Example 1 with GROUP_KEY

use of org.apache.dubbo.common.constants.CommonConstants.GROUP_KEY in project dubbo by alibaba.

the class NacosRegistry method subscribeEventListener.

private void subscribeEventListener(String serviceName, final URL url, final NotifyListener listener) throws NacosException {
    ConcurrentMap<NotifyListener, EventListener> listeners = nacosListeners.computeIfAbsent(url, k -> new ConcurrentHashMap<>());
    EventListener nacosListener = listeners.computeIfAbsent(listener, k -> {
        EventListener eventListener = event -> {
            if (event instanceof NamingEvent) {
                NamingEvent e = (NamingEvent) event;
                List<Instance> instances = e.getInstances();
                if (isServiceNamesWithCompatibleMode(url)) {
                    // Get all instances with corresponding serviceNames to avoid instance overwrite and but with empty instance mentioned
                    // in https://github.com/apache/dubbo/issues/5885 and https://github.com/apache/dubbo/issues/5899
                    NacosInstanceManageUtil.initOrRefreshServiceInstanceList(serviceName, instances);
                    instances = NacosInstanceManageUtil.getAllCorrespondingServiceInstanceList(serviceName);
                }
                notifySubscriber(url, listener, instances);
            }
        };
        return eventListener;
    });
    namingService.subscribe(serviceName, getUrl().getParameter(GROUP_KEY, Constants.DEFAULT_GROUP), nacosListener);
