Question

我有3个链接，教师，学生和员工。当点击任何链接时，我希望它们转到Selection servlet，servlet将检查选择了哪个链接。之后，它会将其转发到所需的JSP页面。我不知道该怎么做。

到目前为止，这是我的代码：

JSP文件：

<!DOCTYPE html>
<html>
<head>
    <title>Selection</title>
</head>
<body>
    <h2>Please Choose One</h2>

    <a name="select" value= "Teacher" href="UserSelection"> Teacher </a> <!-- Not sure if I need name and value -->

    <a name="select" href="UserSelection"> Student </a> 

    <a name="select" href="UserSelection"> Employee </a>

</body>
</html>

选择Servlet：

@WebServlet("/UserSelection")
public class UserSelection extends HttpServlet 
{
    private static final long serialVersionUID = 1L;

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

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
    {
        String selection = request.getParameter("select");

        if("Teacher".equals(selection))
        {
            System.out.println("Teacher");
        }

    }

}

在JSP中创建一个链接，链接到另一个JSP
