Question

当jsp发送响应并执行操作时，OGNL会尝试将请求参数与操作属性进行匹配。如果它找不到任何属性，它将在栈中引发和删除跟踪，如下所示：

您知道即使在开发过程中，此跟踪也无济于事。一条简单的信息似乎就够了！

我知道我可以通过更改一些日志级别来禁用它。

我在getting Developer Notifications about OGNL exceptions after upgrading to struts 2.3.14.2 from 2.3.1.2找到了同样的问题，似乎没有得到解答！

最近我发现了一些SOUNDS我可以通过低于常数

来禁用此行为

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

哪个没用！任何评论

Answer 1

关闭struts2 devMode和OGNL例外/警告，将被压制。

在struts.xml文件中定义以下内容

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

struts 2中的logMissingProperties
