- All Known Subinterfaces:
- BeanDefinitionRegistryPostProcessor
- All Known Implementing Classes:
- AspectJWeavingEnabler, ConfigurationClassPostProcessor, CustomAutowireConfigurer, CustomEditorConfigurer, CustomScopeConfigurer, DeprecatedBeanWarner, EventListenerMethodProcessor, PlaceholderConfigurerSupport, PreferencesPlaceholderConfigurer, PropertyOverrideConfigurer, PropertyPlaceholderConfigurer, PropertyResourceConfigurer, PropertySourcesPlaceholderConfigurer
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface BeanFactoryPostProcessorAllows for custom modification of an application context's bean definitions, adapting the bean property values of the context's underlying bean factory.Application contexts can auto-detect BeanFactoryPostProcessor beans in their bean definitions and apply them before any other beans get created.
Useful for custom config files targeted at system administrators that override bean properties configured in the application context.
See PropertyResourceConfigurer and its concrete implementations for out-of-the-box solutions that address such configuration needs.
A BeanFactoryPostProcessor may interact with and modify bean definitions, but never bean instances. Doing so may cause premature bean instantiation, violating the container and causing unintended side-effects. If bean instance interaction is required, consider implementing
BeanPostProcessorinstead.- Since:
