我应该把我的资源放在 Scala 的什么地方? [英] Where do I put my resources in Scala?

问题描述

在学习将 Scala 与 JavaFX 结合使用时，我在 ProScalaFX 示例中遇到了以下代码:>

While studying using Scala with JavaFX I have met the following code in a ProScalaFX example:

  val resource = getClass.getResource("AdoptionForm.fxml")
  if (resource == null) {
    throw new IOException("Cannot load resource: AdoptionForm.fxml")
  }

  ...

  val root: jfxs.Parent = jfxf.FXMLLoader.load(resource)

在这种情况下，我应该将实际的AdoptionForm.fxml"内容放在哪里?不幸的是，我不熟悉在 Java 中使用资源.

Where do I put the actual "AdoptionForm.fxml" content in this case? Unfortunately I am neither familiar with using resources in Java.

我使用 SBT 作为构建系统，使用 Idea 作为 IDE.

I use SBT as the building system and Idea as an IDE.

有一个相关问题，它提出了一种方法(将资源文件放在src/main/resources"或src/main/resources/packagename"中)，但它也说它实际上不起作用(不用说我已经尝试过).

There is a related question which suggests a way (putting the resource files in "src/main/resources" or "src/main/resources/packagename"), but it also says it doesn't work actually (needless to say I have tried).

推荐答案

src/main/resources 是在默认 SBT 配置中放置资源的正确位置.

src/main/resources is the correct location for placing resources in a default SBT configuration.

但是，必须注意 getClass.getResource 和 ClassLoader 之间的区别.获取资源.使用 getClass.getResource("AdoptionForm.fxml") 要求文件位于与类的包对应的路径中.

However, one has to be aware of the difference between getClass.getResource and ClassLoader.getResource. Using getClass.getResource("AdoptionForm.fxml") requires the file to be located in a path which corresponds to the package of the class.

例如:如果类位于com.domain.utils，那么资源必须位于src/main/resources/com/domain/utils/AdoptionForm.fxml.

For instance: If the class is located in com.domain.utils then the resource must be located at src/main/resources/com/domain/utils/AdoptionForm.fxml.

为了从包相对位置切换到绝对位置，可以使用 ClassLoader.getResource 或只是在资源字符串前面加上 /.

In order to switch from package-relative locations to absolute locations one can either use ClassLoader.getResource or just prepend the resource string with a /.

示例:getClass.getResource("/AdoptionForm.fxml") 从 src/main/resources/AdoptionForm.fxml
