POST "/ @% 7B / логин% 7D", параметры = {маскировано}

Question

Когда я нажимаю на форму входа после ввода учетных данных, она показывает

Белая метка Страница ошибки.
Это приложение не имеет явного сопоставления для / error, поэтому вы видите это как запасной вариант .

Произошла непредвиденная ошибка (тип = Не найдено, статус = 404).
Сообщение недоступно

После ввода url "/ login" автоматически становится "http://localhost: 8080 / @% 7B / login% 7D ".

Вот код моего контроллера

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(@RequestParam("email") String email, @RequestParam("password") String password, ModelMap modelMap) {
    User user = userRepository.findByEmail(email);
    if (user.getPassword().equals(password)) {
        return "findFlight";
    } else {

        modelMap.addAttribute("msg", "nvalid username or password .please tryagain");

    }
    return "login/login";
}

вот логин. html файл

<form action="@{/login}" method="post" >
    <div class="imgcontainer">
        <img th:src="@{/imgs/img_avatar2.png}" alt="Avatar" class="avatar">
    </div>

    <div class="container">
        <label for="email"><b>email</b></label>
        <input type="text" placeholder="Enter Username" name="email" required>

        <label for="psw"><b>Password</b></label>
        <input type="password" placeholder="Enter Password" name="password" required>

        <button type="submit">Login</button>
        <label>
            <input type="checkbox" checked="checked" name="remember"> Remember me
        </label>
    </div>

    <div class="container" style="background-color:#f1f1f1">
        <button type="button" class="cancelbtn">Cancel</button>
        <span class="psw">Forgot <a href="#">password?</a></span>
    </div>
</form>
