javaweb例項–網頁的自動重新整理功能實現

做個記錄啊，如果看不懂可以留言，我就不詳細的寫部落格了

建立一個RefreshServelet.java

package cn.kuls.demo1;

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

@WebServlet(name = "RefreshServlet",urlPatterns = "/refresh")
public class RefreshServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws
 
 ServletException, IOException {
       String message="<meta http-equiv='refresh' content='3;url=/hello/sign.html'>3秒後自動跳轉首頁，如果沒有跳轉請點選<a href='/hello/sign.html'>跳轉連結</a>";

        request.setAttribute("message",message);
        request.getRequestDispatcher("/index.jsp").forward(request,response);
    }
//這裡大家可以忽略
 

    private void Refresh(HttpServletResponse response) throws IOException {
        response.setContentType("text/html;charset=utf-8");
        response.setHeader("refresh","3;url='/hello/sign.html' ");
        response.getWriter().print("3s後自動跳轉");
    }
}

然後自然就是寫下跳轉到的介面

簡單粗暴!
