In an example such as the following, what's the difference between a @PathVariable and a @RequestParam?
@RequestMapping(value = "/portfolio/{portfolioIdPath}", method = RequestMethod.GET)
public final String portfolio(HttpServletRequest request, ModelMap model,
@PathVariable long portfolioIdPath, @RequestParam long portfolioIdRequest)
@RequestParam identifies the HTTP GET or POST parameter which is sent by the client(user), And @RequestMapping extracts a segment of URL which varies from request to request:
http://host/?var=1
In the above URL "var" is a requestparam.
http://host/registration/{which}
and above URL's {which} is a request mapping. You could call your service like :
http://host/registration/user
OR like
http://host/registration/firm
In your application you can access the value of {which} (In first case which="user" and in second which="firm".
