laravel7.x 该怎么自己捕获ModelNotFoundException 这种异常呢？

User::findOrFail(999999);

if ($exception instanceof \Illuminate\Database\Eloquent\ModelNotFoundException) {
    dd($exception);
}

我的代码不是7.x 不过应该都一样的吧，表面上看不出你代码有啥毛病，以下是源码。 vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php

    /**
     * Prepare exception for rendering.
     *
     * @param  \Exception  $e
     * @return \Exception
     */
    protected function prepareException(Exception $e)
    {
        if ($e instanceof ModelNotFoundException) {
            $e = new NotFoundHttpException($e->getMessage(), $e);
        } elseif ($e instanceof AuthorizationException) {
            $e = new AccessDeniedHttpException($e->getMessage(), $e);
        } elseif ($e instanceof TokenMismatchException) {
            $e = new HttpException(419, $e->getMessage(), $e);
        }

        return $e;
    }
