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.
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.
