Spring Boot: источник данных Autowiring Null

0 голосов
/ 18 февраля 2020

Я перевожу существующее приложение на основе Spring в Spring Boot. Я пытаюсь настроить источник данных в следующем формате.

1) Application.properties 

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=
databaseName=
spring.datasource.username=
spring.datasource.password=

2) @Configuration bean с кодом ниже 

@Configuration
public class DatabaseConfig {

  @Value("${spring.datasource.driverClassName}")
  private String driverClassName;

  @Value("${spring.datasource.url}")
  private String url;

  @Value("${spring.datasource.username}")
  private String userName;

  @Value("${spring.datasource.password}")
  private String password;

  @Primary
  @Bean(name ="OneDataSource")
  public DataSource getDataSource() {

    HikariConfig config = new HikariConfig();
    config.setDriverClassName(driverClassName);
    config.setJdbcUrl(url);
    config.setUsername(userName);
    config.setPassword(password);
    HikariDataSource hds=new HikariDataSource(config);
    return hds;
  }
}

И при попытке использовать этот источник данных в одном из классов с помощью приведенного ниже кода 

@Autowired
@Qualifier("OneDataSource")
private DataSource dataSource ;

ниже приведен код, используемый в методе (это существующий код, используемый в приложении Spring 1) this.connect = dataSource.getConnection ( );

Мой источник данных пуст, и я получаю сообщение об ошибке ниже 

java.lang.NullPointerException: null
