Da Sie 'username' und' password' optional gemacht haben, ist es besser, nach ihrer Nichtigkeit zu suchen, bevor Sie sie an 'getUserByLoginPaswword' übergeben. Etwas wie 'if (Benutzername! = Null && Passwort! = Null && userDao.getUserByLoginPasword (Login, Passwort)! = Null)'. –

Löschen Sie auch die '@ Configuration' Stereotyp Annotation von der' LoginController' –

Die Nullpointer Stielen von

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

und wenn ich richtig das ist, diese Zeile gezählt:

UserDTO user = jdbcTemplate.queryForObject(....

Und in Ihrem Code es sieht auch wie jdbcTemplate ist null. Es ist nicht autowired. Fügen Sie die Annotation @Autowired dem Feld jdbcTemplate oder dem Setter hinzu, und es sollte funktionieren.

Wenn nicht, fügen Sie einen Haltepunkt in Zeile 24 hinzu und schauen genau hin, was dort unerwartet Null ist.

Ich fügte Annotated 'hinzu @ Autowired 'über' jdbcTemplate', jetzt habe ich Fehler '... konnte nicht Autowire Feld: org.springframework.jdbc.core.JdbcTemplate dao.UserDAO.jdbcTemplate; verschachtelte Ausnahme ist org.springframework.beans.factory.NoSuchBeanDefinitionException: Kein qualifizierendes Bean vom Typ [org.springframework.jdbc.core.JdbcTemplate] gefunden für Abhängigkeit: erwartet mindestens 1 Bean, das sich als Autowire-Kandidat für diese Abhängigkeit qualifiziert.

oh, ich bin dumm ......
statt

Notwendigkeit, es zu benutzen
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency>
dann feder erstellen und Datasource JDBCTemplate

Die Datenquelle sollte über Setter injiziert werden basierte Injektion oder konstruktorbasierte Injektion. Probieren Sie es aus und ich hoffe, es würde funktionieren.

@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; 

    } 
}
