连接并获取nacos的配置

ConfigService nacosService = nacosConfigManager.getConfigService();
String heartbeatYml = nacosService.getConfig("heartbeat.yaml","DEFAULT_GROUP",1000);

读取数据，将yaml转成map

Map<String,Map<String,String>> obj = toObject(heartbeatYml,Map.class);
currentServerIp = obj.get("server").get("ip");
