symfony - 如何在 Symfony5 中为 Doctrine 配置 apcu

Question

在 Symfony4 中，我使用以下配置来进行 Doctrine apcu 缓存:

doctrine:
    orm:
        auto_mapping: true
        auto_generate_proxy_classes: false
        metadata_cache_driver: apcu
        query_cache_driver: apcu
        result_cache_driver: apcu

升级到 Symfony5 后，出现错误:

Unknown cache of type "apc" configured for cache "metadata_cache" in entity manager "default".

将其更改为以下配置时，它可以工作:

doctrine:
    orm:
        auto_mapping: true
        auto_generate_proxy_classes: false
        metadata_cache_driver:
            type: pool
            pool: doctrine.system_cache_pool
        query_cache_driver:
            type: pool
            pool: doctrine.system_cache_pool
        result_cache_driver:
            type: pool
            pool: doctrine.result_cache_pool

但是我现在使用什么样的缓存？我怎样才能将它切换到apcu？

我在 Symfony 4.4.5 中遇到了同样的问题

您应该首先安装 Symfony Cache Component .然后，您应该按如下方式配置缓存池、服务和 Doctrine 缓存:

doctrine:
    orm:
        auto_generate_proxy_classes: false
        metadata_cache_driver:
            type: service
            id: doctrine.system_cache_provider
        query_cache_driver:
            type: service
            id: doctrine.system_cache_provider
        result_cache_driver:
            type: service
            id: doctrine.result_cache_provider

services:
    doctrine.result_cache_provider:
        class: Symfony\Component\Cache\DoctrineProvider
        public: false
        arguments:
            - '@doctrine.result_cache_pool'
    doctrine.system_cache_provider:
        class: Symfony\Component\Cache\DoctrineProvider
        public: false
        arguments:
            - '@doctrine.system_cache_pool'

framework:
    cache:
        pools:
            doctrine.result_cache_pool:
                adapter: cache.adapter.apcu
            doctrine.system_cache_pool:
                adapter: cache.adapter.apcu
