这是一个名为

的动作调用的JSP页面

<body>      
 hi welcome to
 <s:property value="username" />
 <s:submit action="allrecords" value="All Records Show"></s:submit>                
</body>

列表项

在struts xml中：

<struts>

   <constant name="struts.mapper.action.prefix.enabled" value="true" />

   <constant name="struts.devMode" value="true" />
   <constant name="struts.enable.DynamicMethodInvocation" value="true" />
   <constant name="struts.custom.i18n.resources"             value="ApplicationResources"/> 

  <include file="loginfirst.xml"></include>

  <package name="default" extends="struts-default">

    <action name="reguser">
        <result>/login.jsp</result>
    </action>

    <action name="loginprocess" class="com.org.struts.Loginprocess">

        <result name="success">/success.jsp
        </result>
        <result name="error">/login.jsp
        </result>
        <result name="input">/login.jsp</result>

    </action>

    <action name="allrecords" class="com.org.struts.FetchRecords">

        <result name="success">/allrecords.jsp
        </result>
    </action>



  </package>


  <package name="default" namespace="/legends" extends="struts-default">
    <action name="gettutorial" class="com.org.struts.Tutorial">

        <result name="success">/success.jsp
        </result>
        <result name="error">/error.jsp
        </result>

    </action>

    <action name="addtutorial" class="com.org.struts.Tutorial"
        method="addmethod">

        <result name="success">/success.jsp
        </result>
        <result name="error">/error.jsp
        </result>

    </action>

    </package>
</struts>

这里的动作类

public class FetchRecords extends ActionSupport   {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    /**
     * 
     */
    ArrayList<User> list=new ArrayList<User>();  

    public ArrayList<User> getList() {  
        return list;  
    }  
    public void setList(ArrayList<User> list) {  
        this.list = list;  
    }  
    public String execute(){  
     try{  
      Class.forName("com.mysql.jdbc.Driver");  
      Connection con=DriverManager.getConnection(  
              "jdbc:mysql://localhost:3306/strutssampleform", "root", "");  

      PreparedStatement ps=con.prepareStatement("select * from USER_DETAIL");  
      ResultSet rs=ps.executeQuery();  

      while(rs.next()){  
       User user=new User();  
       user.setFirstName(rs.getString(1));  
       user.setLastName(rs.getString(2));  
       user.setUsername(rs.getString(3));  
       user.setEmailid(rs.getString(5));  
       list.add(user);  
      }  

      con.close();  
     }catch(Exception e){e.printStackTrace();}  

     return "success";  
    }

}

列表项

allrecords显示jsp

<s:iterator  value="list">  
<fieldset>  
<s:property value="firstName"/><br/>  
<s:property value="lastName"/><br/>  
<s:property value="username"/><br/>

你说提交行动无效。我想你有submit标签不起作用。将action属性与submit标记一起使用的问题。默认情况下，此功能已禁用。您可以尝试删除操作属性并将表单映射到操作。

<s:form action="allrecords">
 ...
 <s:submit value="All Records Show"/>
</s:form>
