Obtaining @PathVariable in an interceptor

[tazzer]

Hi

We're using an interceptor to some of our controllers to check that the user is logged on.

The controller method has a path variable in the signature....

@RequestMapping(method=RequestMethod.GET)
public String getVehicleForListing(@PathVariable String listingId, Model model) {
.....
}

Is there an easy way to extract that @PathVariable in the interceptor method...

public boolean preHandle(HttpServletRequest request,  HttpServletResponse response, Object handler)
	    throws Exception {
......
}

I wondered whether there is any spring component that I could inject into the interceptor to extract that path variable.

Thanks for all help

Nope... The pathvariable is available after the prehandle method. It is produced by the RequestMappingHandlerAdapter and that is only called after succesful invocation of the preHandle methods of all interceptors.

Also why would you need to attribute if it is a pathvariable it is part of your url, so storing the url and redirecting after successful login should be enough. Also I suggest using Spring Security instead of implementing your own solutions...

Map pathVariables = (Map) request.getAttribute(HandlerMapping.URI_TEMPLATE_V ARIABLES_ATTRIBUTE);
