1.切换了新的conf加载算法。

    public static Logger logger = LogManager.getLogger(ConfigInitializer.class);

    public static void initialize(Properties properties, Class<?> rootConfigType) throws IllegalAccessException {

                        field.getName()).toLowerCase();

                String value = properties.getProperty(configKey);

                if (value != null) {
