ByteTCC is an implementation of Distributed Transaction Manager, based on Try-Confirm-Cancel (TCC) mechanism.
ByteTCC is comptible with JTA and could be seamlessly integrated with Spring and other Java containers.
1. Quick Start
1.1 Add maven depenency
1.1.1. Spring Cloud
<dependency>
<groupId>org.bytesoft</groupId>
<artifactId>bytetcc-supports-springcloud</artifactId>
<version>0.5.11</version>
</dependency>1.1.2. dubbo
<dependency>
<groupId>org.bytesoft</groupId>
<artifactId>bytetcc-supports-dubbo</artifactId>
<version>0.5.11</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);
}
