seata-springboot整合笔记

添加依赖<dependency> <groupId>io.seata</groupId> <artifactId>seata-spring-boot-starter</artifactId> </dependency> 建表CREATE TABLE undo_log( id BIGINT(20) NOT NULL AUTO_INCREMENT PRIMARY KEY, 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, UNIQUE KEY ux_undo_log(xid,branch_id) ) ENGINE = INNODB DEFAULT CHARSET = utf8; 修改application.properties配置,从源码包中复制即可

seata源码中/seata-1.3.0/script/client/spring/application.properties中有效内容复制粘贴

配置主要关注项seata.enabled=true seata.application-id=${spring.application.name} # 与服务端配置的保持一致即可，服务端为每个微服务添加对应的配置 # 对应服务端配置: service.vgroupMapping.sample_account_service_tx_group=default seata.tx-service-group=sample_account_service_tx_group # 这里配置微服务对应的undo表名称 seata.client.undo.log-table=undo_log # 注意这里与上面的seata.tx-service-group配置一定要对应上 seata.service.vgroup-mapping.sample_account_service_tx_group=default seata.service.grouplist.default=192.168.221.128:8091 # config与registry与服务端保持一致即可 seata.config.type=nacos seata.config.nacos.namespace= seata.config.nacos.serverAddr=192.168.221.128:8848 seata.config.nacos.group=SEATA_GROUP seata.registry.type=nacos seata.registry.nacos.application=seata-server seata.registry.nacos.server-addr=192.168.221.128:8848 seata.registry.nacos.group=SEATA_GROUP seata.registry.nacos.namespace= 在服务调用的最外层添加@GlobalTransactional注解public class RestOrderServiceImpl implements IRestOrderService { @Reference(version = "1.0.1", group = "yicj") private IRepoService repoService; @Reference(version = "1.0.1", group = "yicj") private IOrderService orderService; @GlobalTransactional(timeoutMills = 30000, name = "sample-rest-web") @Override public ObjectResponse handleBusiness(OrderRequest orderRequest) throws Exception { log.info("开始全局事务: xid = {}", RootContext.getXID()); log.info("begin order: "+orderRequest); } } 在每微服务应用中可获取事务xidString xid = RootContext.getXID() ; log.info("开始全局事务: xid = {}", xid);
