I have put @Transactional in method still it commits the transaction before rollback

Question

How to achieve transaction management in Spring

My methods are as below

@Transactional(rollbackFor = RuntimeException.class, propagation = Propagation.REQUIRED)
@Override
public InwardDTO saveEntity(InwardDTO entity) throws Exception {
    try {
        costCalculation(entity);
        InwardDTO dto = super.saveEntity(entity);
        addStock(dto.getDetails(), dto.getId());
        return dto;
    } catch (Exception ex) {
        throw ex;
    }
}

private void addStock(Set<InwardDetailsDTO> argDetailsDTOSet, Long argInwardId) throws RuntimeException {
    String SUBMODULE = getModuleNameForLog() + " [addStock()] ";

    if (1 == 1) {
        throw new RuntimeException("Test Case");
    }
}

Logs are like,

In this transactional is always commited before rollback of addStock Method ... In logs it is showing like transaction is rollback but entry is saved in DB...

Answer 1

In case the table storage engine is MyISAM: This engine does not support transactions. The correct one should be InnoDB.

If you are using automatic creation of tables from Hibernate: I would recommend writing your own migrations and using tool like Flyway do manage those. It's a bit more work but you will have total control over how your tables look like.

Answer 2

Spring transaction bean required list:

1.JdbcTemplate

@Bean(name = "jdbcTemplate")
public JdbcTemplate creatJdbcTemplate(@Qualifier("dataSource") DataSource dataSource) {
    return new JdbcTemplate(dataSource);
}

2.DataSource

@Bean(name = "dataSource")
public DataSource creatDataSource() {
    DriverManagerDataSource ds = new DriverManagerDataSource();
    ds.setDriverClassName(driverClassName);
    ds.setUrl(url);
    ds.setUsername(username);
    ds.setPassword(password);
    return ds;
}

3.TransactionManager

@Bean(name = "transactionManager")
public PlatformTransactionManager creatTransactionManager(DataSource  dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

4.@EnableTransactionManagement above one @Configuration Class to activate TxManager

5.Use JdbcTemplate's instance(@Autowired) in DaoImplements to execute sql with query() || update() method
