Spring Javaconfig basiert autowire by name funktioniert nicht

Ich versuche, mit Javaconfig-basierte Spring-Konfigurationen. Ich habe zwei Bohnen der gleichen Art und versuchen, autowire Sie durch die Qualifier. Aber es scheint nicht zu arbeiten.

Dies ist meine Konfiguration, Klasse

    @Configuration
    @EnableAutoConfiguration
    @ComponentScan("com.test")
    public class BasicConfig {
        @Bean(name = "mysqlSource")
        @Qualifier("mysqlSource")
        public DataSource jdbcTemplateMySql() {
            BasicDataSource dataSource = new BasicDataSource();
            dataSource.setDriverClassName("com.mysql.jdbc.Driver");
            dataSource.setUrl("jdbc:mysql://localhost:3306/db1?useUnicode=true&characterEncoding=UTF-8");
            dataSource.setUsername(mysqlUser);
            dataSource.setPassword(mysqlPass);
            return dataSource;
        }

        @Bean(name = "oracleSource")
        @Qualifier("oracleSource")
        public DataSource jdbcSourceOracle() {
            BasicDataSource dataSource = new BasicDataSource();
            dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver");
            dataSource.setUrl("jdbc:oracle:thin:@lab-scan.tigeritbd.com:1521/evidb.tigeritbd.com");
            dataSource.setUsername(oracleUser);
            dataSource.setPassword(oraclePass);
            return dataSource;
        }
    }

 

Dies sind meine beiden anderen Klassen, wo ich bin versucht, autowire Sie.

 
    @Repository
    public class TrackingInfiniDBRepo implements DataPutRepo {
        private NamedParameterJdbcTemplate jdbcTemplate;

        @Autowired
        void setJdbcTemplateOracle(@Qualifier("mysqlSource") DataSource dataSource) {
            jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
        }
    }
     


    @Repository
    public class OracleDataFetcherRepo implements DataFetcherRepo {
        private NamedParameterJdbcTemplate jdbcTemplateOracle;
        @Autowired
        void setJdbcTemplateOracle(@Qualifier("oracleSource") DataSource dataSource) {
            jdbcTemplateOracle = new NamedParameterJdbcTemplate(dataSource);
        }
    }
     

Aber wenn ich anfange meine Bewerbung per ConfigurableApplicationContext context = SpringApplication.run(BasicConfig.class) wirft er eine exception.

Ich bin aus der Idee. Ich habe versucht zu google, aber alle scheint nahe zu legen, hinzufügen Qualifier. Aber ich habe schon hinzufügen, dass aber ohne Einsatz. Bitte helfen Sie. Ich bin mit Spring 4(aktuelle version).
