@Autowired not working for a repository

[Alejandro Barrero]

In a class I have

public class JpaRepository1 {
	@Autowired
	private BankRepository bankRepository;

	public static void main(String[] args) {
		JpaRepository1 jpaRepository1 = new JpaRepository1();
		jpaRepository1.saveInDB();
	}
	
	private void saveInDB() {
		Bank bank = createBank("Bank1");	
		bankRepository.saveAndFlush(bank);
	}

When running I get  bankRepository null.
I have

@Transactional
@Repository
public interface BankRepository extends JpaRepository<Bank, Long> {

}

@Configuration
@EnableTransactionManagement
@ComponentScan("com")
@PropertySource("classpath:persistence-mysql.properties")
@EnableJpaRepositories(basePackages = "com")
public class PersistenceJPAConfig {

That is because your class JpaRepository1 is not a Spring bean, and you are instantiating the class yourself using new JpaRepository1() in line 6 instead of letting Spring manage it.

Spring autowiring only works in Spring beans. Spring cannot autowire fields in objects that are not Spring beans.

Thank you for your help. I tried to use your ideas, but it still doesn't work (well I am just learning).
This is what I did

public class JpaRepository1 {
	public static void main(String[] args) {
		BankService bankService = new BankService();
		Bank bank = createBank("Test Bank");
		bankService.saveInDB(bank);
	}

@Configuration
@EnableTransactionManagement
@ComponentScan("com")
@PropertySource("classpath:persistence-mysql.properties")
@EnableJpaRepositories(basePackages = "com")
public class PersistenceJPAConfig {
	@Bean
	public BankService getBankService() {
		return new BankService();
	}

public class BankService {
	@Autowired
	private BankRepository bankRepository;
	
	public void saveInDB(Bank bank) {
		bankRepository.saveAndFlush(bank);
	}

@Transactional
@Repository
public interface BankRepository extends JpaRepository<Bank, Long> {

}

I also tried to inject BankService in JpaRepository1 but it didn't work.
