我正在从org.apache.felix.scr注释迁移到org.osgi.service.component注释。我有一组从通用抽象类继承的组件。在 felix 的情况下，我可以在超类上使用@Component带有选项的注解componentAbstract=true，然后@Reference在超类中使用注解。我找不到如何将其迁移到 osgi 注释。
是否可以在组件的超类中使用组件注释？如果是这样，那么处理属性和元类型生成的适当方法是什么？
所以，我正在寻找的是这样的东西
/* No component definition should be generated for the parent, as it is
abstract and cannot be instantiated */
@Component(property="parent.property=parentValue")
public abstract class Parent {
@Reference
protected Service aService;
protected activate(Map<String,Object> props) {
System.out.println("I have my parent property: "+props.get("parent.property"));
@Override
public abstract void doSomething();
}
/* For this class, the proper Component definition should be generated, also
including the information coming from the annotations in the parent */
@Component(property="child.property=childValue")
public class Child extends Parent {
@Activate
public activate(Map<String,Object> props) {
super.activate(props);
System.out.println("I have my child property: "+props.get("child.property"));
}
public void doSomething() {
aService.doSomething();
}
}
