welcome-file-list不能直接写action地址

 

 

 

web.xml中这样配置 
<welcome-file-list> 
  <welcome-file>index.jsp</welcome-file> 
</welcome-file-list> 

然后在index.jsp中使用Struts2的标签 
<s:action name="getDataInfo" executeResult="true"></s:action> 

这个标签会执行这个action,然后返回结果页面.

 

 

web.xml中这样配置 
<welcome-file-list>
		<welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>
然后在welcome.jsp使用jsp内置对象跳转或转发
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<% /*  response.sendRedirect("medicine/title");  //重定向*/
    request.getRequestDispatcher("medicine/title").forward(request,response);//转发%>

 

 

web.xml 
 <welcome-file-list> 
 <welcome-file>jump.jsp </welcome-file> 
 </welcome-file-list> 
 
jump.jsp里通过这段代码访问action': 
 <meta http-equiv='refresh'  content='0;url=show.action'>

 

 

<welcome-file-list>
 <welcome-file>index.jsp </welcome-file>
 </welcome-file-list>
 
index.jsp里
 <jsp:forword page="show.action">
