示例1: findDependentContainersRecursively
import org.osgi.framework.ServiceReference; //导入方法依赖的package包/类
/**
* Recursively finds the services registered by the given bundle and the bundles using those services.
* User bundles that have an associated blueprint container are added to containerBundles. In addition,
* if a registered service has an associated config system Module, as determined via the presence of
* certain service properties, the ModuleIdentifier is added to the configModules list.
*
* @param bundle the bundle to traverse
* @param containerBundles the current set of bundles containing blueprint containers
* @param configModules the current set of bundles containing config modules
