public class DefaultServletHttpRequestHandler extends Object implements HttpRequestHandler, ServletContextAware
An HttpRequestHandler for serving static files using the Servlet container's "default" Servlet.

This handler is intended to be used with a "/*" mapping when the DispatcherServlet is mapped to "/", thus overriding the Servlet container's default handling of static resources. The mapping to this handler should generally be ordered as the last in the chain so that it will only execute when no other more specific mappings (i.e., to controllers) can be matched.

Requests are handled by forwarding through the RequestDispatcher obtained via the name specified through the "defaultServletName" property. In most cases, the defaultServletName does not need to be set explicitly, as the handler checks at initialization time for the presence of the default Servlet of well-known containers such as Tomcat, Jetty, Resin, WebLogic and WebSphere. However, when running in a container where the default Servlet's name is not known, or where it has been customized via server configuration, the defaultServletName will need to be set explicitly.

    • handleRequest

      public Object handleRequest(RequestContext request) throws Throwable
      从接口复制的说明: HttpRequestHandler
      Process the request and return a result object which the DispatcherHandler will handle. A null return value is not an error: it indicates that this handler completed request processing itself and that there is therefore no explicit result to handle. a HttpRequestHandler.NONE_RETURN_VALUE indicates that no result to handle by ReturnValueHandler
      指定者:
      handleRequest 在接口中 HttpRequestHandler
      参数:
      request - Current request context
      返回:
      Result to be handled by ReturnValueHandler
      抛出:
      Throwable - If any exception occurred
