NoUniqueBeanDefinitionException: no se define ningún bean calificador de tipo[javax.persistence.EntityManagerFactory]: bean de coincidencia única esperado

Question

Tengo 2 bases de datos separadas y estoy tratando de acceder a ellas en los repositorios. Lamentablemente estoy recibiendo la siguiente excepción.

Cosas que he intentado

• he intentado hacer uno de los frijoles como Primario .
• han utilizado PersistenceContext como se puede ver en el código a continuación.

Mi orden de control que es simplemente Repositorio de Autowiring

@RestController
@RequestMapping("/Order")
public class OrderController {

    @Autowired
    private OrderRepository nextGenorder;

Mi orden Repositorio tiene

@Repository
public class OrderRepository extends AbstractRepository<Order> implements
        OrderRepositoryInterface {
    private static final String SELECT_QUERY = "select p from v_orders p";
    @PersistenceContext(name = "nextGenEntityManagerFactory")
    private EntityManager nextGenEntityManagerFactory;;

    public EntityManager getEntityManager() {
        return nextGenEntityManagerFactory;
    }

    public void setEntityManager(EntityManager entityManager) {
        this.nextGenEntityManagerFactory = entityManager;
    }

    public List<Order> selectAll() {
        javax.persistence.Query query = nextGenEntityManagerFactory
                .createQuery(SELECT_QUERY);
        List<Order> order = query.getResultList();
        return order;
    }

Mi archivo FirstConfig

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "xx.xx.xx.crud.repository.running", entityManagerFactoryRef = "nextGenEntityManagerFactory", transactionManagerRef = "transactionManagerOne")
@PropertySource("classpath:application.properties")
public class NextGenDbConfig {

    @Value("${spring.datasourcemymerkNew.driver-class-name}")
    String driverClassName = "";
    @Value("${spring.datasourcemymerkNew.url}")
    String url = "";
    @Value("${spring.datasourcemymerkNew.username}")
    String userName = "";
    @Value("${spring.datasourcemymerkNew.password}")
    String password = "";
    @Autowired
    @Qualifier("jpaNextGenVendorApapter")
    JpaVendorAdapter jpaNextGenVendorApapter;

    @Bean(name = "nextGenDataSource")
    @Primary
    public DataSource nextGenDataSource() {
        return DataSourceBuilder.create().url(url)
                .driverClassName(driverClassName).username(userName)
                .password(password).build();
    }

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean nextGenEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        factoryBean.setDataSource(nextGenDataSource());
        factoryBean.setJpaVendorAdapter(jpaNextGenVendorApapter);
        factoryBean.setPackagesToScan(R.nextGenDB_PACKAGE);
        factoryBean.setPersistenceUnitName("nextGenPersistenceUnit");
        factoryBean.setJpaProperties(additionalProperties());

        return factoryBean;
    }

    @Bean
    PlatformTransactionManager transactionManagerOne() {
        return new JpaTransactionManager(nextGenEntityManagerFactory()
                .getObject());
    }

    @Bean(name = "jpaNextGenVendorApapter")
    @Primary
    public JpaVendorAdapter jpaNextGenVendorAdapter() {
        HibernateJpaVendorAdapter jpaNextGenVendorAdapter = new HibernateJpaVendorAdapter();
        jpaNextGenVendorAdapter.setShowSql(true);
        jpaNextGenVendorAdapter.setGenerateDdl(true);
        jpaNextGenVendorAdapter.setDatabase(Database.MYSQL);
        return jpaNextGenVendorAdapter;
    }

    Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect",
                "org.hibernate.dialect.MySQL5Dialect");
        return properties;
    }

    @Bean
    public HibernateExceptionTranslator hibernateExceptionTranslator() {
        return new HibernateExceptionTranslator();
    }

}

y segunda configuración

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.mymerkbiotech.blueberry.crud.repository.running", entityManagerFactoryRef = "mymerkLimsEntityManagerFactory", transactionManagerRef = "transactionManagertwo")
@PropertySource("classpath:application.properties")
public class mymerkDbConfig {

    @Value("${spring.datasourcemymerkLims.driver-class-name}")
    String driverClassName = "";
    @Value("${spring.datasourcemymerkLims.url}")
    String url = "";
    @Value("${spring.datasourcemymerkLims.username}")
    String userName = "";
    @Value("${spring.datasourcemymerkLims.password}")
    String password = "";
    @Autowired
    @Qualifier("jpamymerkVendorAdapter")
    JpaVendorAdapter mymerkVendorAdapter;

    @Bean(name = "mymerklimsDataSource")
    public DataSource mymerklimsDataSource() {
        return DataSourceBuilder.create().url(url)
                .driverClassName(driverClassName).username(userName)
                .password(password).build();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean mymerkLimsEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        factoryBean.setDataSource(mymerklimsDataSource());

        factoryBean.setJpaVendorAdapter(mymerkVendorAdapter);
        factoryBean.setPackagesToScan(R.mymerkDB_PACKAGE);
        factoryBean.setPersistenceUnitName("mymerklimsPersistenceUnit");
        factoryBean.afterPropertiesSet();

        return factoryBean;
    }

    @Bean
    PlatformTransactionManager transactionManagerTwo() {
        return new JpaTransactionManager(mymerkLimsEntityManagerFactory()
                .getObject());
    }

    @Bean(name = "jpamymerkVendorAdapter")
    public JpaVendorAdapter jpamymerkVendorAdapter() {
        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setShowSql(true);
        jpaVendorAdapter.setGenerateDdl(true);
        jpaVendorAdapter.setDatabase(Database.MYSQL);
        return jpaVendorAdapter;
    }

    Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect",
                "org.hibernate.dialect.MySQL5Dialect");
        return properties;
    }

}

Probé la depuración en PersistenceAnnotationBeanPostProcessor pero se perdió pronto.

Answer 1

Creo que debería nombrar sus LocalContainerEntityManagerFactoryBean en ambas configuraciones. Por lo tanto, debería verse así:

@Bean(name = "nextGenEntityManagerFactory")
@Primary
public LocalContainerEntityManagerFactoryBean nextGenEntityManagerFactory() {

para el primero y

@Bean(name = "gatcLimsEntityManagerFactory") 
public LocalContainerEntityManagerFactoryBean gatcLimsEntityManagerFactory() {

para el segundo.
