@FunctionalInterface public interface ServletContextInitializer
Interface used to configure a Servlet 3.0+contextprogrammatically. UnlikeWebApplicationInitializer, classes that implement this interface (and do not implementWebApplicationInitializer) will not be detected bySpringServletContainerInitializerand hence will not be automatically bootstrapped by the Servlet container.This interface is primarily designed to allow
ServletContextInitializers to be managed by Spring and not the Servlet container.For configuration examples see
WebApplicationInitializer.- Since:
- 1.4.0
