Struts 2 setter 未知字段参数
我的 struts 2 (2.3.1) 应用程序在调试模式下的 url http://localhost/app/check.action?13239 引发了此类异常
2011-12-15 14:45:06,455 DEBUG [CommonsLogger.java:68] : Setting static parameters {}
2011-12-15 14:45:06,456 DEBUG [CommonsLogger.java:68] : Setting params NONE
2011-12-15 14:45:06,456 DEBUG [CommonsLogger.java:68] : Setting params 13239 => [ ]

at ognl.SimpleNode.setValueBody(SimpleNode.java:312)

我希望根据文档默默地忽略它们。解决这个问题的正确方法是什么？
顺便说一句，struts 似乎在寻找值 13239 的 setter 字段，但我猜它不适合以数字开头的属性。
My struts 2 (2.3.1) application at debug mode for url http://localhost/app/check.action?13239 raises such kind of exceptions

I was expecting silently ignoring them according to documentation. What is the correct way to fix this problem?
By the way it seems that struts looking for a setter field for the value 13239 however I guess that it is not suitable for a property which is started by a number.

这或多或少是您个人品味的问题。有时，我们想知道任何时候提交的参数在操作上没有匹配的 getter/setter，并且它是开发我们的应用程序的常见用例，但我们忘记了对于某个操作的 getter/setter，我们想了解任何可能的错误情况。
一种可能的方法是将开发和生产的日志记录级别设置为不同的。在 Struts2 邮件列表上对此进行了很长的讨论，这里是相同

That is more or less a issue of your personal taste.Sometime we wants to know any time a parameter is submitted that doesn't have a matching getter/setter on the action and its a common use case in development our application and we forget a getter/setter on an action, we want to know about any possible error case.
One possible way to is setting the logging level differently from dev to production.There was a long discussion about this on Struts2 mailing list here is the link for same
