Interface Condition

  • All Known Subinterfaces:
    ConfigurationCondition
    public interface Condition
    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 BeanFactoryPostProcessor and take care to never interact with bean instances. For more fine-grained control of conditions that interact with @Configuration beans consider the ConfigurationCondition interface.
