对 private namespace，apollo 已经支持[配置查看权限](https://www.apolloconfig.com/#/zh/usage/apollo-user-guide?id=_61-%e9%85%8d%e7%bd%ae%e6%9f%a5%e7%9c%8b%e6%9d%83%e9%99%90)了。

公共 namespace 使用掩码只能解决页面查看权限的问题，用户通过 config service 的接口依然能访问到配置的值，所以考虑不做掩码的支持

看了下代码，“通过带缓存的Http接口从Apollo读取配置”目前的实现只在缓存失效时会续租客户端实例列表，这个得考虑下如何实现 https://github.com/ctripcorp/apollo/blob/7f35f930feba2ea3e686c2ec87e45dbccf63994e/apollo-configservice/src/main/java/com/ctrip/framework/apollo/configservice/controller/ConfigFileController.java#L174-L191

@furaul java sdk 不存在这个问题，如果你能稳定复现的话，可以新开一个 issue 描述下重现步骤~
