# Fescar Example
## 项目说明
本项目演示如何使用 Fescar Starter 完成 Spring Cloud 应用的分布式事务接入。
[Fescar](https://github.com/alibaba/fescar) 是 阿里巴巴 开源的 分布式事务中间件，以 高效 并且对业务 0 侵入 的方式，解决 微服务 场景下面临的分布式事务问题。
## 准备工作
在运行此示例之前，你需要先完成如下几步准备工作：
1. 配置数据库
1. Create UNDO_LOG table
1. Create tables for examples business
1. Start Fescar Server
### 配置数据库
首先，你需要有一个支持 InnoDB 引擎的 MySQL 数据库。
**注意**： 实际上，Fescar 支持不同的应用使用完全不相干的数据库，但是这里为了简单地演示一个原理，所以我们选择了只使用一个数据库。
将 `account-server`、`order-service`、`storage-service` 这三个应用中的 resources 目录下的 `application.properties` 文件中的如下配置修改成你运行环境中的实际配置。
```
mysql.server.ip=your mysql server ip address
mysql.server.port=your mysql server listening port
mysql.db.name=your database name for test
mysql.user.name=your mysql server username
mysql.user.password=your mysql server password
```
### 创建 UNDO_LOG 表
[Fescar AT 模式]() 需要使用到 UNDO_LOG 表。
``` $sql
CREATE TABLE `undo_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`branch_id` bigint(20) NOT NULL,
`xid` varchar(100) NOT NULL,
`rollback_info` longblob NOT NULL,
`log_status` int(11) NOT NULL,
`log_created` datetime NOT NULL,
`log_modified` datetime NOT NULL,
`ext` varchar(100) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `idx_unionkey` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=159 DEFAULT CHARSET=utf8
```
### 创建 示例中 业务所需要的数据库表
```$sql
DROP TABLE IF EXISTS `storage_tbl`;
CREATE TABLE `storage_tbl` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`commodity_code` varchar(255) DEFAULT NULL,
`count` int(11) DEFAULT 0,
PRIMARY KEY (`id`),
UNIQUE KEY (`commodity_code`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `order_tbl`;
CREATE TABLE `order_tbl` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` varchar(255) DEFAULT NULL,
`commodity_code` varchar(255) DEFAULT NULL,
`count` int(11) DEFAULT 0,
`money` int(11) DEFAULT 0,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `account_tbl`;
CREATE TABLE `account_tbl` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` varchar(255) DEFAULT NULL,
`money` int(11) DEFAULT 0,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
```
### 启动 Fescar Server
点击这个页面 [https://github.com/alibaba/fescar/releases](https://github.com/alibaba/fescar/releases)，下载最新版本的 Fescar Server 端.
进入解压之后的 bin 目录，执行如下命令来启动
```$shell
sh fescar-server.sh $LISTEN_PORT $PATH_FOR_PERSISTENT_DATA
```
在这个示例中，采用如下命令来启动 Fescar Server
```$shell
sh fescar-server.sh 8091 ~/fescar/data/
```
**注意** 如果你修改了端口号，那么记得需要在各个示例工程中的 `application.conf` 文件中，修改 grouplist 的值。
## 运行示例
分别运行 `account-server`、`order-service`、`storage-service` 和 `business-service` 这三个应用的 Main 函数，启动示例。
启动示例后，通过 HTTP 的 GET 方法访问如下两个 URL，可以分别验证在 `business-service` 中 通过 RestTemplate 和 FeignClient 调用其他服务的场景。
```$xslt
http://127.0.0.1:18081/fescar/feign
http://127.0.0.1:18081/fescar/rest
```
## 如何验证分布式事务成功？
### Xid 信息是否成功传递
在 `account-server`、`order-service` 和 `storage-service` 三个 服务的 Controller 中，第一个执行的逻辑都是输出 RootContext 中的 Xid 信息，如果看到都输出了正确的 Xid 信息，即每次都发生变化，且同一次调用中所有服务的 Xid 都一致。则表明 Fescar 的 Xid 的传递和还原是正常的。
### 数据库中数据是否一致
在本示例中，我们模拟了一个用户购买货物的场景，StorageService 负责扣减库存数量，OrderService 负责保存订单，AccountService 负责扣减用户账户余额。
为了演示样例，我们在 OrderService 和 AccountService 中 使用 Random.nextBoolean() 的方式来随机抛出异常,模拟了在服务调用时随机发生异常的场景。
如果分布式事务生效的话， 那么以下等式应该成立
- 用户原始金额(1000) = 用户现存的金额 + 货物单价 (2) * 订单数量 * 每单的货物数量(2)
- 货物的初始数量(100) = 货物的现存数量 + 订单数量 * 每单的货物数量(2)
## 对 Spring Cloud 支持点
- 通过 Spring MVC 提供服务的服务提供者，在收到 header 中含有 Fescar 信息的 HTTP 请求时，可以自动还原 Fescar 上下文。
- 支持服务调用者通过 RestTemplate 调用时，自动传递 Fescar 上下文。
- 支持服务调用者通过 FeignClient 调用时，自动传递 Fescar 上下文。
- 支持 FeignClient 和 Hystrix 同时使用的场景。
- 支持 FeignClient 和 Sentinel 同时使用的场景。
