org.springframework.context.annotation.Condition

A single {@code condition} that must be {@linkplain #matches matched} in orderfor 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 {@link BeanFactoryPostProcessor}and take care to never interact with bean instances. For more fine-grained control of conditions that interact with {@code @Configuration} beans consider the{@link ConfigurationCondition} interface. @author Phillip Webb @since 4.0 @see ConfigurationCondition @see Conditional @see ConditionContext
