我正在尝试使用org.osgi.service.cm。ConfigurationAdmin来获取我班级的.cfg文件。使用此方法，我可以获取文件中的所有变量，而无需将其列在蓝图中的cm：property-placeholder标记中。
这个类的用法如下：
System.out.println(configurationAdmin);
try {
System.out.println(
configurationAdmin.getConfiguration("com.company.file").getProperties()
);
}
catch (IOException ex) {
Logger.getLogger(MyAppManagerImpl.class.getName()).log(Level.SEVERE, null, ex);
}
我在我的bean中传递了这个服务，如下所述：
然后我收到了这些错误：Caused by: java.lang.Exception: Unable to convert value configurationAdmin to type interface org.osgi.service.cm.ConfigurationAdmin. Type interface org.osgi.service.cm.ConfigurationAdmin is an interface or an abstract class
