE_INFRASTRUCTURE)
public ScheduledAnnotationBeanPostProcessor scheduledAnnotationProcessor() {
return new ScheduledAnnotationBeanPostProcessor();
}
}
And the conditional class
public class SchedulerCondition implements Condition {
@Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
return Boolean.valueOf(context.getEnvironment().getProperty("com.myapp.config.scheduler.enabled"));
}
}
Also, to disable web server on the backend server, just add the following to the application.properties file:
spring.main.web_environment=false
You can annotate a bean injection like this:
@Bean
@ConditionalOnProperty(prefix = "your.property", name = "yes", matchIfMissing = true)
public void doSomeBackendJob() {
/* job implementation here */
}
Bonus: Since you want to run different things in different machines, i.e., you will deploy the same app with different configurations, you could use spring profiles, if that's the case you can annotate a class or method like this:
@Component
@Profile({ Constants.SPRING_PROFILE_PRODUCTION, Constants.SPRING_PROFILE_TEST })
public class TheClass{...}
