Interface BeanFactoryPostProcessor

All Known Implementing Classes:
CustomEditorConfigurer, PreferencesPlaceholderConfigurer, PropertyOverrideConfigurer, PropertyPlaceholderConfigurer, PropertyResourceConfigurer, ServletContextPropertyPlaceholderConfigurer

public interface BeanFactoryPostProcessor

Allows 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.
