Question

利用<jsp: forward>传递参数，在被传递的页面上怎么引用传过来的值？

<jsp:forward page="in.jsp">
<jsp:param name="aa" value="bb"/>
<jsp:param name="aa11" value="bb11"/>
</jsp:forward>

请问怎么在in.jsp上引用aa？

Answer 1

index.jsp<%@ page language="java" pageEncoding="GBK"%>
<jsp:forward page="in.jsp">
<jsp:param name="aa" value="bb"/>
<jsp:param name="aa11" value="bb11"/>
</jsp:forward>
in.jsp<%@ page language="java" pageEncoding="GBK"%>
<%
String aa=request.getParameter("aa");
String aa11=request.getParameter("aa11");
%>
<%=aa %><br>
<%=aa11 %><br>
