在Seata执行过程中遇到“Failed to get available servers: service.vgroupMapping.law-firm-group configuration item is required”错误,这个错误提示表明Seata客户端在启动时无法从配置中找到名为law-firm-group的虚拟组服务映射配置。 Seata通过服务分组(vgroup)来管理不同的分布式事务协调者(TC)集群。在Seata配置文件...

所以我们直接通过官方案例引入的Seata包,找到SpringBoot项目在启动的时候自动扫描加载类型的spring.factories,然后找到GlobalTransactionAutoConfiguration(Seata自动配置类) 2.全局事务扫描类源码 这个类型的核心点,就是加载配置,注入相关的Bean /** * seata自动配置类 ...
