类 DefaultServletHandlerConfigurer

java.lang.Object

cn.taketoday.web.config.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 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.

enable

public void enable()

Enable forwarding to the "default" Servlet.

When this method is used the DefaultServletHttpRequestHandler will try to autodetect the "default" Servlet name. Alternatively, you can specify the name of the default Servlet via enable(String).

enable

public void enable(@Nullable
 String defaultServletName)

Enable forwarding to the "default" Servlet identified by the given name.

This is useful when the default Servlet cannot be autodetected, for example when it has been manually configured.
