【问题描述】：
我无法将图像添加到位于 /webapp/images/ 目录中的列表视图。
ListView<Games> gamesList = new ListView<Games>("gamesList", games) {
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem<Games> item) {
Games game = item.getModel().getObject();
item.add(new Image("champImage", "hello").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("enemyChampImage", "world").add(new AttributeModifier("src", "dorans.png")));
item.add(new Label("champName", game.getChampName()));
item.add(new Label("enemyChampName", game.getEnemyChampName()));
item.add(new Label("goldSpent", game.getGoldSpent()));
item.add(new Image("item0", "name1").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item1", "name2").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item2", "name3").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item3", "name4").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item4", "name5").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item5", "name6").add(new AttributeModifier("src", "dorans.png")));
item.add(new Image("item6", "name7").add(new AttributeModifier("src", "dorans.png")));
}
};
我在网上看到 Wicket (version#) 添加了一个 IPackageResourceGuard，因此不需要的文件不会被访问，所以我将它添加到我的 WicketApplication.java。
@Override
public void init()
{
super.init();
// add your configuration here
IPackageResourceGuard packageResourceGuard = this.getResourceSettings().getPackageResourceGuard();
if (packageResourceGuard instanceof SecurePackageResourceGuard) {
SecurePackageResourceGuard guard = (SecurePackageResourceGuard) packageResourceGuard;
guard.addPattern("+*.png");
}
}
这是为了允许使用 .pngs，但我仍然遇到异常！

好像Image构造函数有问题。查看图片示例。
