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);
}
}
```
