Package org.springframework.context

Interface ApplicationContextInitializer<C extends ConfigurableApplicationContext>

Type Parameters:

C - the application context type

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 ApplicationContextInitializer<C extends ConfigurableApplicationContext>

Callback interface for initializing a Spring ConfigurableApplicationContext prior to being refreshed.

Typically used within web applications that require some programmatic initialization of the application context. For example, registering property sources or activating profiles against the context's environment. See ContextLoader and FrameworkServlet support for declaring a "contextInitializerClasses" context-param and init-param, respectively.

ApplicationContextInitializer processors are encouraged to detect whether Spring's Ordered interface has been implemented or if the @Order annotation is present and to sort instances accordingly if so prior to invocation.

Since:

3.1
