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