获取ServiceReference的实现

import org.osgi.framework.BundleContext;
import org.osgi.framework.FrameworkUtil;
import org.osgi.framework.ServiceReference;

// 获取ServiceReference的实现示例
public class ServiceReferenceExample {
    public static void main(String[] args) {
        // 获取BundleContext对象
        BundleContext bundleContext = FrameworkUtil.getBundle(ServiceReferenceExample.class).getBundleContext();

        // 获取ServiceReference对象
        ServiceReference<MyServiceInterface> serviceReference = bundleContext.getServiceReference(MyServiceInterface.class);

        // 检查ServiceReference是否为空
        if (serviceReference != null) {
            // 获取服务实例
            MyServiceInterface service = bundleContext.getService(serviceReference);

            // 调用服务方法
            service.doSomething();

            // 释放服务实例
            bundleContext.ungetService(serviceReference);
        }
    }
