1.启动服务端
1.下载 seata-server-1.4.2
2.创建数据库

store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=50005.运行服务端
seata-server.bat -h 192.168.1.5
启动成功
2.配置微服务项目
1.引入依赖
<!-- SpringBoot Seata -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
<version>2.2.5.RELEASE</version>
<exclusions>
<exclusion>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
<version>1.4.2</version>
</dependency>2.修改微服务的配置文件
# seata配置
seata:
# 默认关闭，如需启用spring.datasource.dynami.seata需要同时开启
enabled: true
# Seata 应用编号，默认为 ${spring.application.name}
application-id: seata-server
# Seata 事务组编号，用于 TC 集群名
tx-service-group: default_tx_group
# 关闭自动代理
enable-auto-data-source-proxy: false
# 服务配置项
service:
# 虚拟组和分组的映射
vgroup-mapping:
#映射集群名称
default_tx_group: DEFAULT
registry:
type: nacos
nacos:
application: seata-server
server-addr: 127.0.0.1:8848
namespace:
username: nacos
password: nacos
group: DEFAULT_GROUP
data-source-proxy-mode: XA 2.微服务链接的数据库需要建表
-- 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';3.启动微服务
链接成功
4.测试 @GlobalTransactional 注解
/**
* 删除物业公司
*/
@RequiresPermissions("business:propertyCompany:remove")
@Log(title = "物业公司", businessType = BusinessType.DELETE)
@DeleteMapping("/{ids}")
@GlobalTransactional
public AjaxResult remove(@PathVariable Long[] ids)
{
//return toAjax(bPropertyCompanyService.deleteBPropertyCompanyByIds(ids));
List<Long> longs = Arrays.asList(ids);
for(Long id:longs){
BPropertyCompany byId = bPropertyCompanyService.getById(id);
ClosePropertyCompanyOrCommunityParam param=new ClosePropertyCompanyOrCommunityParam();
param.setId(String.valueOf(byId.getId()));
param.setType(0);
param.setPhone(byId.getPhone());
R<Map> rmap= remoteUserService.closePropertyCompanyOrCommunity(param, SecurityConstants.INNER);
if (rmap.getCode() == 500){
throw new RuntimeException(rmap.getMsg());
}
}
boolean b = bPropertyCompanyService.removeByIds(Arrays.asList(ids));
return toAjax(b);
}
