There is no Action mapped for namespace [/user] and action name [user!add] associated with context p

使用struts2.3进行动态方法调用时出现：

There is no Action mapped for namespace [/user] and action name [user!add] associated with context path错误，原因是

（1）DMI可能导致安全问题

（2）DMI与通配符方法功能有重叠，因此该版本Struts2默认关闭DMI，需要在struts.xml中加一句

<constant name="struts.enable.DynamicMethodInvocation" value="true" /> 来打开动态方法调用。动态方法调用官方推荐的做法是，使用通配符的形式。不要使用actionName!methodName的方式。

本人尝试用方法2，问题解决！
