你知道如何从我的应用程序中访问 WEB-INF/index 文件夹中的文件吗？我在使用 OpenCMS 来开发我的应用程序，我想要打开 WEB-INF/index 文件夹中位于 Lucene 搜索索引（借助 Lucene IndexReader 类）的 Lucene 搜索索引。Lucene jar 存储在 WEB-INF/lib 文件夹中。
如果您想在WEB-INF文件夹下查找RFS（真实文件系统）中的文件，您可以通过以下方式获取路径：
String filepath = pageContext.getServletContext().getRealPath("/") + "WEB-INF" + java.io.File.separator + "index";
然后使用常见的Java文件方法来读取它。
你打算用那些索引文件做什么？
OpenCms使用Lucene作为其搜索引擎。如果索引文件位于“正确”的文件夹中，则可以在OpenCms中使用Lucene进行其他用途而不会出现任何问题。
