java - How to handle requests that includes forward slashes (/)?

Question

I need to handle requests as following:

www.example.com/show/abcd/efg?name=alex&family=moore   (does not work)
www.example.com/show/abcdefg?name=alex&family=moore   (works)
www.example.com/show/abcd-efg?name=alex&family=moore   (works)

It should accept any sort of character from the value that is located between www.example.com/show/ and ?. Please note the value that would be located there would be a single value not name of an action.

For example: /show/abcd/efg and /show/lkikf?name=Jack in which the first request should redirect user to the page abcd/efg (because thats a name) and the second one should redirect user to the page lkikf along with value of parameter name.

I have following controller to handle it but the issue is when I have / in the address the controller is unable to handle it.

@RequestMapping(value = "/{mystring:.*}", method = RequestMethod.GET)
public String handleReqShow(
            @PathVariable String mystring,
            @RequestParam(required = false) String name,
            @RequestParam(required = false) String family, Model model)     {

I used following regex which did not work.

 /^[ A-Za-z0-9_@./#&+-]*$/

Another way I do is:

@RequestMapping(value = "test_handler/**", method = RequestMethod.GET)

...and your test handler can be "/test_hanlder/a/b/c" and you will get the whole value using following mechanism.

requestedUri = (String) 
request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
