java - 将我的文件放在 netbeans 项目中的何处

Question

我正在 netbeans 中开发一个使用 JSF 的 Web 应用程序。在其中一个托管 bean 中，我必须读取 XML 文件，但我不确定将该文件放在哪里。我尝试将文件放入项目的 root 和 src 文件夹中，但仍然收到 FileNotFoundException。请帮忙。

以下是异常的堆栈跟踪

Answer 1

如果是静态文件，包含在部署的war文件中，只需将其放在src目录中即可。 Netbeans 会将其与 .class 文件一起复制到目标位置。使用加载文件

SomeClassOfTheWebApp.class.getResourceAsStream("/theXmlFile.xml");

Web 应用程序的类加载器将为您加载它。
