页面定时跳转
package cn.edu.Response;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Random;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class ResponseDemo5 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//假设这是一个处理用户登录的servlet
//假设程序运行到此，用户登陆成功了
String message="恭喜你，登陆成功，本页面将在3秒内跳转，若没有跳转，请点击超链接";
this.getServletContext().setAttribute("message",message);
this.getServletContext().getRequestDispatcher("/message.jsp").forward(request, response);
}
private void text2(HttpServletResponse response) throws IOException {
//假设这是一个处理用户登录的servlet
//假设程序运行到此，用户登陆成功了
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
response.setHeader("refresh", "3;url='/day06/index.jsp'");
response.getWriter().write("恭喜你，登陆成功，本页面将在3秒内跳转，若没有跳转，请点击超链接");
}
private void text1(HttpServletResponse response) throws IOException {
response.setHeader("refresh", "3");
String data = new Random().nextInt(10000) + "";
response.getWriter().write(data);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}控制浏览器缓存
package cn.edu.Response;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//控制浏览器缓存
public class ResponseDemo6 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setDateHeader("expires", System.currentTimeMillis()+1000*3600);
String data="aaaaaaaaaaaa";
response.getWriter().write(data);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
}
