我在onos升级工作。其中一项升级是我替换了 org.apache.felix.scr。 org.osgi.service.component.annotations。 这是一些捆绑包 onos-api、onos-core-*、onos-app-tunnel-api、onos-app-tunnel 这是我使用bundle:list后卡拉夫指挥官的状态

org.onosproject.net.device.impl 中的DeviceManager.java 和 org.onosproject.net.link.impl 包中的LinkManager.java 位于bundle onos-core-net中，其服务接口org.onosproject.net.device中的DeviceService.java和org.onosproject.net.link中的LinkService.java位于bundle onos-api中
org.onosproject.incubator.net.resource.label.impl 中的LabelResourceManager.java 和 org.onosproject.incubator.net.tunnel.impl 中的 TunnelManager.java 位于捆绑包 onos-app-tunnel 中 org.onosproject.incubator.net.resource.label 中的 LabelResourceService.java 和 org.onosproject.incubator.net.tunnel 中的 TunnelService 位于包 onos-app-tunnel-api 中
@Component(immediate = true, service = {TunnelService.class, TunnelAdminService.class, TunnelProviderRegistry.class})
public class TunnelManager
extends AbstractListenerProviderRegistry<TunnelEvent, TunnelListener,
TunnelProvider, TunnelProviderService>
implements TunnelService, TunnelAdminService, TunnelProviderRegistry {

private static final String TUNNNEL_NULL = "Tunnel cannot be null";
private final Logger log = getLogger(getClass());

@Activate

log.info("EventDeliveryService: {}", EventDeliveryService.class.getProtectionDomain().getCodeSource().getLocation());
eventDispatcher.addSink(TunnelEvent.class, listenerRegistry);
log.info("Started");
}
AbstractListenerProviderRegistry.java 位于 onos-api 包中的 org.onosproject.net.provider 包中 有一个由 TunnelManager 继承的服务引用
@Reference(cardinality = ReferenceCardinality.MANDATORY)
protected EventDeliveryService eventDispatcher;
但是在 karaf.log 中该服务为空 所有捆绑包的版本是

我不知道为什么我无法获得服务引用，尽管它们具有相同的类加载器
有人可以给点建议吗？ 先谢谢你了
这是我尝试过的 当我直接使用@Reference服务时，服务为空，但是当我使用bundleContext时它可以获取服务，这是代码
@Activate
public void activate(ComponentContext context) { BundleContext blContext = context.getBundleContext();
ServiceReference<EventDeliveryService> sr = blContext.getServiceReference(EventDeliveryService.class);if(sr != null) {
eventDispatcher = blContext.getService(sr);
log.info("TunnelManager eventDispatcher from context:{}", eventDispatcher);
}
...
}

它可以从其他bundle中的组件获取服务引用，但无法获取从其他bundle中的基类继承的服务引用。
这是这个网站的解决方案 OSGI @Component 注解不包含扩展现有 OSGI 服务时基类所需的引用
在 pom.xml 中添加一些配置之前 编译后的目录 target/classes/OSGI-INF/org.onosproject.incubator.net.tunnel.impl.TunnelManager.xml
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0" name="org.onosproject.incubator.net.tunnel.impl.TunnelManager" immediate="true" activate="activate" deactivate="deactivate">

</service>
<reference name="store" cardinality="1..1" interface="org.onosproject.incubator.net.tunnel.TunnelStore" field="store"/>

在一些 pom.xml 中添加插件后，我从 TunnelManager.xml 中的基类中获取由 @Reference 注释的引用
