    ChildListener zkListener = new ChildListener() {

        @Override
        public void childChanged(String path, List<String> children) {
            MappingChangedEvent event = new MappingChangedEvent();
            event.setServiceKey(serviceKey);
            event.setApps(null != children ? new HashSet<>(children) : null);
            listener.onEvent(event);
        }
    };
    List<String> childNodes = zkClient.addChildListener(path, zkListener);

    String servicePath = MAPPING_PATH + Constants.PATH_SEPARATOR + service;
    String content = zkClient.getContent(servicePath);
    if (content != null) {
        Set<String> apps = getAppNames(content);
        MappingChangedEvent event = new MappingChangedEvent(service, apps);
        for (MappingListener listener : listeners) {
            listener.onEvent(event);
        }
