Question

我是Wicket的新手，正在开展现有项目。如何在UI上看到Wicket的堆栈跟踪？目前我看到以下内容：

内部错误
返回主页

我在log4j.xml中设置了以下内容，但在日志中看不到任何堆栈跟踪：

<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);
    }
}

 <param-name>configuration</param-name>
 <param-value>development</param-value>
 </context-param>

将web.xml更新为开发而非部署

此外，调试输出的详细信息由wicket的“配置”运行时确定，请参阅http://clipmarks.com/clipmark/B00CE497-A646-4CB6-B85D-F68332903C5A/的简短说明
