Struts debug标签

Struts Debug标签可以在视图的当前位置打印出ValueStack及Stack Context的详细信息。在使用前，我们需要修改struts配置文件把struts.devMode设置成true。

<constant name="struts.devMode" value="true" />

Struts Debug标签打印内容示例

Value Stack部分

	actionMessages	[]	class java.util.LinkedList
	fieldErrors	{}	class java.util.LinkedHashMap
	texts	null	null
