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

How I solved my problem:

@ResponseBody
@ExceptionHandler(MissingServletRequestParameterException.class)
public Object missingParamterHandler(Exception exception) {
    // exception handle while specified arguments are not available requested service only. it handle when request is as api json service       
    return  new HashMap() {{ put("result", "failed"); put("type", "required_parameter_missing");}};
}
