How to customize @RequestParam error 400 response in Spring MVC

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 description "The request sent by the client was syntactically incorrect ()." in this case.

Solution

  • 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) 

    <error-page>
    <exception-type>org.springframework.web.bind.MissingServletRequestParameterException</exception-type>
    <location>/WEB-INF/pages/myError.jsp</location>
  </error-page>

    Hope it helps.
