How to Access Static Resources When Using a Global Front Controller Servlet Mapped on /*?

Accessing Static Resources with a Global Front Controller Servlet Mapped on /*

When using a global front controller servlet such as the Spring MVC DispatcherServlet mapped on /*, accessing static resources like CSS, JavaScript, and images can become an issue. This mapping essentially intercepts all incoming requests, potentially preventing access to resources stored outside the controller scope.

To resolve this, consider mapping the controller servlet on a more specific url-pattern, for instance, /pages/*. This will allow the controller to handle requests for specific pages while leaving other paths open for static resource access.

Secondly, place the static content in a dedicated folder, such as /static. This separation will facilitate resource management and prevent conflicts with the controller's content.

Finally, create a Filter listening on /* that handles both static and dynamic requests transparently. In the filter's doFilter() method, examine the request URI to determine if it belongs to a static resource.

If it does (e.g., starts with "/static"), forward the request to the default servlet for processing. Otherwise, if the request belongs to the controller's scope (i.e., starts with "/pages"), forward it to the appropriate page-handling dispatcher.

This approach allows for seamless access to both static and dynamic resources while preserving the intended functionality of the global front controller servlet.
