客户端禁用cookie情况下的URL重写

客户端禁用cookie情况下的URL重写:

servlet:

package com.stono.servlet.listenerorder;
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;
import javax.servlet.http.HttpSession;
public class SessionON extends HttpServlet {
    private static final long serialVersionUID = 1L;
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        HttpSession session = req.getSession();
        // 如果客户端的cookie禁用,每次获得的session都是新的;在chrome Developer Tools中的Cookies界面可以看到没有request的JSESSIONID;
        // 判断获得的session是否是新的;
        boolean new1 = session.isNew();
        System.out.println("session is " + new1);
        PrintWriter writer = resp.getWriter();
        writer.println("com.stono.servlet.listenerorder.SessionON.doGet(HttpServletRequest, HttpServletResponse)");
        // 使用response.sendRedirect(response.encodeRedirectURL("b.do"))进行URL重写;
        // 在客户端可以看到形如:TestBootWeb/b.do;jsessionid=6047B41B7A2D066E803FBA68C88E40F8的格式的URL;
        // 这样在b.do中其session就可以记住当前的页面a.do的session;
        resp.sendRedirect(resp.encodeRedirectURL("b.do"));
        // 在JSP中使用response.encodeURL("xxx.do");进行编写;
    }
}
