Web_Servlet和jsp页面数据交互，通过请求转发在jsp中显示数据
1.Servlet页面代码
/*
实现jsp页面和sevlet页面的信息交互
*/
@WebServlet(urlPatterns = "/aa")
public class JspService extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//以键值对存储数据
request.setAttribute("name","张三丰");
//进行页面跳转，把信息传过去
request.getRequestDispatcher("/demojsp.jsp").forward(request,response);
}
}2.Jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>

<body>
<div>
<font color="#808080"><%=request.getAttribute("name")%></font>
