spring NoUniqueBeanDefinitionException: प्रकार की योग्यता सेम नहीं[javax.preistence.EntityManagerFactory] परिभाषित किया गया है: अपेक्षित एकल मिलान बीन



spring-mvc spring-boot (1)

मेरे पास 2 अलग डेटाबेस हैं और मैं उन्हें रिपॉजिटरी में एक्सेस करने का प्रयास कर रहा हूं। दुर्भाग्य से मुझे निम्न अपवाद प्राप्त हो रहा है

मैंने कोशिश की है चीजें

  • प्राथमिक के रूप में सेम में से एक बनाने की कोशिश की है
  • पर्सिस्टेंस कॉन्टैक्ट का इस्तेमाल किया है, जैसा कि नीचे कोड में देखा जा सकता है।

मेरा अपवाद ट्रेस

मेरा ऑर्डर नियंत्रक जो बस रोटॉजिटरी का संचालन करता है

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

    @Autowired
    private OrderRepository nextGenorder;

मेरा ऑर्डर रिपोजिटरी है

@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;
    }

मेरी फर्स्ट कॉनफिग फाइल

@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();
    }

}

और दूसरा विन्यास

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.mymerkbiotech.blueberry.crud.repository.running", entityManagerFactoryRef = "mymerkLimsEntityManagerFactory", transactionManagerRef = "transactionManagertwo")

    @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;
    }

}

मैंने दृढ़ता से अनभिज्ञनबीन पोस्ट प्रोससेसर में डीबगिंग करने की कोशिश की लेकिन वह जल्द ही खो गया।


मुझे लगता है कि आपको अपने स्थानीय कंटैनेयरएन्टीटीएमएनेजरफिचरबेन के दोनों विन्यास में नाम देना चाहिए। तो ऐसा दिखना चाहिए:

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

पहले के लिए और

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

दूसरे के लिए
