Форма входа выбрасывает неверное имя пользователя или пароль, хотя имя пользователя и пароль верны

Question

Я посмотрел учебник о Spring Security и попытался написать приложение с формой входа (для роли администратора).Это работает нормально, но когда я пытаюсь ввести имя пользователя и пароль на странице входа, всегда появляется сообщение об ошибке «Неверное имя пользователя или пароль», хотя у меня были правильные (из базы данных).Ошибка может появиться из-за конфигурации безопасности Spring, но я точно не знаю причину.Может кто-нибудь помочь мне?

LoginController.java

@RequestMapping("/login")
public String login(@RequestParam(value = "error", required = false) String error,
                    @RequestParam (value = "logout", required = false) String logout, Model model) {
    if (error != null) {
        model.addAttribute("error","Invalid username or passwrd");
    }

    if (logout != null ){
        model.addAttribute("msg","you have been logged out successfully");
    }

    return "login";
}

Answer 1

Все решено ... Проблема была в подключении к базе данных.

Answer 2

Параметр запроса является строкой. Так что проверьте также пустую строку.

if (error != null) {
    model.addAttribute("error","Invalid username or passwrd");
}

до

if (error != null && !error.isEmpty()) {
    model.addAttribute("error","Invalid username or passwrd");
}
