User-defined bean method 'entityManagerFactory

Question

I am developing Spring Boot Batch Example. In this example, I have created BatchJPA core module which has Entities, JPARepository and DB configurations.

This module adding into another Spring Module as dependency and in this module, I am adding code related specific batch jobs (like custom repository etc). I have total 15 batch jobs and I will be creating separate Spring Boot project with BatchJPA dependency.

Now I am getting below error:

10-08-2018 20:13:10.122 [main] WARN  org.springframework.context.support.ClassPathXmlApplicationContext.refresh - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'CustMstrCustomRepository': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available

Description:

A component required a bean of type 'javax.persistence.EntityManagerFactory' that could not be found.
    - User-defined bean method 'entityManagerFactory' in 'CommonDatabaseConfig'


Action:

Consider revisiting the entries above or defining a bean of type 'javax.persistence.EntityManagerFactory' in your configuration.

CommonDatabaseConfig.java

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.XXXXX.ABC.repository", 
                    entityManagerFactoryRef = "entityManagerFactory", 
                    transactionManagerRef = "transactionManager")
public class CommonDatabaseConfig {
    // This is needed
    @Bean
    @Primary
    @ConfigurationProperties("ABC.datasource")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Primary
    @Bean(name = "dataSource")
    @ConfigurationProperties(prefix = "ABC.datasource")
    public DataSource dataSource() {
        return dataSourceProperties().initializeDataSourceBuilder().build();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource) {
        return builder
                .dataSource(dataSource)
                .packages("com.XXXXX.ABC.Entity")
                .persistenceUnit("MyDBDev")
                .build();
    }

    @Primary
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(@Qualifier("entityManagerFactory") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }

    @Bean
    public PersistenceAnnotationBeanPostProcessor beanPostProcessor() {
        return new PersistenceAnnotationBeanPostProcessor();
    }
}

DataTasklet.java

@Service
@Qualifier("DataTasklet")

    // TODO - Here I am getting null - unable to create @Bean here 
    @Autowired
    private CustMstrCustomRepository custMstrCustomRepository;

    @Override
    public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {

        List<CustomCustomEntity> data = CustMstrCustomRepository.getData();

        chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext().put("data", data);

        return RepeatStatus.FINISHED;
    }
}

CustMstrCustomRepository.java

@Configuration
@Service
public class CustMstrCustomRepository {

    private static final String SQL= "MY COMPEX JOIN QUERY HERE - ";

    @PersistenceContext
    @Qualifier(value = "entityManagerFactory")
    private EntityManager entityManager;

    @SuppressWarnings("unchecked")
    public List<CustomCustomEntity> getData()() {
        Query q = entityManager.createNativeQuery(SQL);
        q.setParameter("isActv", "Y");

        List<Object[]> resultList = q.getResultList();

        List<CustomCustomEntity> results = new ArrayList<>();
        for (Object[] objects : resultList) {
            results.add(CustomCustomEntity.builder()
                    .XX((BigDecimal) objects[0])
                    .YY((BigDecimal) objects[1])
                    .ZZ((Date) objects[2])
                    .AA((Date) objects[3])
                    .BB((String) objects[4]).build());           
        }
        return results;
    }
}

MainApplication.java

@SpringBootApplication
@EnableBatchProcessing
public class MainApplication implements CommandLineRunner {

    @Autowired
    private DataBatchJobLauncher jobLauncher;

    @Bean
    public Tasklet dataTasklet() {
        return new DataTasklet();
    }

    public static void main(String[] args) {
        SpringApplication.run(EdsMainApplication.class, args);
    }

    @Override
