spring-cloud 中 config client 调用 /refresh 返回 401

学习 spring-cloud 的时候 碰到了一个问题

大家有时间 来围观下啊.

spring-cloud 中 config client 调用 /refresh 返回 401

我本来是 想测试 下
在 github 修改配置文件的 value
然后 配置调用客户端 希望看到的是 取到的是最新的 配置参数值

前提 必须是 POST 请求 调用 一下 /refresh

可是 怎么返回下面这个东东 啊 😅

{"timestamp":1499418081361,"status":401,"error":"Unauthorized","message":"Full authentication is required to access this resource.","path":"/refresh"}

以下是 pom 配置 还有 spring-cloud 相关依赖的 版本.
大家是否有遇到这个问题呢 ?
