case insensitive mapping for Spring MVC @RequestMapping annotations [duplicate]

Answer 1

The following simple solution should make @RequestMapping insensitive, whether it annotates a Controller or a method. Biju's solution should work too.

Create this custom HandlerMapping :

public CaseInsensitiveAnnotationHandlerMapping extends DefaultAnnotationHandlerMapping {

    @Override
    protected Object lookupHandler(String urlPath, HttpServletRequest request)
                    throws Exception {

        return super.lookupHandler(urlPath.toLowerCase(), request);
    }

    @Override
    protected void registerHandler(String urlPath, Object handler)
                    throws BeansException, IllegalStateException {

        super.registerHandler(urlPath.toLowerCase(), handler);
    }

}

And add this in your [servlet-name]-servlet.xml :

Note: if you don't want two HandlerMapping in your app, you may want to remove (it instantiates a DefaultAnnotationHandlerMapping).
