Symfony2 Redis Validator，字符串而不是ClassMetadata

Question

我已经从Memcached迁移到了Redis。起初我使用的是PECL Redis 3.1.3，一切正常。更新到3.1.5后，我开始收到错误：

未捕获的PHP异常Symfony \ Component \ Debug \ Exception \ FatalThrowableError：“类型错误：传递给Symfony \ Component \ Validator \ Mapping \ Factory \ LazyLoadingMetadataFactory :: mergeConstraints（）的参数1必须是Symfony \ Component \ Validator \ Mapping \的实例ClassMetadata，给定的字符串，在/ var / www / acme / www上的/var/www/acme/www/vendor/symfony/symfony/src/Symfony/Component/Validator/Mapping/Factory/LazyLoadingMetadataFactory.php中调用/vendor/symfony/symfony/src/Symfony/Component/Validator/Mapping/Factory/LazyLoadingMetadataFactory.php第120行

我看了，并且redis更改日志，并没有找到任何线索，两个版本更新后可能出错。

我的config.yml（只有缓存/ redis的东西）：

        cache: validator.mapping.cache.redis

        cache: serializer.mapping.cache.redis

    redis:

        calls:
            - [ connect, [ '%redis.ip%', '%redis.port%' ]]

    doctrine.cache.redis:
        class: Doctrine\Common\Cache\RedisCache
        calls:
            - [setRedis, ["@redis"]]

    session.handler.redis:
        class: Symfony\Component\HttpFoundation\Session\Storage\Handler\NativeSessionHandler

    serializer.mapping.cache.memcached:
        class: Doctrine\Common\Cache\MemcachedCache


doctrine_cache:
    providers:
        redis_cache:
            redis:

我的symfony版本是2.8.31。有什么建议？

冲洗redis解决了问题..傻

redis-cli flushall
