JavaFX 8图像加载（找不到无效的URL或资源） [英] JavaFX 8 Image load (Invalid URL or resource not found)

问题描述

如 docs.oracle about Image class：

as said there docs.oracle about Image class:

// load an image in background, displaying a placeholder while it's loading  
// (assuming there's an ImageView node somewhere displaying this image)  
// The image is located in default package of the classpath
Image image1 = new Image("/flower.png", true);

我在 github ，因此您可以轻松访问代码。

这是我的代码片段：

I shared my simple project at github, so you can easily access code.
and this is piece of my code:

splashScreen = new Image("/gravixsplash.png");
splashScreenBackplate = new ImageView();
splashScreenBackplate.setImage(splashScreen);

instructionLayer = new Image("/gravixinstructions.png");
splashScreenTextArea = new ImageView();
splashScreenTextArea.setImage(instructionLayer);

但这不适合我，我明白了：

But this don't wanna work for me, I get this:

引起：java.lang.IllegalArgumentException：在javafx.scene.image.Image.validateUrl（Image.java:1081）找不到无效的URL或资源

Caused by: java.lang.IllegalArgumentException: Invalid URL or resource not found at javafx.scene.image.Image.validateUrl(Image.java:1081)

at（Image.java:1081）我发现：

at (Image.java:1081) I find this:

if (resource == null) {
    throw new IllegalArgumentException("Invalid URL or resource not found");
}

我假设我的网址（资源）由于某种原因等于null，但它没有帮助我找到解决方案。

I assume that my url(resource) is for some reason equal to null, but it didn't help me find the solution.

（也许某种程度上我需要打开javaFX8，我怀疑intellijIDEA构建javaFX2项目，我在设置中搜索这个，但没有找到任何东西）

(Maybe somehow I need to turn on javaFX8, i suspect that intellijIDEA build javaFX2 project, I was searching for this in settings, but didn't find anything)

推荐答案

项目中的图像不在类路径的根目录中，它们位于：

The images in your project aren't in the root of your class path, they are in:

 /ru/petrsu/javafxGame/

所以代替：

new Image("/gravixsplash.png")

使用：

new Image("/ru/petrsu/javafxGame/gravixsplash.png")

来自

From the Image javadoc:

如果传递的字符串不是有效的URL，而是路径，则在这种情况下在类路径上搜索Image。

If the passed string is not a valid URL, but a path instead, the Image is searched on the classpath in that case.
