spring-cloud-config匹配资源，但不将配置返回给客户端。

Question

Spring (Version2.2.0.RELEASE)似乎匹配批准的资源(在日志中，相关文档是从yml加载的)，但不将此配置的内容返回给客户端。我向Postman注入了一个类似的查询，响应有效负载如下：

来自配置服务器的响应有效负载

{
    "name": "core-application",
    "profiles": [
        "user,local,dev,quick"
    ],
    "label": null,
    "version": null,
    "state": null,
    "propertySources": []
}

配置服务器的相关日志(带有--debug选项) :

知道为什么配置的内容不返回给客户端吗？

Answer 1

我终于找到了原因：

配置服务器应用程序中的LOCAL_GIT_REPOSITORY环境变量必须用“正则”斜杠(“/”)定义，而我使用的是带有反斜杠的windows路径(“\”)。

棘手的部分是服务器部分处理windows路径(如调试日志所示，.yml文件被找到并正确加载)。故障几乎发生在进程的末尾，在clean()类的NativeEnvironmentRepository函数中:在向配置客户端发送响应之前，该函数比较yml文件的位置以更正“模式路径”，这是windows路径未被正确处理的地方。(位置是计算的，混合了两种斜杠：C:\Users\Edouard\myconfig/myapp/)

也许弹簧云配置抛出一个正确的错误，或者正确地处理它是个好主意。
