记录基于seata官网本地搭建seata的过程
下载seata软件报(Releases · seata/seata · GitHub)将其解压缩。
启动seata服务
sh seata-server.sh -p 8091 -h 127.0.0.1 -m file
下载官网提供的示例(GitHub - seata/seata-samples: seata-samples)
如果使用zk为注册中心，本地首先要启动zk服务，然后分别修改下面四个配置文件的注册中心为zk
新建一个seata库，并在表中初始化如下五张表的结构
-- 注意此处0.3.0+ 增加唯一索引 ux_undo_log
CREATE TABLE `undo_log`
(
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`branch_id` bigint(20) NOT NULL,
`xid` varchar(100) NOT NULL,
`context` varchar(128) NOT NULL,
`rollback_info` longblob NOT NULL,
`log_status` int(11) NOT NULL,
`log_created` datetime NOT NULL,
`log_modified` datetime NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `stock_tbl`;
CREATE TABLE `stock_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;
分别启动：
1、DubboAccountServiceStarter；
2、DubboStorageServiceStarter；
3、DubboOrderServiceStarter
然后再运行DubboBusinessTester就可以看到测试效果了
Remark：运行demo时遇到的问题
1、报如下错误是因为spring和com.alibaba.spring版本兼容性问题，需要加一个version

解决方案 加一个
2、由于我本地数据库使用的mysql8，因此需要做如下修改
修改驱动
jdbc.stock.driver=com.mysql.cj.jdbc.Driver
修改pom中的依赖为
