服务端搭建 docker-compose编排服务 version: '3' seata-server: image: seataio/seata-server:1.5.1 container_name: seata-server ports: - "7091:7091" - "8091:8091" environment: - TZ=Asia/Shanghai - SEATA_IP=IP地址(注意这里要填可以访问的ip) - SEATA_PORT=8091 volumes: # 配置文件目录映射 - /docker/seata/config/application.yml:/seata-server/resources/application.yml application.yml 配置文件 server: port: 7091 spring: application: name: seata-server logging: config: classpath:logback-spring.xml file: path: ./logs/seata # extend: # logstash-appender: # destination: 127.0.0.1:4560 # kafka-appender: # bootstrap-servers: 127.0.0.1:9092 # topic: logback_to_logstash console: user: username: seata password: seata seata: config: # support: nacos 、 consul 、 apollo 、 zk 、 etcd3 type: nacos nacos: # nacos ip地址 server-addr: 127.0.0.1:8848 group: DEFAULT_GROUP namespace: username: password: ##if use MSE Nacos with auth, mutex with username/password attribute #access-key: "" #secret-key: "" # 读取nacos上的配置文件 data-id: seata-server.properties registry: # support: nacos 、 eureka 、 redis 、 zk 、 consul 、 etcd3 、 sofa type: nacos nacos: application: seata-server # nacos ip地址 server-addr: 127.0.0.1:8848 group: DEFAULT_GROUP namespace: cluster: default username: password: ##if use MSE Nacos with auth, mutex with username/password attribute #access-key: "" #secret-key: "" security: secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017 tokenValidityInMilliseconds: 1800000 ignore: urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login seata-server.properties 配置文件

再nacos创建 seata-server.properties 配置文件修改其中的 mysql 连接地址

访问 7091 端口进入seata 控制台查看 nacos 服务注册列表

客户端搭建 pom依赖

由于 SpringCloud Alibaba seata 使用的客户端为 1.4.2 故排除依赖手动引入 1.5.X

在 nacos 创建 seata-client-demo.yml 配置文件用于编写客户端 seata 配置

# seata配置 seata: enabled: true application-id: seata-cilent-deme # Seata 事务组编号，此处需于 seata 相同 tx-service-group: default-tx-group config: type: nacos nacos: # nacos ip地址 server-addr: 127.0.0.1:8848 group: DEFAULT_GROUP data-id: seata-server.properties # 读取 nacos seata 配置 registry: type: nacos nacos: application: seata-server # seata 服务名 # nacos ip地址 server-addr: 127.0.0.1:8848 group: DEFAULT_GROUP 数据库配置

在客户端连接的业务数据库增加 undo_log 表

-- 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` ( `branch_id` BIGINT(20) NOT NULL COMMENT 'branch transaction id', `xid` VARCHAR(100) 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'; 代码编写

最初调用方为事务发起者需标记 seata 注解

@GlobalTransactional(rollbackFor = Exception.class)
