Imports

org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.core.type.AnnotatedTypeMetadata

A single condition that must be matched in order for a component to be registered.

Conditions are checked immediately before the bean definition is due to be registered and are free to veto registration based on any criteria that can be determined at that point.

Conditions must follow the same restrictions as a BeanFactoryPostProcessor and take care to never interact with bean instances. For more fine-grained control over conditions that interact with @Configuration beans, consider implementing the ConfigurationCondition interface.

Multiple conditions on a given class or on a given method will be ordered according to the semantics of Spring's org.springframework.core.Ordered interface and @Order annotation. See org.springframework.core.annotation.AnnotationAwareOrderComparator for details.
