列表視圖中的Wicket IPackageResourceGuard圖像

我無法將圖像添加到位於my/webapp/images /目錄中的我的列表視圖中。列表視圖中的Wicket IPackageResourceGuard圖像

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"))); 
     } 
    };

我看網上說檢票（版本號）增加了一個IPackageResourceGuard所以不需要的文件不被訪問，所以我說這個我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"); 
    } 

}

這是爲了允許使用.png，但我仍然得到異常！

似乎圖像構造函數是錯誤的。看圖像的例子。 –

在你的父母，你有：<wicket:child></wicket:child>

在你的孩子：<wicket:extend></wicket:extend>

,,需要在你的孩子改變，你必須把這個： <wicket:extend xmlns="http://www.w3.org/1999/xhtml" lang="en" xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd">

試試吧。
