起初,我尝试在karaf命令行中安装一个包而不是名称,它显示包的绝对路径。过了一段时间,我尝试将包放入deploy,它显示包的确切名称。
我不理解karaf的行为,为什么它在执行正确的命令行安装时没有显示捆绑包名称。而且它根本没有显示任何错误[dependency/compilation/wiredexecption]。有人能告诉我捆绑包中有什么问题吗?您可以改为导入aqte.bnd.annotation 为karaf导入org.apache.felix.scr.annotations 参考下面的代码
@Component(name="ExampleComponentFactoryManager",immediate=true,enabled=true)
public class ExampleComponentFactoryManager
{
private static final Logger LOG = LoggerFactory.getLogger(ExampleComponentFactoryManager.class);
private ComponentFactory factory;
// @Reference(target = "(component.factory=example.factory.provider)",unbind = "unsetFactory")
//private ComponentFactory factory;
private ComponentInstance instance;
private ExampleFactoryService service;
@Activate
public void activate(Map<String, Object> properties) {

service =(ExampleFactoryService)instance.getInstance();
LOG.info("service instance from factory "+service.toString());
}

是否是scr:list
的全部输出?ExampleComponentFactoryManager
丢失是。我只安装了一个捆绑包。ExampleComponentFactoryManager未显示在scr:list中。@Neil,至少我希望SOP会打印出来。但是没有打印任何内容。另外,如果我通过cmd行捆绑包名称安装它,则没有显示的是绝对路径。我不了解Karaf的行为。这是Karaf中的性能问题还是我做错了什么?我认为捆绑包的构造中存在错误,因为ExampleComponentFactoryManager
根本没有出现。但是我只能猜测,因为只有Java源代码已发布。ExampleComponentFactoryManager
丢失是的。我只安装了一个包。ExampleComponentFactoryManager未显示放在scr:list中。@Neil,至少我希望SOP会被打印出来。但是没有什么是优先的
