解决方案 »

  1.   

    <html:form action="user.do">
      

  2.   

    <html:form action="/user.do">
      

  3.   

    改成<html:form action="/user.do">
    也没用呀弄了两天了，是照着一个视频做的
      

  4.   

    你的Action名字叫UserAction
    但是struts-config.xml配置文件里写的type="org.springframework.web.struts.DelegatingActionProxy" 
    名字不对，肯定找不到action类啊
    type的值应该是
    type="org.tie.struts.action.UserAction"是你的action类的地址
      

  5.   

    另外<html:form action="/user.do"> 
    最好写成这样！
      

  6.   

    <bean name="/user" singleton="false" class="org.tie.struts.action.UserAction"
    abstract="false"  lazy-init="default" 
    autowire="default"  dependency-check="default">  红色的地方错了吧
      

  7.   

    <action-mappings > 
          <action path="/user" 
        type="org.springframework.web.struts.DelegatingActionProxy" 
         name="userForm"> 
            <forward name="success" path="/success.jsp" /> 
            <forward name="failure" path="/index.jsp" /> 
          </action> 
    改成你对应的useraction页面访问user.do
      

  8.   

    <action-mappings >  
           <action path="/user"  
        type="org.springframework.web.struts.DelegatingActionProxy"  
         name="userForm">  
             <forward name="success" path="/success.jsp" />  
             <forward name="failure" path="/index.jsp" />  
           </action>  
    改为：
    <action-mappings >  
           <action path="/user"  
        type="org.tie.struts.action.UserAction"  
         name="userForm">  
             <forward name="success" path="/success.jsp" />  
             <forward name="failure" path="/index.jsp" />  
           </action>
      

  9.   

    这是struts+spring 结构的，<bean name="/user" singleton="false" class="org.tie.struts.action.UserAction"
    abstract="false"  lazy-init="default" 
    autowire="default"  dependency-check="default">   应该是你的spring 配置问题。
      

  10.   

    <action-mappings >  
            <action path="/user"  
        type="org.springframework.web.struts.DelegatingActionProxy"  
         name="userForm">  
              <forward name="success" path="/success.jsp" />  
              <forward name="failure" path="/index.jsp" />  
            </action>  
    改为：
    <action-mappings >  
            <action path="/user"  
        type="org.tie.struts.action.UserAction"  
         name="userForm">  
              <forward name="success" path="/success.jsp" />  
              <forward name="failure" path="/index.jsp" />  
            </action>
    这样改不对哇   struts+spring整合 就是要将type="org.tie.struts.action.UserAction" 改成type="org.springframework.web.struts.DelegatingActionProxy" 
      

  11.   

      呵呵 我不告诉你，应该是你的spring 配置问题乐吗？
      

  12.   

    spring 配置文件里面还需要配置 ACTION 你不知道吗?
      

  13.   

    applicationContext.xml 里面 添加action配置:
    <bean name="/user" class="org.tie.struts.action.UserAction">
    </bean>
      

  14.   

    applicationContext.xml 里面没有action配置嘛
    有的呀
