@PathVariable

该注解主要用于获取路径参数，像url/{id}/{name}这种形式的参数都可以，get获取post请求均可

    @PostMapping("/pathVariable/{id}/{name}")
    @ResponseBody
    public Map<String, String> pathVariable(
            @PathVariable(name = "id") String userId,
            @PathVariable(name = "name") String userName) {
        Map<String, String> map = new HashMap<>();
        map.put("id", userId);
        map.put("name", userName);
        return map;
    }

{
  "name": "5566",
  "id": "2233"
}
