The most important thing is how to reset the include path to add items, as shown below.

最重要的是如何重置include路径来添加配置项，如下所示。

youdao

我希望继续由configuration类来完全维护项阵列，以便在添加其他子类后，那些类将不需要知道如何维护项阵列。

youdao

If you would like to, you can add more items to the list and see how it works.

如果你喜欢，你可以在清单里添加更多的条目来看看它是怎样工作的。
