可以通过转发实现

@RestController
public class DefaultController {

@RequestMapping("/{controller}/{action}/{apiVersion}/{userId}/{clientName}")
public void index(@PathVariable String controller,
@PathVariable String action,
@PathVariable String apiVersion,
@PathVariable String userId,
@PathVariable String clientName, HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.setAttribute("apiVersion", apiVersion);
request.setAttribute("userId", userId);
request.setAttribute("clientName", clientName);

request.getRequestDispatcher(String.format("/%s/%s", controller, action)).forward(request, response);
}

@RequestMapping("/home/index")
public String hello(HttpServletRequest request) {
System.out.println(request.getAttribute("apiVersion"));
System.out.println(request.getAttribute("userId"));
System.out.println(request.getAttribute("clientName"));
return "Hello World!";
}

}
