官网源码地址：https://github.com/seata/seata

网上许多搭建版本趋向于老版本，故自己参考官网 http://seata.io/en-us/ 和其他搭建方法总结出一套完整说明，故记录一哈

 

环境搭建 Seata+Nacos+Springcloud Alibaba

Server配置：

..\seata\conf 目录下

配置：file.conf

 

配置：registry.conf

 

服务端及配置完成，接下来是创建对应数据库

..\seata-develop\script\server\db 目录下根据对应的数据库执行对应的sql文件

先创建数据库或者导入已经使用的数据库，但是需要跟file.conf配置的数据库名字对应即可

 

需要在所有服务数据库下创建回滚日志表

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for undo_log
-- ----------------------------
DROP TABLE IF EXISTS `undo_log`;
CREATE TABLE `undo_log`  (
  `id` bigint(0) NOT NULL AUTO_INCREMENT,
  `branch_id` bigint(0) NOT NULL,
  `xid` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `context` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `rollback_info` longblob NOT NULL,
  `log_status` int(0) NOT NULL,
  `log_created` datetime(0) NOT NULL,
  `log_modified` datetime(0) NOT NULL,
  `ext` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE,
  UNIQUE INDEX `ux_undo_log`(`xid`, `branch_id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '回滚日志表' ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of undo_log
-- ----------------------------

SET FOREIGN_KEY_CHECKS = 1;

启动顺序，启动naocs(nacos配置自行百度)

..\seata\bin目录下 执行

遇到问题一：执行日志路径错误

在bin同级创建log文件

seata-server.bat 

启动成功后访问localhost:8848/nacos (nacos默认端口)

 

出现上图表示配置成功

 

接下来配置客户端：

..\seata-develop\script\config-center 该目录下将nacos和config.txt复制到

..\seata\conf目录下

 

然后配置复制后的config.txt

然后执行复制过来的nacos文件夹下面的nacos-config.sh脚本

如果启动成功则访问nacos查看配置文件，如果出现下图列表文件，即表示配置成功

然后重新启动seata-server及执行bin目录启动脚本

到此相关配置已经配置完成

接下来配置项目

        
            com.alibaba.cloud
            spring-cloud-starter-alibaba-seata
            ${spring.cloud.alibaba.system.version}
        
        
            io.seata
            seata-spring-boot-starter
            ${seata.version}
        

 

网上很多需要引入文件配置才行，但是现在新增特性配置好 过后不需要引入文件

 

出现这个表示所有配置成功

使用方式：@GlobalTransactional
