我已经创建了基于Maven的项目,我想通过使用下面的代码来启动OSGi容器(Felix),但每次都给我以下异常 -
Exception in thread "main" java.util.NoSuchElementException
at java.util.ServiceLoader$ServiceIterator.next(ServiceLoader.java:187)
at com.ebay.personalization.osgi.test.osgitest.App.main(App.java:28)
以下是我的代码:
import org.apache.commons.io.FileUtils;
import org.apache.felix.framework.FrameworkFactory;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleContext;
import org.osgi.framework.BundleException;
import org.osgi.framework.ServiceReference;
import org.osgi.framework.launch.Framework;
public class App {
public static void main(String[] args) throws BundleException, IOException {
FileUtils.deleteDirectory(new File("felix-cache"));
FrameworkFactory frameworkFactory = ServiceLoader.load(FrameworkFactory.class).iterator().next();
Framework framework = frameworkFactory.newFramework(new HashMap<String, String>());
framework.start();
BundleContext context = framework.getBundleContext();
List<Bundle> installedBundles = new LinkedList<Bundle>();
installedBundles.add(context.installBundle("C:\\Store\\TestingModel-1.0.0.jar"));
for (Bundle bundle : installedBundles) {
bundle.start();
}
ServiceReference reference = context.getServiceReference(ITestService.class.getName());
ITestService service = (ITestService) context.getService(reference);
service.speak();
}
}
一旦我运行上面的代码,我总是得到上面提到的异常 -
下面是我的pom.xml文件:

有谁能告诉我,我在这里做错了什么?我知道ServiceLoader在类路径中搜索FrameworkFactory接口,如果它无法找到,那么它将抛出异常。但在我的情况下,我已经依赖于felix框架,所以它应该在我的类路径中。对吧?那我做错了什么?
