    <artifactId>bytetcc-supports-springcloud</artifactId>
    <version>0.5.7</version>
</dependency>
1.1.2. dubbo
<dependency>
    <groupId>org.bytesoft</groupId>
    <artifactId>bytetcc-supports-dubbo</artifactId>
    <version>0.5.7</version>
</dependency>

1.2 Compose a business service

@Service("accountService")
@Compensable(
  interfaceClass = IAccountService.class 
, confirmableKey = "accountServiceConfirm"
, cancellableKey = "accountServiceCancel"
)
public class AccountServiceImpl implements IAccountService {

    @Resource(name = "jdbcTemplate")
    private JdbcTemplate jdbcTemplate;

    @Transactional
    public void increaseAmount(String accountId, double amount) throws ServiceException {
        this.jdbcTemplate.update("update tb_account set frozen = frozen + ? where acct_id = ?", amount, acctId);
    }

}

1.3 Compose a confirm service

@Service("accountServiceConfirm")
public class AccountServiceConfirm implements IAccountService {

    @Resource(name = "jdbcTemplate")
    private JdbcTemplate jdbcTemplate;

    @Transactional
    public void increaseAmount(String accountId, double amount) throws ServiceException {
        this.jdbcTemplate.update("update tb_account set amount = amount + ?, frozen = frozen - ? where acct_id = ?", amount, amount, acctId);
    }

}

1.4 Compose a cancel service

@Service("accountServiceCancel")
public class AccountServiceCancel implements IAccountService {

    @Resource(name = "jdbcTemplate")
    private JdbcTemplate jdbcTemplate;

    @Transactional
    public void increaseAmount(String accountId, double amount) throws ServiceException {
        this.jdbcTemplate.update("update tb_account set frozen = frozen - ? where acct_id = ?", amount, acctId);
    }
