Репозиторий данных JPA — найдено 2 bean-компонента типа EntityManager

Я пытаюсь настроить второй источник данных в своем приложении Spring. Ниже приведены 2 класса конфигурации для 2 источников данных:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.XYXYale.persistence.XY",
        entityManagerFactoryRef = "awEntityManagerFactory",
        transactionManagerRef= "awTransactionManager"
)
public class Datasource1DataSourceConfig {

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

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

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

    @Value("${spring.first-datasource.driver-class-name}")
    private String driver;


    @Bean
    @Primary
    @ConfigurationProperties("spring.first-datasource")
    public DataSourceProperties awDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @Primary
    @Qualifier("awEntityManagerFactory")
    public DataSource awDataSource() {

        DriverManagerDataSource dataSource
                = new DriverManagerDataSource();
        dataSource.setDriverClassName(
                driver);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(pw);

        return dataSource;
    }

    @Primary
    @Bean(name = "awEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean awEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(awDataSource());
        em.setPersistenceUnitName("XY");



");
        em.setPackagesToScan(new String[] { "com.XY.XY.domain.XY" });
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");
        em.setJpaVendorAdapter(vendorAdapter);
        return em;
    }

    @Primary
    @Bean
    public PlatformTransactionManager awTransactionManager() {
        JpaTransactionManager transactionManager
                = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(
                awEntityManagerFactory().getObject());
        return transactionManager;
    }

}

Второй класс конфигурации:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.XYXYale.persistence.YX",
        entityManagerFactoryRef = "sndEntityManagerFactory",
        transactionManagerRef= "sndTransactionManager"
)
public class SndDataSourceConfig {

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

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

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

    @Value("${spring.second-datasource.driver-class-name}")
    private String driver;

    @Bean
    @ConfigurationProperties("spring.second-datasource")
    public DataSourceProperties sndDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @Qualifier("sndEntityManagerFactory")
    public DataSource sndDataSource() {
        DriverManagerDataSource dataSource
                = new DriverManagerDataSource();
        dataSource.setDriverClassName(
                driver);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(pw);

        return dataSource;
    }

    @Bean(name = "sndEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean sndEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(sndDataSource());
        em.setPersistenceUnitName("snd");
        em.setPackagesToScan(new String[] { "com.XY.XY.domain.YX" });
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");
        em.setJpaVendorAdapter(vendorAdapter);
        return em;
    }

    @Bean
    public PlatformTransactionManager sndTransactionManager() {
        JpaTransactionManager transactionManager
                = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(
                sndEntityManagerFactory().getObject());
        return transactionManager;
    }

}

У меня есть в com.XYXYale.persistence.XY репозиторий Spring данных JPA, определенный следующим образом

Демо-репозиторий

@Repository
public interface DemoRepo extends CrudRepository<Demo, String>, DemoRepoCustom{
}

ДемоРепоПользовательский

@NoRepositoryBean
public interface DemoRepoCustom {
    Demo returnDemoContent();
}

DemoRepoImpl

public class DemoRepoImpl extends QuerydslRepositorySupport implements DemoRepoCustom {

    public DemoRepoImpl() {
        super(Demo.class);
    }

    public Demo returnDemoContent(){
        return something;
    }

}

Репо используется следующим образом

@Autowired
DemoRepo demoRepo;

Я получаю это исключение:

У кого-нибудь есть предложение о том, как это решить? Я мог бы подумать о том, чтобы ввести правильный менеджер сущностей в каждое репо, однако я понятия не имею, как это сделать.

Заранее спасибо. Не могу найти решение ни здесь, ни на других сайтах.
