This * should be actively added when registering with the registry. There seems to be no usage found in the feature announcement of version 3.1.0, please advise provider的配置文件中并没有主动设置 rest 协议，这个*应该是注册到注册中心时主动添加的。3.1.0版本的feature公告中好像没有发现用法，请指教 -- This is an automated message from the Apache Git Service.
