Servlet實現定時刷新到另外一個頁面response.setHeader("refresh", "3;url=/...")

想要實現，訪問Responsedemo11的時候，3秒鍾后，跳轉到ResponseDemo10

用   response.setHeader("refresh", "3;url=/ResponseDemo/ResponseDemo10");   實現。  這個refresh是使用get方式跳轉，url中可以攜帶參數和數據。

 

ResponseDemo11代碼：

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 實現3秒鍾后跳轉到另外一個頁面 
 */
@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("進入了demo11,接下來3秒鍾后進入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（跳轉后的頁面）的代碼：

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 這個是用來被跳轉的頁面
 */
@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("這個是被跳轉后的頁面       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);
    }

}
