Calling method that marked @Transactional (propagation=Propagation.REQUIRES_NEW)

[mkhafizov]

Hello, everyone!

There are two classes:

@Component
public class A {
  @Autowired
  private B b;

  @Autowired
  private DefaultJdbcTemplate jdbcTemplate;
  
  @Transactional
  public void doA() {
    System.out.println("1. txid: " + jdbcTemplate.queryForObject("select txid_current()", String.class));
    b.doB();
    System.out.println("3. txid: " + jdbcTemplate.queryForObject("select txid_current()", String.class));
  }

}

@Component
public class B
{
  @Autowired
  private DefaultJdbcTemplate jdbcTemplate;
  

  @Transactional(propagation=Propagation.REQUIRES_NEW)
  public void doB()
  {
     System.out.println("2. txid: " + jdbcTemplate.queryForObject("select txid_current()", String.class));
  }
  
}

Output:

1. txid: 42714642
2. txid: 42714669
3. txid: 42714677

Statements #1 and #3 are executed in different transactions. Is that a normal behavior? I'm using postgres and JtaTransactionManager.

Thanks.
