ByteTCC是一个基于TCC(Try/Confirm/Cancel)机制的分布式事务管理器。兼容JTA,可以很好的与Spring容器进行集成。

@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); } }
@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); } }
@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); } }
任意时刻 因 任意故障 (包括但不限于:业务系统/RDBS服务器宕机;网络故障;断电等)造成的事务中断,ByteTCC均有相应机制予以恢复,保证全局事务的最终一致性。
ByteTCC 在框架层面提供对Confirm/Cancel业务逻辑的幂等性保障 ,业务系统仅需关注自身业务本身,无需为幂等性问题而烦恼。
