Php Symfony框架锁定和.env设置

问题

我需要使用.env设置symfony Framework.yaml参数framework.lock和2+Memcached服务器.但当我try 这样做时，它无法识别2台服务器，但只识别了一台服务器，并且出现了故障.

Symfony Lock Docs:https://symfony.com/doc/current/lock.html

我try 过的(使用代码片段):

Passing via .env

• 我有.env个文件，内容如下:

MEMCACHE_SERVERS='memcached://m1.docker:11211,memcached://m2.docker:11211'

• 有framework.yaml个文件，内容如下:

framework:
    lock: '%env(MEMCACHE_SERVERS)%'

• 让下面的controller method来查看创建的锁对象作为调试

    /**
     * @Route("/example")
     */
    public function exampleAction(LockFactory $lockFactory): JsonResponse
    {
        dd($lockFactory->createLock('testing-lock', 2));
    }

• 它让我跟在后面.其中host个被识别为m1.docker:11211,memcached"个，第二个甚至没有被检测到.

-store: Symfony\Component\Lock\Store\MemcachedStore {#22171 ▼
    -memcached: Memcached {#23004 ▼
      servers: array:1 [▼
        0 => array:3 [▼
          "host" => "m1.docker:11211,memcached"
          "port" => 11211
          "type" => "TCP"
        ]
      ]
      options: {▶}
    }
    -initialTtl: 300
    -useExtendedReturn: null
  }

Passing directly to lock parameter

• 如果我将值直接传递给framework.lock，而不使用.env.它起作用了.

lock: ['memcached://m1.docker:11211','memcached://m2.docker:11211']

• 结果:

  -store: Symfony\Component\Lock\Store\CombinedStore {#22386 ▼
    -stores: array:2 [▼
      0 => Symfony\Component\Lock\Store\MemcachedStore {#23199 ▼
        -memcached: Memcached {#22471 ▼
          servers: array:1 [▼
            0 => array:3 [▼
              "host" => "m1.docker"
              "port" => 11211
              "type" => "TCP"
            ]
          ]
          options: {▶}
        }
        -initialTtl: 300
        -useExtendedReturn: null
      }
      1 => Symfony\Component\Lock\Store\MemcachedStore {#22514 ▼
        -memcached: Memcached {#22625 ▼
          servers: array:1 [▼
            0 => array:3 [▼
              "host" => "m2.docker"
              "port" => 11211
              "type" => "TCP"
            ]
          ]
          options: {▶}
        }
        -initialTtl: 300
        -useExtendedReturn: null
      }
    ]

问题

这个问题.如何使用.env将2+Memcached服务器传递给Framework.lock？
