coolbeevip edited a comment on issue #562: 服用调用问题 URL: https://github.com/apache/servicecomb-pack/issues/562#issuecomment-534380731 > 是的，前提是在B->C的调用时要把 gobal_transaction_id加到http header当中，并且在C的调用方法之前能够正确的加入全局事务中。所以我想看看他的代码是怎么写的。 哦，我还真没注意这种情况，如果 A，B，C 三个服务方法的注解采用如下方式，会自动传递 globalTxId吗？ A @SagaStart B @Compensable C @Compensable 我在 @Compensable的 TransactionContextHelper 中找到如下代码 ```java protected void populateOmegaContext(OmegaContext context, TransactionContext transactionContext) { if (context.globalTxId() != null) { getLogger() .warn("The context {}'s globalTxId is not empty. Update it for globalTxId:{} and localTxId:{}", context, transactionContext.globalTxId(), transactionContext.localTxId()); } else { getLogger() .debug("Updated context {} for globalTxId:{} and localTxId:{}", context, transactionContext.globalTxId(), transactionContext.localTxId()); } context.setGlobalTxId(transactionContext.globalTxId()); context.setLocalTxId(transactionContext.localTxId()); } ```
