@ GetMapping ("user/find/by/ {name} / * *") public String getMapping (@ PathVariable String name, HttpServletRequest request) {String path = request.getAttribute (HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE). ToString (); String path3 = request.getAttribute (HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE). ToString (); String args = new AntPathMatcher (). ExtractPathWithinPattern (path3, path); return name + "/" + args;} Thank you for reading!
