在jeecg-order库中，创建表
CREATE TABLE `orders` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) DEFAULT NULL,
`product_id` int(11) DEFAULT NULL,
`pay_amount` int(11) DEFAULT NULL,
`add_time` datetime DEFAULT NULL,
`update_time` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=50 DEFAULT CHARSET=utf8mb4;
在jeecg-product中，创建表并插入数据
CREATE TABLE `product` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`price` int(11) DEFAULT NULL,
`stock` int(11) DEFAULT NULL,
`add_time` datetime DEFAULT NULL,
`update_time` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4;
INSERT INTO `product` (`id`, `name`, `price`, `stock`, `add_time`, `update_time`) VALUES ('1', '电池', '10', '67', '2021-01-15 00:00:32', '2021-01-15 00:00:35');

5. Seata启动
采用jeecg-boot单体模式测试，使用默认的文件进行seata配置，不需要做额外的配置，直接启动seata-server.bat即可。

在浏览器请求
http://localhost:8080/jeecg-boot/order?userId=1&productId=1
正常提交，数据库数据都是正常的。
http://localhost:8080/jeecg-boot/order?userId=2&productId=1
更新异常，数据回滚。
