data source configuration 


@Configuration
@MapperScan("com.su.api.db.mapper")
public class DataConfig {

    @Bean
    public DataSource dataSource() {

        SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
        dataSource.setDriverClass(com.mysql.jdbc.Driver.class);
        dataSource.setUsername("root");
        dataSource.setUrl("jdbc:mysql://localhost:3306/esstat?useSSL=false&serverTimezone=UTC");
        dataSource.setPassword("root");
        return dataSource;
    }


   @Bean
   public DataSourceTransactionManager transactionManager()
   {
       return new DataSourceTransactionManager(dataSource());
   }

   @Bean
   public SqlSessionFactoryBean sqlSessionFactoryBean() throws Exception{
       System.out.println("set sqlSessionFactory");
       SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
       sessionFactory.setDataSource(dataSource());

       sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:/mapper/*.xml"));


       return sessionFactory;
   }


}

пользовательский интерфейс, который находится в пути @mapperScan 

public interface User {

    public String  FIELD_USER_NUM = "user_num";
    public String FIELD_ID = "id";
    public String FIELD_PASSWORD = "password";
    public String FIELD_LAST_LOGIN = "last_login";
    public String FIELD_LAST_LOGIN_ip = "last_login_ip";
    public String FIELD_CREATED_DATE = "created_date";


    public int getCount();
    public Map getUser(String id);
}

custom userDetailsService 

public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    BCryptPasswordEncoder encoder;

    @Autowired
    User user;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        // TODO Auto-generated method stub

        LoginUser loginUser =  new LoginUser(username, username, false, false, false, false, null);
        return loginUser;
    }

В пользовательском классе UserDetailsService я пытаюсь получить информацию о пользователе из базы данных пользователем 

@Autowired User user

Однако возникает ошибка ..

Я протестировал пользователя @Autowired User в классе Controller и обнаружил, что все работает нормально.

Ошибка возникает при запуске tomcat. Итак, я не могу получить информацию о пользователе из базы данных. Как я могу решить эту проблему ??

Согласно предоставленному коду пользователь здесь интерфейс, а не класс. Когда мы помечаем любую ссылку аннотацией @Autowired, то Spring ожидает, что это будет либо класс bean-компонента Spring, либо должен существовать хотя бы один реализующий класс EJB-компонента для того же класса, и этот класс необходимо пометить аннотацией стереотипа, т. Е. @Component. или настройте как @Bean в своем классе конфигурации Spring. Например, 

@Component
class User {

//Attributes
}

или если вы хотите сделать его Spring bean с помощью аннотации @Bean, вы можете сделать это так же, как и для других в вашем классе конфигурации, как показано ниже 

class SpringBeanConfiguration {

   @Bean
   public User user() {
     return new User();
   }
}
