Configuration.getKeys介绍

[英]Get the list of the keys contained in the configuration. The returned iterator can be used to obtain all defined keys. Note that the exact behavior of the iterator's remove() method is specific to a concrete implementation. It may remove the corresponding property from the configuration, but this is not guaranteed. In any case it is no replacement for calling #clearProperty(String) for this property. So it is highly recommended to avoid using the iterator's remove()method.
[中]获取配置中包含的密钥列表。返回的迭代器可用于获取所有定义的键。请注意，迭代器的remove（）方法的确切行为是特定于具体实现的。它可以从配置中删除相应的属性，但这不能保证。在任何情况下，它都不能替代为此属性调用#clearProperty（String）。因此，强烈建议避免使用迭代器的remove（）方法。
