Question

我正在使用zenjava基本原型设计JavaFX程序。一切都可以找到，除非我想使用ImageView小部件添加和Image。

我在src / main / resources下创建了一个名为images的新文件夹，我存储了想在ImageView上显示的图像。

所以，根据这张图片存储在/src/main/resources/images/image.jpg

问题是我打开SceneBuilder并从文件夹C：\ Users \ Toni \ workspace \ MyProject \ src \ main \ resources \ images \ image.jpg中拖放图像，我可以在屏幕上看到图像。我保存fxml文件，然后打开它，fxml文件引用图像如下：

<ImageView fitHeight="200.0" fitWidth="200.0" layoutX="1463.0" layoutY="551.0">
     <image>
        <Image url="@../images/image.jpg" />
     </image>
  </ImageView>

但是，当我编译并运行它时，会出现此错误：

显然，对图像@ .. / images / image.jpg的引用无法正常工作。

所以，我的问题是：

我是否将图像资源放置在原来的位置？如何使用fxml正确引用此图像，以便在运行应用程序时找到图像文件？

谢谢！

假设以下位置：

src/main/java/ - for the Java classes
src/main/resources/fxml/view.fxml
src/main/resources/images/image.png

您应该能够使用以下代码image.png引用view.fxml

<Image url="@/images/image.png" />

使用Javafx和Maven的ImageView的URL路径
