条令注释注册登记册装载机更换

要设置基于symphoy注释的路由,我有这一行

AnnotationRegistry::registerLoader([$loader, 'loadClass']);

它工作正常,但已被弃用:

 * @return void
 *
 * @throws \InvalidArgumentException
 *
 * @deprecated this method is deprecated and will be removed in doctrine/annotations 2.0
 *             autoloading should be deferred to the globally registered autoloader by then. For now,
 *             use @example AnnotationRegistry::registerLoader('class_exists')
 */
public static function registerLoader(callable $callable)

从那以后,我不知道该用什么来代替。

谢谢你的建议
