Action class [userAction] not found - action - file:/D:/tomcat-6.0.29/webapps/SS
今天在做SSI框架整合的时候报了一个这样的错误:Actionclass[userAction]notfound-action-file:/D:/tomcat-6.0.29/webapps/SSIBlank/WEB-INF/classes/struts.xml:10:54,找了好久,一直以为我配置的问题或者是缓存的原因,翻来覆去搞了好久也没搞好,最后想想...原来是这样,具体的异常详细信息如下:

面对出现异常的情况一定要冷静的心态,不要看报了一大串异常就觉得无从下手,感到心烦意乱,其实报的异常越多说明你出现的问题越容易找(这是我自己的观点),哈哈...在看异常的时候抓住最后的Causedby,这才是引起异常的最终原因。
下来看我们这个异常:
检查步骤:
1、看看你struts.xml文件中action中对应的class属性的值是否可以在Spring的配置文件中找到对应的id值。
2、如果你确定你的配置没有出现问题,那么一定是你导入包的时候少了包,这时候你检查下你的项目中是否有以下三个jar包,struts2-spring-plugin-2.0.11.1.jar、commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar。
3、导入jar包之后如果还是有同样的错误,这时候你需要清理缓存或者把项目重新部署下,这样应该就可以解决问题了。
