Java17 --- SpringCloud之seate

一、创建seata需要的mysql数据库表

二、修改seata的配置文件

三、启动nacos及seata

四、创建需要的数据库及表

二、修改seata的配置文件

三、启动nacos及seata

四、创建需要的数据库及表

CREATE DATABASE seata_order;

USE seata_order;

 

CREATE TABLE t_order(

`id` BIGINT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,

`user_id` BIGINT(11) DEFAULT NULL COMMENT '用户id',

`count` INT(11) DEFAULT NULL COMMENT '数量',

`money` DECIMAL(11,0) DEFAULT NULL COMMENT '金额',

`status` INT(1) DEFAULT NULL COMMENT '订单状态: 0:创建中; 1:已完结'

)ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

 

SELECT * FROM t_order;



-- for AT mode you must to init this sql for you business database. the seata server not need it.

CREATE TABLE IF NOT EXISTS `undo_log`
