说明：action已经被执行，但该返回result时就出现这个错误！
Struts2的配置中：Could not find action or result 问题的解决方法
[img]http://img.chinawin.net/it/343/59010/1.jpg[/img]
以上是我的工程目录结构，我把struts.xml没有放到src下，而是根据自己的习惯放到新目录：WEB-INF/conf/下了。这时候需要在web.xml中进行必要的配置，配置情况如下：
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
config
struts-default.xml,struts-plugin.xml,/WEB-INF/conf/struts.xml
Struts.xml内容如下：
index.jsp
这时候在IE地址栏中访问：http://localhost:808/test/ddd
时会报错，错误信息如下：

解决办法如下：
只要对web.xml稍做一点改动就行，改成如下：
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
config
struts-default.xml,struts-plugin.xml,../conf/struts.xml
这样就一切OK了。
最讨厌struts2的异常机制，名义上是封装统一处理，但是也将异常搞得难以调试。
可以说，在请求中的任何一个地方抛出异常都是报的上面的错误。
因此，你贴出的日志几乎没有什么价值。
唯一能说的是，建议你分步调试。
如
1.进了Action没有。
2.将jsp页面清空，进入jsp页面了没
3.是否是jsp页面中某个表达式或标签错误。
个人感觉第三种情况发生机率频繁点。
[quote]我的是先进入jsp页面再进入action，所以action是进入了的，再返回result的字符串时就出现上面的错误，返回的页面是没有什么数据的！ [/quote]
无论有没有数据，你能保证你进入了jsp没有啊，
都说过了，是分步调试，缩小错误发生的范围。
你直接给我们日志，是无意义的。
除非非常明显的错误，不然，没有人能帮你定位到错误发生的地方。。
确实应该debug 下 到哪步出错！具体位置！
这样太笼统了！ 关，注中。。。
/loginFail.jsp
是否有呢？
页面也debug 下 参数什么是否传了呢？
[quote]
我是运行到action里的方法，执行了操作后，即execute（）方法，里面有些函数调用也执行了，该是返回页面时才报的上面的错！ [/quote]
为什么你会用这么不确定的回答啊。
如果在action的最后一步return之前还正确，并且return的是一个正确的字符串，那么就就该进一步呀。
找到return的字符串对应的jsp页面，写个hello world，看能不能返回正确的值。
[quote]我将action改为了
[/quote]
没加spring？ 单独用的 struts2
return了一个错误的字符串?
[quote]2、我将action改为了
[/quote]
加了spring 还这么干！
说没你的 配置有问题
可能是struts-convention-plugin改变了返回的默认路径
添加 到struts.xml
struts.convention.result.path可以设置错误了
哦，这个插件好像有些麻烦，以前没用过。
查了下资料，还有些其它如命名空间之类的说法，看来有些复杂。
