Controller: @PutMapping("/d3") public String d3(@RequestParam("id") String id, @RequestParam("k") int k){ return id+","+k; }

  1. @EnableWebMvc and "PUT" "application/x-www-form-urlencoded" data in body,it's will MissingServletRequestParameterException.
  2. But "POST" "application/x-www-form-urlencoded" data in body everything is ok.
  3. Remove @EnableWebMvc "PUT" "application/x-www-form-urlencoded" data in body everything is ok.
