Example 2 with Registry

use of com.alibaba.dubbo.registry.Registry in project dubbo by alibaba.

the class RegistryProtocol method export.

public <T> Exporter<T> export(final Invoker<T> originInvoker) throws RpcException {
    //export invoker
    final ExporterChangeableWrapper<T> exporter = doLocalExport(originInvoker);
    //registry provider
    final Registry registry = getRegistry(originInvoker);
    final URL registedProviderUrl = getRegistedProviderUrl(originInvoker);
    registry.register(registedProviderUrl);
    // 订阅override数据
    // FIXME 提供者订阅时，会影响同一JVM即暴露服务，又引用同一服务的的场景，因为subscribed以服务名为缓存的key，导致订阅信息覆盖。
    final URL overrideSubscribeUrl = getSubscribedOverrideUrl(registedProviderUrl);
    final OverrideListener overrideSubscribeListener = new OverrideListener(overrideSubscribeUrl);
    overrideListeners.put(overrideSubscribeUrl, overrideSubscribeListener);
    registry.subscribe(overrideSubscribeUrl, overrideSubscribeListener);
    //保证每次export都返回一个新的exporter实例
    return new Exporter<T>() {

        public Invoker<T> getInvoker() {
            return exporter.getInvoker();
        }
