使用ConfigObject使用Java类型安全库获取字符串

对于Java，使用https://github.com/lightbend/config配置：

djobi {
    plugins {
        logger {
            enabled=true
            class="io.djobi.plugins.logging.LoggingPlugin"
        }

        apm {
            enabled=true
            class="io.djobi.plugins.apm_opentracing.APMOpenTracingPlugin"
        }
    }
}

我想遍历插件配置图，如下所示：

final ConfigObject config = this.configuration.getObject("djobi.plugins");

config.forEach((key, subConfig) -> {
    final boolean enabled = this.configuration.getBoolean("djobi.plugins." +  key + ".enabled");

   if (enabled) {
       final String clazz = this.configuration.getString("djobi.plugins." +  key + ".class");

        logger.info("Load plugin " + key);

        ....     
    }

});

如何替换```js this.configuration.getBoolean("FULL_PATH..为subConfig.getBoolean("enabled")？
