Throwing HTTP Status code exception from HandlerInterceptor

Question

I am trying to create a HandlerIntecerptor whose pre-handle has the code structure as follows

    public boolean preHandle(HttpServletRequest req, HttpServletResponse res, Object handler) throws Exception {

    boolean check = //do something
    if(!check)
    {
        throw new HttpStatusCodeException(HttpStatus.TOO_MANY_REQUESTS); //This line gives cannot be instantiated error.
    }
    return check;
}

but it says class cannot be instantiated. Is there a way to throw an http code exception from inside the preHandle?

`httpServletResponse.setStatus(HttpStatus.TOO_MANY_REQUESTS.value()); return false;` could you please try ? — Ataur Rahman Munna, Aug 28 '18 at 07:23

The class HttpStatusCodeException is Abstract and can not be instanciated.

Form the Javadoc:

public abstract class HttpStatusCodeException

Use HttpClientErrorException or HttpServerErrorException

HttpStatusCodeException is an abstract class which means that you cannot throw it without creating an anonymous inner class and overriding the abstract method first.
