README

        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

```xml

	org.bytesoft

	bytetcc-supports-springcloud

	0.5.12

```

###### 1.1.2. 使用dubbo

```xml

	org.bytesoft

	bytetcc-supports-dubbo

	0.5.12

```

#### 1.2. 编写业务服务

```java

@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

```java

@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

```java

@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);

	}

}

```
