Karaf OSGi 配置抛出 ResolutionException：无法解析 root：缺少要求 [root] osgi.identity；
Karaf OSGi config throws ResolutionException: Unable to resolve root: missing requirement [root] osgi.identity;
我正在创建一个 Spring 引导应用程序，它将 运行 在 Karaf 上。我试图在 Karaf 中公开项目配置属性，以便能够使用 config:property-set 更改属性而无需重新部署应用程序。
所以我已经设法配置我的 karaf 功能以将属性公开给 Karaf 但我正在尝试创建一个 OSGi 组件以便能够在 属性 更改为 config:property 时获取更新-set.
我在尝试安装 .kar 文件时遇到的错误如下：

这是我的github repo。我正在使用 java 8 和 Maven 3.6，org.osgi.core 5.0.0，Karaf 4.1.3
有什么办法可以解决这个问题吗？使用@Component 和@Modified 从 Karaf 获取 属性 修改更新的正确方法是什么？
提前致谢！
该错误消息表示您缺少满足您的捆绑包要求之一的捆绑包。
您在这条长错误消息的末尾找到了缺少的要求：
(&(osgi.extender=osgi.component)(version>=1.3.0)(!(version>=2.0.0)))
这意味着您缺少 osgi.component 型号的扩展器。
那么那里发生了什么？您在 类 中使用声明性服务注释。 Maven bundle 插件读取它们并为声明性服务创建 xml 以及上面扩展程序的要求。
所以这个要求可以帮助您在安装包时不会错过声明式服务运行时。
对于 karaf，解决方案是安装提供运行时的功能：
feature:install scr
您遇到上述错误是因为未安装依赖包或安装的包的版本不在范围内，
您可以在 karaf 终端中通过以下命令检查包是否已安装以及安装的版本是什么：
la -l|grep "#bundle name"
其中包名称是您遇到错误的包，
有时可能只缺少一个包，但也有可能没有安装该功能，该功能只不过是一组包，
要检查该功能是否已安装，请使用以下命令：
feature:list|grep "#feature name"
在这里，您可以安装该功能，它应该可以解决问题
feature:install scr
