如何允许 spring 引导应用程序使用具有 spring 云依赖性的自定义 jar
How to allow spring boot applications to use custom jar having spring cloud dependency
我有许多 spring 引导微服务,并且我开发了一个新项目,该项目具有 Spring-Vault
作为依赖项。这个新项目(比如 vault-client-spring
)的开发是为了拥有用于设置 Vault 的通用配置并在所有微服务中使用它,我已经在我的组织的私有 Maven 托管存储库中发布了 jar。
我的问题是,当我将此 jar 作为依赖项添加到任何微服务中时,应用程序没有开始抛出以下错误。 Spring-Cloud-Vault
依赖项未导入到我的消费项目中。我还在 bootstrap.yml
文件中添加了以前缀 spring.cloud.vault
开头的必要属性。
这是我的 build.gradle
文件 vault-client-spring
。
