There is no Action mapped for namespace / and action name user_login.
初学框架,不知道哪里写错了。求指点!

    struts.xml的配置有没有配置,可以贴出来看下,这种错误一般是配置有问题引起的



    /online/datashow/list.jsp
    /online/datashow/listlog.jsp

    user_queryInfo.action
    /index.jsp
    /userList.jsp

    如果userAction是用spring管理的话,是不用带路径的
    可以把@Controller改成@Controller("userAction")

    根据 Struts.xml中的配置
    login.jsp中的

    应该改为

    根据 配置 后缀应该是 xhtml
    user_login改成 user_login.xhtml
