我正在使用 commons-configuration 1.10，并且希望仅在需要时创建我的配置文件。

目前，我有

        XMLConfiguration config= new XMLConfiguration(file);
        config.setReloadingStrategy(new FileChangedReloadingStrategy());
        config.setAutoSave(true);

但是，当我尝试打电话时

        config.setProperty("portal.0.name", portal.getName());

我明白了

这似乎表明文件无法通过自动保存机制保存。

那么，是不是我做错了什么？

以及如何在仅在需要时创建文件时创建配置（否则将需要一些奇怪的 XML 文件副本）

我使用portal.0.name了我应该使用的地方portal(0).name，这通过……好吧……阅读文档来解决。
