RouteFunctions를 사용할 때는 PathPattern을 이용할 수 있다.

Rules

? : matches one character
* : matches zero or more characters within a path segment
** : matches zero or more path segments until the end of the path
{spring} : matches a path segment and captures it as a variable named "spring"
{spring:[a-z]+} : matches the regexp [a-z]+ as a path variable named "spring"
{*spring} : matches zero or more path segments until the end of the path and captures it as a variable named "spring"

*path segment : "/"로 구분되는 각각의 덩어리들

(Spring MVC에서 사용하는 것으로 추측되는) AntPathMatcher와 다르게, ** 및 {*name}은 "end of the path" 까지 한 번에 가져옴
