wangxusheng258813 commented on issue #583: Failed to get reconnected sender, all alpha server is down. URL: https://github.com/apache/servicecomb-pack/issues/583#issuecomment-549723480 之前的情况： 在服务A的controller加上@SagaStart 在服务A中用到的service加了@Compensable(compensationMethod = "cancel")。 在服务B用到的service加上@Compensable(compensationMethod = "cancel")。 执行就报上述错误 Failed to get reconnected sender, all alpha server is down. 刚才试了这种情况： 在服务A的controller加上@SagaStart 在服务A中用到的service加了@Compensable(compensationMethod = "cancel")。 在服务B的controller（被服务A使用Feign调用的所有controller方法）加上@SagaStart 用到的service加上@Compensable(compensationMethod = "cancel")。这样正常调用能成功。 如果B中其中一个service出现了异常 A中的子事务执行了cancel B中的子事务却未执行cancel
