Spring MVC RequestMapping PathVariable in the first place - spring

Question

I would like to set for each user's own profile link.
Like this:
#RequestMapping(value = "/{userlogin}", method = RequestMethod.GET)
public String page(#PathVariable("userlogin") String userlogin, ModelMap model) {
System.out.println(userlogin);
return "user";
}
But static pages get this expression too..
Like this:
#RequestMapping(value = "/hello", method = RequestMethod.GET)
public String hello() {
System.out.println("hello mapping");
return "hello";
}
That is when I request GET request "hello" that calls both controllers.
I would like to do that, user controller calls only if other methods not called.
Console, when I calls localhost:8080/123:
123
Console, when I calls localhost:8080/hello:
hello
hello mapping
or
hello mapping
hello
I want to get only
hello mapping
when calls localhost:8080/hello
Who knows how it can be implemented?

Spring MVC can use URI Template Patterns with Regular Expressions. Provided :
userlogin only contain digits
others URL immediately under root contains at least one non digit character
you can use that in your #RequestMapping :
#RequestMapping(value = "/{userlogin:\\d+}", method = RequestMethod.GET)
public String page(#PathVariable("userlogin") String userlogin, ModelMap model) {
//...
}
If the separation between userlogin and other URL is different from what I imagined, it can be easy to adapt.
