准备

在本机新建数据库fescar_demo，并修改jdbc.properties里的三处用户名、密码。

使用seata-samples\dubbo\src\main\resources\sql下的SQL脚本，新建表：undo_log、storage_tbl、order_tbl、account_tbl。
为了方便观察数据，新建表undo_log_my，语句与undo_log相同。新建触发器，插入undo_log表后，将内容copy一份再插入undo_log_my：

CREATE TRIGGER copy_undo_log
AFTER INSERT ON undo_log
FOR EACH ROW
INSERT INTO undo_log_my
VALUES (NEW.id, NEW.branch_id, NEW.xid, NEW.context, NEW.rollback_info, NEW.log_status, NEW.log_created, NEW.log_modified, NEW.ext);

修改log4j.properties为：

log4j.rootLogger = debug,stdout### output console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%nlog4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

在本地安装Zookeeper，网上的资料有很多，此处略。通过命令行执行：D:\ProgramFiles\zookeeper-3.4.6\bin\zkServer.cmd

修改4处的Dubbo配置：

    <!--<dubbo:registry address="multicast://127.0.0.1:1234?unicast=false" />--><!--support etcd --><!--<dubbo:registry address="etcd3://127.0.0.1:2379/org.apache.dubbo.registry.RegistryService" />--><!--support zk--><dubbo:registry address="zookeeper://localhost:2181" /><!--support nacos--><!--<dubbo:registry address="nacos://127.0.0.1:8848"/>-->

seata-samples\dubbo模块依赖了seata-all 0.8.0 版本，下载相应版本的seata-server-0.8.0.zip，通过命令行执行：D:\ThirdPartiesFiles\seata\seata-server-0.8.0\bin\seata-server.bat

模拟正常的业务流程

注释掉seata-samples\dubbo\src\main\java\io\seata\samples\dubbo\service\BusinessServiceImpl.java里的运行期异常：

    @Override@GlobalTransactional(timeoutMills = 300000, name = "dubbo-demo-tx")public void purchase(String userId, String commodityCode, int orderCount) {LOGGER.info("purchase begin ... xid: " + RootContext.getXID());storageService.deduct(commodityCode, orderCount);orderService.create(userId, commodityCode, orderCount);//throw new RuntimeException("xxx");}

启动账户服务 (DubboAccountServiceStarter)，account_tbl表里被程序插入一条记录。

user_id	money
U100001	999

启动库存服务 (DubboStorageServiceStarter)，storage_tbl表里被程序插入一条记录。

commodity_code	count
C00321	100

启动订单服务 (DubboOrderServiceStarter)，order_tbl表里暂无记录。

运行BusinessService入口 (DubboBusinessTester)，模拟业务逻辑：用户U100001购买了2件编号为C00321的商品，单价￥200（是硬编码），合计￥400。order_tbl表里被程序插入一条记录：

user_id	commodity_code	count	monty
U100001	C00321	2	400

同时，account_tbl表被扣减400元：

user_id	money
U100001	599

storage_tbl表被扣减2件库存：

commodity_code	count
C00321	98

undo_log表里似乎没有记录？！其实是先被插入，后又被删除了。还好，我们定义了触发器，把插入到undo_log表里的数据拷贝一份到undo_log_my表。
id为1、2、3行的rollback_info列内容分别如下：

xid：全局事务ID。
branchId：分支事务ID，上例中，模拟了3个分支事务，即帐户事务、库存事务和订单事务。
beforeImage：全局事务开启前，某表的数据镜像。
afterImage：全局事务提交后，某表的数据镜像。

模拟异常业务流程

停止seata-server-0.8.0（方便观察日志），停止上述三个服务，把所有表记录清空后，去掉那行注释，再依次启动seata-server-0.8.0和上述三个服务。
运行BusinessService入口 (DubboBusinessTester)，由于在最后遇到了运行期异常，所有分支事务都回滚了。可以查看表记录进行验证。

在三个IP上，分别建库和表，正常、异常流程均可以运行。

IP/库名	表
jdbc:mysql://localhost:3306/fescar_demo	account_tbl、undo_log
