我已在log4j.xml以下，但沒有看到任何堆棧跟蹤日誌中的任一：

<logger name="org.apache.wicket"> 
    <level value="DEBUG"/> 
</logger> 

Answer 1

public class MyApplication extends WebApplication { 
    @Override 
    protected void init() { 
     /* ... */ 

     // Tells wicket to use a helpful 'debug' exception page with a snapshot of the 
     // component model, and the exception stack trace. 
     // Other settings are available to show pages that say there has been an internal error 
     // (a production-friendly page) 
     // In addition, more advanced usage allows you to override this behavior completely. 

     getSettings().setUnexpectedExceptionDisplay(ApplicationSettings.SHOW_EXCEPTION_PAGE); 
    } 
}

另外，調試輸出的細節由檢票的「配置」運行時間決定，請參見http://clipmarks.com/clipmark/B00CE497-A646-4CB6-B85D-F68332903C5A/的簡要說明

更新web.xml中發展，而不是部署
