Servlet仅在默认开关情况下被调用

此处，当url模式为“ / Login / new”时，不会调用我通过打印到控制台进行验证的servlet。它仅适用于“ / Login”的默认情况

@WebServlet("/Login")
public class UserServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    private UserDAO userDAO;
    
    public void init()
    {
        userDAO = new UserDAO();
    }
    
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        System.out.println("Servlet invoked !!");
        String action = request.getServletPath();
        System.out.println(action);
        switch(action)
        {
        case "/new":
            showNewForm(request,response);
            break;  
        case "/insert":
            insertUser(request, response);
            break;
        case "/update":
            updateUser(request, response);
            break;
        case "/delete":
            deleteUser(request, response);
            break;
        case "/edit":
            showEditForm(request, response);
            break;
        case "/login":
            RequestDispatcher dispatcher= request.getRequestDispatcher("/login.jsp");
            dispatcher.forward(request, response);
            
            
            
        default:
            //listUser(request,response);
            showLogin(request,response);
            break;
        
        
        }

“ /登录”的输出： [

“ /登录/新”的输出：

理想的输出是应调用“ / new”大小写形式的函数。我缺少什么？
