I would want to enable my new feature based on a database value . If the database value is set for the feature , the new code should be enabled. Else it should toggle and flow to the old code. is there a way to accomplish this in Java/Spring ? I do not want to hit the database frequently.I am thinking of one call at the start of the request . Are there any examples to this ? If so please let me know. Thanks
Create Feature class implementation:
public enum CustomFeatures implements Feature {
@Label("Activates customFeature")
MY_CUSTOM_FEATURE;
public boolean isActive() {
return FeatureContext.getFeatureManager().isActive(this);
}
}
Create feature provider:
@Bean
public FeatureProvider featureProvider() {
return new EnumBasedFeatureProvider(CustomFeatures.class);
}
Create entity and repository:
@Entity
public class Feature {
private String name;
private Boolean active;
// getters-setters
}
Create @Component which will query database and sets new feature sate
@Component
public class FeatureToggler {
private final FeatureRepository featureRepository;
private final FeatureManager featureManager;
private FeatureToggler(FeatureRepository featureRepository, FeatureManager featureManager) {
this.featureRepository = featureRepository;
this.featureManager = featureManager;
}
@Schedule(fixedRate=60000)
public void refreshFeatureToggles() {
featureManager.setFeatureState(new FeatureState(CustomFeatures.MY_CUSTOM_FEATURE, featureRepository.findByName().isActive);
}
}
Now you could use check if feature enabled like this:
if(CustomFeatures.MY_CUSTOM_FEATURE.isActive()) {
}
Or use Spring aspect..
