Nacos开启鉴权后，客户端如何进行鉴权？

Java SDK鉴权 在构建“Properties”类时,需传入用户名和密码。 比如：

String serverAddr = "{serverAddr}";
Properties properties = new Properties();
properties.put("serverAddr", serverAddr);
// if need username and password to login
    properties.put("username","nacos");
    properties.put("password","nacos");
ConfigService configService = NacosFactory.createConfigService(properties);
