seata的使用（SpringBoot项目整合seata）

1、解压 seata-server-1.7.1.zip

2、启动 双击 seata-server.bat

Active code page: 65001
"E:\seata-server-1.7.1\seata/logs"
"apm-skywalking not enabled"
[0.042s][warning][gc] -Xloggc is deprecated. Will use -Xlog:gc:E:\seata-server-1.7.1\seata/logs/seata_gc.log instead.

3、启动 seata 控制台用户界面

you can visit seata console UI on http://127.0.0.1:7091

4、所有分布式事务相关数据库要有undo-log

seata快速开始：https://seata.apache.org/zh-cn/docs/user/quickstart/

CREATE TABLE IF NOT EXISTS `undo_log`
(`branch_id`     BIGINT       NOT NULL COMMENT 'branch transaction id',`xid`           VARCHAR(128) NOT NULL COMMENT 'global transaction id',`context`       VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',`rollback_info` LONGBLOB     NOT NULL COMMENT 'rollback info',`log_status`    INT(11)      NOT NULL COMMENT '0:normal status,1:defense status',`log_created`   DATETIME(6)  NOT NULL COMMENT 'create datetime',`log_modified`  DATETIME(6)  NOT NULL COMMENT 'modify datetime',UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)) ENGINE = InnoDB AUTO_INCREMENT = 1 DEFAULT CHARSET = utf8mb4 COMMENT ='AT transaction mode undo table';
ALTER TABLE `undo_log` ADD INDEX `ix_log_created` (`log_created`);

5、项目引入seata依赖

        <dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-seata</artifactId></dependency><dependency><groupId>io.seata</groupId><artifactId>seata-spring-boot-starter</artifactId></dependency>

6、项目添加seata配置

seata: tx-service-group: guli_tx_groupservice:vgroup-mapping:guli_tx_group: defaultgrouplist:default: localhost:8091

7、代码实现：
