public class ServletForwardingController extends AbstractController implements cn.taketoday.beans.factory.BeanNameAware, ServletContextAware
Controller implementation that forwards to a named servlet, i.e. the "servlet-name" in web.xml rather than a URL path mapping. A target servlet doesn't even need a "servlet-mapping" in web.xml in the first place: A "servlet" declaration is sufficient.

Useful to invoke an existing servlet via Framework's dispatching infrastructure, for example to apply Framework HandlerInterceptors to its requests. This will work even in a minimal Servlet container that does not support Servlet filters.

Example: web.xml, mapping all "/myservlet" requests to a Framework dispatcher. Also defines a custom "myServlet", but without servlet mapping. 

 <servlet>
   <servlet-name>myServlet</servlet-name>
   <servlet-class>mypackage.TestServlet</servlet-class>
 </servlet>

 <servlet>
   <servlet-name>myDispatcher</servlet-name>
   <servlet-class>cn.taketoday.web.servlet.DispatcherServlet</servlet-class>
 </servlet>

 <servlet-mapping>
   <servlet-name>myDispatcher</servlet-name>
   <url-pattern>/myservlet</url-pattern>
 </servlet-mapping>
Example: myDispatcher-servlet.xml, in turn forwarding "/myservlet" to your servlet (identified by servlet name). All such requests will go through the configured HandlerInterceptor chain (e.g. an OpenSessionInViewInterceptor). From the servlet point of view, everything will work as usual. 
 <bean id="myServletForwardingController" class="cn.taketoday.web.servlet.mvc.ServletForwardingController">
   <property name="servletName"><value>myServlet</value></property>
