Class DefaultServletHandlerConfigurer

java.lang.Object

org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer

public class DefaultServletHandlerConfigurer
extends Object

Configures a request handler for serving static resources by forwarding the request to the Servlet container's "default" Servlet. This is intended to be used when the Spring MVC DispatcherServlet is mapped to "/" thus overriding the Servlet container's default handling of static resources.

Since this handler is configured at the lowest precedence, effectively it allows all other handler mappings to handle the request, and if none of them do, this handler can forward it to the "default" Servlet.

Since:

3.1
