Spring MVC, pattern doesn't work properly in case of forward slash symbol in path variable

I have such method in my controller:

@RequestMapping("/action/{actionType:root/testaction}")
public String test( @PathVariable String actionType) {        
}

When I do get request with url localhost/action/root/testaction- this method is not called. But when I change method like:

@RequestMapping("/action/root/{actionType:testaction}")
public String test( @PathVariable String actionType) {        
}

And do the same get request - method works OK. The problem is that I want to include '/root' part into PathVariable string.

Could you clarify what can be wrong in my code?

The problem is that path variables may not contain "/" characters, because that makes the parsing harder.

The Spring @RequestMapping feature partly implements RFC 6570: URI Template. That standard does not allow "/" characters in variable names:

 variable-list =  varspec *( "," varspec )
 varspec       =  varname [ modifier-level4 ]
 varname       =  varchar *( ["."] varchar )
 varchar       =  ALPHA / DIGIT / "_" / pct-encoded

 modifier-level4 =  prefix / explode
 prefix        =  ":" max-length
 max-length    =  %x31-39 0*3DIGIT   ; positive integer < 10000
 explode       =  "*"
