Ошибка создания бина с именем приложения EntityManagerFactory с двумя базами данных

Question

Я хочу использовать две базы данных в своем проекте, поэтому я завершил это руководство . И это работает нормально, но я хочу использовать Spring 2.1.8, в то время как в этом руководстве используется 1.5.3. Но когда я меняю версию spring в pom.xml, она больше не работает. Может кто-нибудь сказать мне, почему он не работает с новыми версиями весенней загрузки?

Я использую две базы данных postgre и мои app.properties здесь:

# PostgreSQL DB - "foo"
spring.datasource.url=jdbc:postgresql://localhost:5432/newdb?currentSchema=public
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.datasource.driver-class-name=org.postgresql.Driver

# PostgreSQL DB - "bar"
bar.datasource.url=jdbc:postgresql://localhost:5432/secdb?currentSchema=public
bar.datasource.username=postgres
bar.datasource.password=postgres
bar.datasource.driver-class-name=org.postgresql.Driver

Зависимости в pom. xml:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <scope>runtime</scope>
        </dependency>

Entity one:

@Entity
@Table(name = "bar")
public class Bar {
  @Id
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="bar_id_seq")
  @SequenceGenerator(name="bar_id_seq", sequenceName="bar_id_seq", allocationSize=1)
  @Column(name = "ID")
  private Long id;
  @Column(name = "BAR")
  private String bar;
//
}

Entity two:

@Entity
@Table(name = "foo")
public class Foo {
  @Id
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="foo_id_seq")
  @SequenceGenerator(name="foo_id_seq", sequenceName="foo_id_seq", allocationSize=1)
  @Column(name = "ID")
  private Long id;
  @Column(name = "FOO")
  private String foo;
//
}

Хранилище здесь, то же самое для второго объекта. Здесь, если мы используем пружину 2.1.8, мы можем вернуть только «необязательный», но это легко исправить, и проблема не в этом, я думаю

@Repository
public interface BarRepository extends JpaRepository<Bar, Long> {
  Bar findById(Long id);
}

И класс конфигурации для первой базы данных (и почтито же самое для второй сущности): здесь при импорте, если мы используем 1.5.3, мы должны импортировать DataSourceBuilder из org.springframework.boot.autoconfigure.jdbc. , но если мы используем 2.1.8 - это должен быть org.springframework.boot.jdbc. , и это второе, и последнее различие между кодом

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "barEntityManagerFactory",
    transactionManagerRef = "barTransactionManager", basePackages = {"com.foobar.bar.repo"})
public class BarDbConfig {
  @Bean(name = "barDataSource")
  @ConfigurationProperties(prefix = "bar.datasource")
  public DataSource dataSource() {
    return DataSourceBuilder.create().build();
  }
  @Bean(name = "barEntityManagerFactory")
  public LocalContainerEntityManagerFactoryBean barEntityManagerFactory(
      EntityManagerFactoryBuilder builder, @Qualifier("barDataSource") DataSource dataSource) {
    return builder.dataSource(dataSource).packages("com.foobar.bar.domain").persistenceUnit("bar")
        .build();
  }
  @Bean(name = "barTransactionManager")
  public PlatformTransactionManager barTransactionManager(
      @Qualifier("barEntityManagerFactory") EntityManagerFactory barEntityManagerFactory) {
    return new JpaTransactionManager(barEntityManagerFactory);
  }
}

Любая помощь, спасибо
