嗨，我正在为登录表单做下面的Java代码，它没有将我重定向到employee.jsp或customer jsp页面

Question

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    try {
        user user = new user();
        user.setUsername(request.getParameter("username"));
        user.setPassword(request.getParameter("password"));
        user = loginBean.Login(user);
        if (user.getMessage() == null || user.getMessage().equals("")) {
            request.setAttribute("message", user.getMessage());
        }
        if (user.getRole().equals("Employee")) {
            request.getRequestDispatcher("/employee.jsp").forward(request, response);
        } else {
            request.getRequestDispatcher("/customer.jsp").forward(request, response);
        }
    } catch (Exception ex) {
        System.out.println(ex);
    }

}

Answer 1

What you are trying to do is after a successful login redirect the user to employee.jsp or customer.jsp depending on their role.

You currently forward the request on to employee.jsp or customer.jsp along with all the parameters (username, password and message and anything else).

What you need to do is redirect the user to the new page like this:

if (user.getRole().equals("Employee")) {
    response.sendRedirect("/employee.jsp");
} else {
    response.sendRedirect("/customer.jsp");
}

Answer 2

Make Sure that u had these pages in your project directory . If they are not there you get error message. your code is right

 if (user.getRole().equals("Employee")) {
response.sendRedirect("/employee.jsp");} else {
response.sendRedirect("/customer.jsp");}
