开源软件介绍：

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EJB、Spring等容器（本文档下文说明中将以Spring容器为例）进行集成。

一、快速入门

1.1. 加入maven依赖

1.1.1. 使用Spring Cloud

<dependency>	<groupId>org.bytesoft</groupId>	<artifactId>bytetcc-supports-springcloud</artifactId>	<version>0.5.10</version></dependency>

1.1.2. 使用dubbo

<dependency>	<groupId>org.bytesoft</groupId>	<artifactId>bytetcc-supports-dubbo</artifactId>	<version>0.5.10</version></dependency>

1.2. 编写业务服务

@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. 编写confirm服务

@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. 编写cancel服务

@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);	}}
