HandlerExceptionResolver

对于异常我们可以通过注册一个实现HandlerExceptionResolver接口的Bean来解决

@Component
public class CustomerHandlerException implements HandlerExceptionResolver {
    @Override
    public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
        System.err.println(handler.getClass()+" "+request.getRequestURI()+" "+ex.getMessage());
        return null;
    }
}
