6-服务器端转发和客户端重定向

服务端转发

==request.getRequestDispatcher(“demo7”).forward(request,response);==

demo6
public class demo6Servlet extends HttpServlet {

    @Override
    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
     //内部转发
        System.out.println("demo6");
        request.getRequestDispatcher("demo7").forward(request,response);


    }
}

dmeo7
public class demo7Servlet extends HttpServlet {

    @Override
    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //内部转发
        System.out.println("demo7");


    }
}

路径不发生改变

客户端重定向
