标题: struts2.1.X关于配置redirect-action启动出错的解决方法
最近在学习Struts2,在配置struts-spring.xml的时候,我的配置文件struts-spring.xml如下:
  1. <action name="userlogin" class="UserLoginAction" method="userlogin">
  2.         <result name="success" type="redirect-action">
  3.                 <param name="actionName">login</param>
  4.                 <param name="namespace">/</param>
  5.         </result>
  6.         <result name="error">/login.jsp</result>
  7. </action>
复制代码
然后我启动TOMCAT,出现如下错误

在网上搜索了一通,发现原来我前面的那个配置是支持struts2.0.X的配置,而我的struts的JAR的版本为struts2.1.6,在struts2.1.X中针对redirect-action的配置全面变了.配置如下:
  1. <action name="userlogin" class="UserLoginAction" method="userlogin">
  2.         <result name="success" type="redirectAction">
  3.                 <param name="actionName">login</param>
  4.                 <param name="namespace">/</param>
  5.         </result>
  6.         <result name="error">/login.jsp</result>
  7. </action>
复制代码
最后发现奇迹出现了,成功了!
