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; } }
