檢票：ModalWindow和ClassNotFound的：CompressedResourceReference

Question

每次我試圖實現一個modalwindow我得到：

拋出java.lang.ClassNotFoundException：org.apache.wicket.request.resource.CompressedResourceReference

我的圖書館中都沒有這個元素。我的依賴是：

<dependency> 
     <groupId>org.apache.wicket</groupId> 
     <artifactId>wicket-core</artifactId> 
     <version>1.5.3</version> 
    </dependency> 

    <!-- DatePicker --> 
    <dependency> 
     <groupId>org.apache.wicket</groupId> 
     <artifactId>wicket-datetime</artifactId> 
     <version>1.5.2</version> 
    </dependency> 


<dependency> 
<groupId>org.apache.wicket</groupId> 
<artifactId>wicket-extensions</artifactId> 
<version>1.5.3</version> 
</dependency> 

€這就是我如何實現我的modalwindow：

import org.apache.wicket.ajax.AbstractAjaxTimerBehavior; 
import org.apache.wicket.ajax.AjaxRequestTarget; 
import org.apache.wicket.ajax.markup.html.AjaxLink; 
import org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow; 
import org.apache.wicket.markup.html.WebPage; 
import org.apache.wicket.util.time.Duration; 



public class ModalPanel1 extends WebPage 
{ 
public ModalPanel1(String id) 
{ 
final ModalWindow modalWindow = new ModalWindow("modal"); 

modalWindow.setTitle("Popup"); 
modalWindow.setInitialWidth(400); 
modalWindow.setInitialHeight(400); 
modalWindow.setResizable(true); 
modalWindow.setContent(new AbstractModalClosePanel(modalWindow) 
{ 
    public void onClick(AjaxRequestTarget target) 
    { 
    modalWindow.close(target); 
    } 
}); 
add(modalWindow); 

add(new AjaxLink<Void>("open") 
{ 
    @Override 
    public void onClick(AjaxRequestTarget target) 
    { 
    modalWindow.show(target); 
    } 
}); 

add(new AbstractAjaxTimerBehavior(Duration.seconds(2)) 
{ 
    @Override 
    protected void onTimer(AjaxRequestTarget target) 
    { 
    modalWindow.show(target); 
    stop(); 
    } 
}); 
} 
} 

和

import org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow; 
import org.apache.wicket.markup.html.panel.Panel; 


public abstract class AbstractModalClosePanel extends Panel 
{ 
    public AbstractModalClosePanel(ModalWindow modalWindow) 
    { 
super(modalWindow.getContentId()); 



} 

有沒有舊的進口。

Answer 1

CompressedResourceReference在檢票1.5與其他COMPRE沿着下降ssion的東西。

如果您在自己的代碼中有此參考，則應該使用正常的ResourceReference或其他非壓縮版本。

在早期版本中，它ModalWindow使用，但它不是至少在1.5.3，所以

<dependency> 
    <groupId>org.apache.wicket</groupId> 
    <artifactId>wicket-extensions</artifactId> 
    <version>1.5.3</version> 
</dependency> 

應該有工作。

我會再試一次，並確保你有一個乾淨的更新，所以沒有參考舊的ModalWindow代碼掛起。

在發佈候選版本中可能還有參考文獻，因爲我認爲它在某些版本候選版本中仍然以核心爲核心。

您可能還需要查看更多堆棧跟蹤以縮小對此類的引用範圍。
