Servlet页面跳转到jsp并且传递数据对象实例，servlet如何实现页面之间的跳转？jsp接收servlet跳转传递的数据的实例，dispatcher.forward方法使用：
Servlet_Forward.java文件：
package com.cn.forward;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Servlet_Forward extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String value = request.getParameter(“value”);
if(value !=null || value !=”"){
if(value.equals(“jsp”)){
// 传递一个 Date 对象给 JSP 页面
request.setAttribute(“date”, new Date());
RequestDispatcher dispatcher = request.getRequestDispatcher(“/index.jsp”);
dispatcher.forward(request, response);
}
}
}
}
接收数据的jsp文件index.jsp：
<%@ page language=”java” contentType=”text/html; charset=UTF-8″ %>
<jsp:directive.page import=”java.util.Date”/>
<jsp:directive.page import=”java.text.SimpleDateFormat”/>
<%
Date date = (Date)request.getAttribute(“date”);
%>
