Servlet实现定时刷新到另外一个页面response.setHeader("refresh", "3;url=/...")

想要实现，访问Responsedemo11的时候，3秒钟后，跳转到ResponseDemo10

用   response.setHeader("refresh", "3;url=/ResponseDemo/ResponseDemo10");   实现。  这个refresh是使用get方式跳转，url中可以携带参数和数据。

 

ResponseDemo11代码：

package chensi.com;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet 实现3秒钟后跳转到另外一个页面 
 */
@WebServlet("/ResponseDemo11")
public class ResponseDemo11 extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        response.getWriter().write("进入了demo11,接下来3秒钟后进入demo10");
        response.setHeader("refresh", "3;url=/ResponseDemo/ResponseDemo10");
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

ResponseDemo10（跳转后的页面）的代码：

package chensi.com;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet 这个是用来被跳转的页面
 */
@WebServlet("/ResponseDemo10")
public class ResponseDemo10 extends HttpServlet {
    private static final long serialVersionUID = 1L;
       

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        response.getWriter().write("这个是被跳转后的页面       new page");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}
