A number of things are being done here:
- We register the DispatcherServlet as as a Servlet called
appServlet - We map this Servlet to handle incoming requests (relative to the app path) starting with "/"
- We use the
ContextConfigLocationinit parameter to customize the location for the base configuration XML file for the Spring Application Context that is loaded by the DispatcherServlet, instead of relying on the default location of <servletname>-context.xml).
