ServletContextInitializer (Spring Boot API)

All Known Implementing Classes:
AbstractFilterRegistrationBean, DelegatingFilterProxyRegistrationBean, DynamicRegistrationBean, FilterRegistrationBean, RegistrationBean, ServletListenerRegistrationBean, ServletRegistrationBean
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 ServletContextInitializer
```
Interface used to configure a Servlet 3.0+ context programmatically. Unlike WebApplicationInitializer, classes that implement this interface (and do not implement WebApplicationInitializer) will not be detected by SpringServletContainerInitializer and 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
