How do i transform subfolders request to params

I'm using Java serve开发者_如何学运维r, and I need the sub-folders in the request to act like parameters.

example:

myhost/p/a/1

and I need the server to "understand" it like that:

myhost/p?a=1

How can I do that?

Thanks, Koby

1: spring 3 mvc @RequestMapping tag can extract path values from uri

 @RequestMapping(value="/owners/{ownerId}", method=RequestMethod.GET)  
 public String findOwner(@PathVariable String ownerId, Model model) {  
   Owner owner = ownerService.findOwner(ownerId);  
      model.addAttribute("owner", owner);  
      return "displayOwner";   
    }

2: use UrlRewiter: http://www.tuckey.org/urlrewrite/. This can extract path parameters using regexp.

<rule>  
    <from>^/image/([A-Za-z0-9-]+).html\??(.*)?$</from>  
    <to>/image.html?imagecode=$1&amp;$2</to>  
 </rule>  

Create a filter -- in that filter getServletPath() then parse the path and forward the request to appropriate controller/servlet

Create a filter at say path /files/* see here,

In this filter add the logic that gets you the whole path after base URL -- i.e. your servlet path see here

You parse this path by splitting using "/" and then pass the array as the parameter to the servlet that want to use this path. see here for forwarding the request
