How to customize @RequestParam error 400 response in Spring MVC

Question

Is there a way to customize what gets displayed when a required @RequestParam is not sent to the request handler? I always get HTTP Status 400 with a descriptio

Answer 1

Yes, there is a way you should catch MissingServletRequestParameterException

You can do it in several ways:

1)

   @ExceptionHandler(MissingServletRequestParameterException.class)
      public String handleMyException(Exception  exception) {
       return "yourErrorViewName";
              }  

2)

    org.springframework.web.bind.MissingServletRequestParameterException
    /WEB-INF/pages/myError.jsp
  

Hope it helps.
