Servlet请求转发

没有办法直接访问WEB-INF

可以通过请求跳转的方式进行

    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//        获取请求的参数（办事材料）查看
        String username = req.getParameter("username");
        System.out.println("在Servlet1（柜台）中查看参数（材料）：" + username);

//        给材料盖一个章，并传递到Servlet2中查看（柜台2）去查看
        req.setAttribute("key1","柜台1的章");

//        跳转到servlet2
        RequestDispatcher requestDispatcher = req.getRequestDispatcher("/servlet2");
        requestDispatcher.forward(req,resp);
    }
