CacheFilter 怎么仅提供者生效

测试版本 version 2.7.8
当在接口上配置了cache=expiring的缓存配置后,消费者和提供者对该配置都生效了
怎么配置才能仅提供者生效?

Start by reproducing the behavior described for Dubbo version 2.7.8: configure cache=expiring on an interface and observe its effect on both the consumer and provider. Inspect the relevant cache configuration and filtering behavior, then verify whether a supported configuration can limit it to the provider; done means the behavior or configuration is clearly established.
