Java struts 2中的logMissingProperties

当jsp向和操作发送响应时，OGNL尝试将请求参数与操作属性匹配。如果找不到任何属性，它将在堆栈中引发并执行以下选项跟踪：

您知道，即使在开发过程中，这种跟踪也毫无帮助。一条简单的信息似乎就足够了

我知道我可以通过更改一些日志级别来禁用它

我发现同样的问题似乎没有得到回答

最近我发现了一些东西，听起来我可以通过低于常量来禁用这种行为

<constant name="struts.ognl.logMissingProperties" value="false" /> 

这不管用！

任何注释

关闭struts2

devMode

和OGNL异常/警告都将被禁止

在struts.xml文件中定义以下内容

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

devMode功能非常有用，在devMode期间，此堆栈跟踪是无用的<代码>我知道我可以通过更改一些日志级别来禁用此功能。-这是唯一可以做到的。
