caching - Mule 4 - 使用 Redis 连接器作为自定义对象存储 "Connection is no longer valid"

Question

我正在尝试使用 Redis 作为 Mule 4 项目的对象存储的后端。我已按照说明进行操作 here ，但是在项目启动时我不断收到错误消息:

Caused by: reactor.core.Exceptions$ReactiveException: org.mule.runtime.api.exception.DefaultMuleException: Obtained invalid connection from ObjectStore config 'ObjectStore_Config'. Error Type: UNKNOWN. Message: Connection is no longer valid

这是我的配置的截断 View :

<mule xmlns:redis="http://www.mulesoft.org/schema/mule/redis"
    xmlns:os="http://www.mulesoft.org/schema/mule/os"

我在本地机器上从 docker 运行 Redis:

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
126faa8c33a7        redis:3.2.12        "docker-entrypoint.s…"   5 days ago          Up 5 days           0.0.0.0:6379->6379/tcp   redis

我已经在一个单独的项目中验证了我可以使用 redis 连接器连接到这个实例并获取/设置数据。

为什么此连接不再适用于 ObjectStore 配置？

我将我的项目与 mule 支持提供的示例项目进行了比较 here并发现我需要添加 <redis:redis-config>元素，以及拆分我的 host redis:nonclustered-connection 上的属性嵌套在 os:config 内两者都是 host和 port :

<os:config name="ObjectStore_Config">
  <redis:nonclustered-connection host="localhost" port="6379"/>
</os:config>

<redis:redis-config name="Redis_Redis" doc:name="Redis Redis" >
  <redis:nonclustered-connection />
</redis:redis-config>
