描述bug

多个应用引用同一个apollo配置时，不同应用间的配置差异我们采用了环境变量去覆盖apollo配置。但使用过程中，发现key中带"-"的配置使用此方式覆盖失败。

复现

通过如下步骤可以复现：

期望
配置应该被覆盖为true

根据我在Apollo仓库中的查找，我没有找到关于环境变量覆盖配置时，键中包含"-"字符会失败的相关信息。Apollo配置管理系统通过在属性文件中使用占位符来处理环境变量。这些占位符由${<variable_name>}语法表示。

例如，在提供的上下文中，dev.meta=${dev_meta}意味着在运行时，dev.meta属性将被dev_meta环境变量的值替换。

这允许Apollo根据其运行的环境动态调整其配置，无需更改代码或重新编译应用程序。你可以在这个链接中查看相关的代码：apollo-portal/src/main/resources/apollo-env.properties

关于你提到的问题，我建议你提供更多的信息，例如你的环境变量和配置的具体情况，以及你在尝试覆盖配置时遇到的具体错误。这将有助于我更好地理解和解答你的问题。

不是同一种情况，还请人工帮忙看一下，感谢~

@nobodyiam, I could use your expertise on this one.

经过多次测试，不是带"-"的key覆盖失败，而是key-value左右值不相等才会覆盖失败，改成如下图格式后，环境变量是可以进行覆盖的（ps：也就是说想要用环境变量去覆盖apollo的配置，就必须保持key-value左右值相等。。）。

@ZeroSong211 这个是 spring 自身的配置规则，简而言之 test.param.enable-test 等同于环境变量 TEST_PARAM_ENABLE_TEST，两个都是 KEY，不是 value。

[ZeroSong211]

TEST_PARAM_ENABLE_TEST打错了吧。。应该是TEST_PARAM_ENABLE-TEST
