public class ExceptionHandlerFilter extends OncePerRequestFilter {

    @Override
    public void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        try {
            filterChain.doFilter(request, response);
        } catch (RuntimeException e) {

            // custom error response class used across my project
            ErrorResponse errorResponse = new ErrorResponse(e);

            response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
            response.getWriter().write(convertObjectToJson(errorResponse));
    }
}

    public String convertObjectToJson(Object object) throws JsonProcessingException {
        if (object == null) {
            return null;
        }
        ObjectMapper mapper = new ObjectMapper();
        return mapper.writeValueAsString(object);
    }
