jsp和servlet中实现页面跳转的方式实例总结_JSP编程_

<% RequestDispatcher rd = getServletContext().getRequestDispatcher("/test/test2.jsp"); rd.forward(request, response); %>

<% response.sendRedirect("test2.jsp"); %>

<% int stayTime=0; String URL="test2.jsp"; String content=stayTime+";URL="+URL; response.setHeader("REFRESH",content); %>

<% response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); String newLocation = "test2.jsp"; response.setHeader("Location",newLocation); %>

 ServletContext sc = getServletContext(); RequestDispatcher rd = sc.getRequestDispatcher("/test/test2.jsp"); //定向的页面 rd.forward(request, response); public class ForwardServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String id = request.getParameter("id"); response.setContentType("text/html; charset=gb2312"); ServletContext sc = getServletContext(); RequestDispatcher rd = sc.getRequestDispatcher("/test/test2.jsp"); //定向的页面 rd.forward(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request, response); } }
