在命名空间中没有定义login的返回页面<package name="struts" extends="struts-default" namespace="/struts">
<action name="/login.action" class="struts.RegisterAction">
<result name="login">success.jsp</result>
<result name="error">error.jsp</result>
<result name="input">register.jsp</result>
</action>
<action name="/login.action" class="struts.RegisterAction">
<result name="login">success.jsp</result>
<result name="error">error.jsp</result>
<result name="input">register.jsp</result>
</action>
警告: Could not find action or result
There is no Action mapped for namespace / and action name login. - [unknown location]
为什么要用/login.action呢，直接/login就行了。
会不会和我放struts的位置有关
改成name=“login” 就行 还有一点就是把struts.xml方在项目的src下(classpath) \
第四点 <param-value>struts-default.xml,struts-plugin.xml,../struts-configs/struts.xml </param-value> 这里struts-default.xml struts-plugin.xml不要在这里加载 因为你自定义的struts.xml已经继承了struts-default.xml就会去加载struts-core.jar中的struts-default.xml
struts-plugin.xml也会在tomcat启动的时候加载
但是struts-plugin.xml不知道是dispather的时候加载还是在加载struts-default.xml的时候就加载了
在/struts的路径下没有找到，名字叫login的action
<package name="struts" extends="struts-default" namespace="/struts">
namespace="/struts" 这样配置的package只能接受/struts路径下的请求第一种解决方案：
<package name="struts" extends="struts-default" namespace="/struts">
改成：<package name="struts" extends="struts-default" namespace="/">
第二种解决方案：
在webroot下建立个struts文件夹，然后把那个jsp页面放入进去
OK搞定，还不快去试试
