Spring MVC Url pattern

Question

I was wondering if I can customize my url into controller to accept null values @RequestMapping( value = "foo/{y}/{x}", method = RequestMethod.GET) public ModelAndView doSmth(@PathVariable(value = "x") String x, @PathVariable(value = "y") String y) { } Here in my case , X , Y can be empty string . How could I manage smth like that to let this method on the controller to handle this url ?

If you want to support optional values, then path variables aren't well suited. Request parameters (using @RequestParam) are a better idea, since they easily support optional values using the required attribute. If you really want to support optional path variables, then you need to overload your mappings, i.e. @RequestMapping(value = "foo/{y}/{x}") public ModelAndView doSmth(@PathVariable(value = "x") String x, @PathVariable(value = "y") String y) @RequestMapping(value = "foo/{y}") public ModelAndView doSmth(@PathVariable(value = "y") String y) @RequestMapping(value = "foo") public ModelAndView doSmth()
