为org.apache.wicket.util.resource启用调试消息

问题

在Wicket中，当找不到html页面时，它将引发“ 为org.apache.wicket.util.resource启用调试消息以获取所有尝试过的文件名的列表 ”。 想知道如何为Wicket资源启用调试消息？

Root cause:
org.apache.wicket.markup.MarkupNotFoundException: 
Markup of type 'html' for component 'com.mkyong.hello.Hello' not found. 

Enable debug messages for org.apache.wicket.util.resource to get a list of all filenames tried.: 
[Page class = com.mkyong.hello.Hello, id = 0, version = 0]
at org.apache.wicket.markup.MarkupCache.getMarkupStream(MarkupCache.java:227)
...

解

我也不知道如何在“ org.apache.wicket.util.resource ”上启用调试，Wicket错误消息应该更清晰！

或者，您可以启用调试模式下的日志记录，并跟踪Wicket如何通过日志文件查找资源。 例如， 将log4j与Wicket集成 。

log4j输出样本…
