使用Wicket在CSS中引用的图像数百张图像 [英] Images referencing in CSS with Wicket for hundreds of images

问题描述

从另一个好的帖子，我们可以使用像这样的单个图像：

As from another nice posts, we can use something like this for 1 single image:

mountSharedResource("/images/logo.gif", new ResourceReference(ImageScope.class, "logo.gif").getSharedResourceKey());

但是如果我们有100张图片需要共享呢？要映射他们1 by 1是没有办法。有没有一些不错的方式如何实现自动安装1目录的所有图像？

But what if we have 100 images needed to be shared ? To map them 1 by 1 is the no way actually. Is there some nice way how to achieve mounting of all images of 1 directory automatically ?

如果没有，我想在写一些支持在一个循环中的mountSharedResource自动对于驻留在具体图像目录中的所有图像。但实际上我不知道这是否正确的方向。

If not, I am thinking about to write some support doing the mountSharedResource in a loop automatically for all images residing in the concrete image directory. But actually I am not sure if it's the right direction.

谢谢。

推荐答案

好吧，我解决了这个问题：

Well, I solved the issue by this:

private void mountResources(Class clazz, String directory) {
    java.net.URL url = clazz.getResource(clazz.getSimpleName() + ".class");

    File[] files = new File(url.getPath()).getParentFile().listFiles();

    for (int i=0; i< files.length; i++) {
        String fileName = files[i].getName();
        if (!fileName.endsWith("class")) {
            mountSharedResource("/" + directory + "/" + fileName, new ResourceReference(clazz, fileName).getSharedResourceKey());
        }
    }
}

    mountResources(ImagesScope.class, "images");
    mountResources(FontsScope.class, "fonts");
    mountResources(JsScope.class, "js");

但令人难以置信的是Wicket不支持内部。我很惊讶。为了安装整个包的书签页面，我们有mount（path，packageName），但是对于资源没有东西（如果我理解的话）。

But it's unbelievable that Wicket doesn't support it somehow internally. I am quite surprised. For mounting bookmarkable pages for the whole package we have mount(path, packageName), but for resources nothing (if I understand it right).
