Так как вы сделали '' username' и password' по желанию, это лучше, чтобы проверить их ничтожности перед передачей их в 'getUserByLoginPaswword'. Что-то вроде 'if (username! = Null && password! = Null && userDao.getUserByLoginPaswword (login, password)! = Null)'. –

Кроме того, удалите аннотацию стереотипа '@ Configuration' из' LoginController' –

– batman

NullPointerException стеблями от

dao.UserDAO.getUserByLoginPaswword(UserDAO.java:24)

и если я насчитал право Thats эту строку:

UserDTO user = jdbcTemplate.queryForObject(....

И в вашем коде это также выглядит как JdbcTemplate равно нулю. Не автоувеличивается. Добавьте аннотацию @Autowired в поле jdbcTemplate или установщик, и он должен работать.

Если вы не добавили точку останова в строке 24 и внимательно посмотрите, что там неожиданно было null.

Я добавил Аннотированный ' @ Autowired' over 'jdbcTemplate', теперь у меня есть ошибка '... Не удалось autowire field: org.springframework.jdbc.core.JdbcTemplate dao.UserDAO.jdbcTemplate; Вложенное исключение - это org.springframework.beans.factory.NoSuchBeanDefinitionException: не существует определяющего компонента типа [org.springframework.jdbc.core.JdbcTemplate], найденного для зависимости: ожидается как минимум 1 компонент, который квалифицируется как кандидат на автоподключение для этой зависимости. Аннотации зависимостей: {@ org.springframework.beans.factory.annotation.Autowired (обязательно = истина)}» – batman

ой я глупо ......
вместо
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.2.5.RELEASE</version> </dependency>
нужно использовать
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency>
затем весной создать DataSource и JdbcTemplate

Источник данных должен быть введен через сеттер на основе инъекции или на основе конструктора. Попробуйте это, и я надеюсь, что это сработает.

@Repository 
public class UserDAO { 
JdbcTemplate jdbcTemplate; 

public JdbcTemplate getJdbcTemplate() { 
    return jdbcTemplate; 
} 

@Autowired 
public void setJdbcTemplate(final DataSource dataSource) { 
    this.jdbcTemplate = new JdbcTemplate(dataSource); 
} 



public UserDTO getUserByLoginPaswword(String login, String password) { 
    String sql = "SELECT* FROM epam_db.users WHERE login=? and password=?"; 

    UserDTO user = jdbcTemplate.queryForObject(sql, new Object[] { login, password }, new UserMapper()); 
    return user; 

    } 
}
