分享struts2访问.do出现404错误的问题
就拿登录来说：
1.login.jsp
2.struts.xml
3.web.xml
在com.daowen.action.AdminLogin内进行了重定向跳转页面的，所以struts里面没有写result
目录结构
jar包
运行结果
请问为什么出现404错误？

<filter-mapping>
<filter-name>自定义的</filter-name>
<url-pattern>*.do</url-pattern>
<url-pattern>*.action</url-pattern>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
你按这个配置下

先看看index.jsp能不能打开，再试下把配置改成这样<action name="login" class="com.daowen.action.AdminLogin123456">
</action>以确定配置文件是否正确加载。
