1.2 nacos（采用db模式）

这里不做讲解

2.软件配置：

2.1 准备工作nacos得配置好

2.1.1 先把nacos起起来

在这里插入图片描述

2.1.2配置seata：先看长啥样

在这里插入图片描述

2.1.2配置seata的 application.yml（主要是配置中心和注册中心）

在这里插入图片描述

2.1.3 配置好如图：

2.1.4 在nacos中配置 seataServer.properties的相关配置内容,该配置存在位置如下图：

2.1.5配置好如下图，具体seataServer.properties：

2.1.6需要的sql（绿色为业务库）：

在这里插入图片描述

2.1.6.1自身框架库需要的sql（4张表 ，1.5以前不知道三张表就行）：

CREATE TABLE `branch_table` (`branch_id` bigint(20) NOT NULL,`xid` varchar(128) NOT NULL,`transaction_id` bigint(20) DEFAULT NULL,`resource_group_id` varchar(32) DEFAULT NULL,`resource_id` varchar(256) DEFAULT NULL,`branch_type` varchar(8) DEFAULT NULL,`status` tinyint(4) DEFAULT NULL,`client_id` varchar(64) DEFAULT NULL,`application_data` varchar(2000) DEFAULT NULL,`gmt_create` datetime(6) DEFAULT NULL,`gmt_modified` datetime(6) DEFAULT NULL,PRIMARY KEY (`branch_id`) USING BTREE,KEY `idx_xid` (`xid`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;CREATE TABLE `distributed_lock` (`lock_key` char(20) NOT NULL,`lock_value` varchar(20) NOT NULL,`expire` bigint(20) DEFAULT NULL,PRIMARY KEY (`lock_key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;CREATE TABLE `global_table` (`xid` varchar(128) NOT NULL,`transaction_id` bigint(20) DEFAULT NULL,`status` tinyint(4) NOT NULL,`application_id` varchar(32) DEFAULT NULL,`transaction_service_group` varchar(32) DEFAULT NULL,`transaction_name` varchar(128) DEFAULT NULL,`timeout` int(11) DEFAULT NULL,`begin_time` bigint(20) DEFAULT NULL,`application_data` varchar(2000) DEFAULT NULL,`gmt_create` datetime DEFAULT NULL,`gmt_modified` datetime DEFAULT NULL,PRIMARY KEY (`xid`) USING BTREE,KEY `idx_gmt_modified_status` (`gmt_modified`,`status`) USING BTREE,KEY `idx_transaction_id` (`transaction_id`) USING BTREE

) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;

2.1.6.2业务库需要的sql（每个业务库都要有）：

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,`ext` varchar(100) DEFAULT NULL,PRIMARY KEY (`id`) USING BTREE,UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;

2.1.6.3自己写的 java代码业务库需要的sql：

seata-count库

CREATE TABLE `tb_account` (`id` int(11) NOT NULL AUTO_INCREMENT,`user_id` varchar(255) DEFAULT NULL,`money` int(11) unsigned DEFAULT '0',PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;
CREATE TABLE `tb_account_freeze` (`xid` varchar(50) NOT NULL,`user_id` int(20) DEFAULT NULL,`freeze_money` int(20) DEFAULT NULL,`state` varchar(20) DEFAULT NULL,PRIMARY KEY (`xid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

seata-order库

CREATE TABLE `tb_order` (`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',`create_time` datetime DEFAULT NULL,PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;

seata-storage库

CREATE TABLE `tb_storage` (`id` int(11) NOT NULL AUTO_INCREMENT,`commodity_code` varchar(255) DEFAULT NULL,`count` int(11) unsigned DEFAULT '0',PRIMARY KEY (`id`) USING BTREE,UNIQUE KEY `commodity_code` (`commodity_code`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;

windows 下cmd命令窗口执行测试也行，具体测试数据自己造叭。

curl --location --request POST 'localhost:7001/order' \
--header 'Content-Type: application/json' \
--header 'Cookie: Cookie_1=value' \
--data-raw '{"userId":123,"commodityCode":"100202003032041","count":1,"money":2
