我的项目目录结构（在 Eclipse 中）：

MyProjectContainingCSS/
    src/        --> "source directory" on Eclipse's classpath/buildpath
        com.me.myapp
            style.css


MyProjectInheritingCSS/
    src/        --> "source directory" on Eclipse's classpath/buildpath
        com.me.myapp
            StyleImpl.java

我想在类中其他 OSGi 包中的 OSGi 包中包含的 CSS 文件style.css中使用，MyProjectContainingCSSMyProjectContainingCSSStyleImpl.java

就像是：

public class StyleImpl {
    public static void main(String[] args) {
        css = this.getClass().getResource("/com/me/myapp/style.css").toExternalForm();
        scene.getStylesheets().add(css);
    }
}

如何在另一个 OSGi 包的一个 OSGi 包中使用CSS资源文件？

谢谢大家。

要从您自己的包中获取文件，您可以执行以下操作：

Bundle bundle = FrameworkUtil.getBundle(this.getClass());
Enumeration<URL> resources = bundle.getResources("/com/me/myapp/style.css");   
if (resources != null) {
    URL myCSS = resources.nextElement();
}

如果您可以找到其他 OSGi 捆绑对象，您也可以这样做。我会尝试这样的事情：

    Bundle bundle = FrameworkUtil.getBundle(this.getClass());
    Bundle[] bArray = bundle.getBundleContext().getBundles();
    Bundle cssBundle = null;
    for (Bundle b : bArray){
        if(b.getSymbolicName().equals("com.me.myapp")) {
            cssBundle = b;
            break; 
        }
    }
    Enumeration<URL> resources = cssBundle.getResources("/com/me/myapp/style.css");   
    if (resources != null) {
        URL myCSS = resources.nextElement();
    }
