Spring RequestMapping: differentiate PathVariable with different types

Is there a way to tell Spring to map request to different method by the type of path variable, if they are in the same place of the uri?
For example,

@RequestMapping("/path/{foo}")  

@RequestMapping("/path/{id}")

if foo is supposed to be string, id is int, is it possible to map correctly instead of looking into the request URI?

According to the spring docs it is possible to use regex for path variables, here's the example from the docs:

@RequestMapping("/spring-web/{symbolicName:[a-z-]+}-{version:\\d\\.\\d\\.\\d}{extension:\\.[a-z]+}")
  public void handle(@PathVariable String version, @PathVariable String extension) {
    // ...
  }
}

(example taken from http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping-patterns )

Judging from that, it should be possible to write something like this for your situation:

@RequestMapping("/path/{foo:[a-z]+}")  

@RequestMapping("/path/{id:[0-9]+}")
