[GitHub] [rocketmq] SignUp-StealWheel opened a new issue #3495: 事务消息中，如何将本地事务的执行结果保存到消息体中推送到RocketMq?
SignUp-StealWheel opened a new issue #3495:
URL: https://github.com/apache/rocketmq/issues/3495
RocketMq的逻辑是：
1. 发送half消息
2. 执行本地事务
3. 发送确认消息
我想实现的需求是：
1. 执行本地事务
2. **将本地事务执行的结果保存到消息中**
有什么实现方法吗？

@xyz327 走轮询就不是rocketmq原生支持的2PC方式了，目前想的是如果只用rocketmq原生方式实现，不引入其他逻辑

https://github.com/xyz327/transactional-rocketmq-spring-boot-starter 之前基于spring做的可靠消息发送
基于spring的 TransactionSynchronization
1. 开启事务
2. 执行本地事务
3. 发送事务半消息
4. 结束事务
5. 事务完成回调处理半消息
对于你这个 我觉得可以先写消息表。然后再定时任务异步发送就好
> main-thread
1. 开启事务
2. 执行本地事务
3. 写本地消息记录表
4. 结束事务
> send-msg-thread
1. 轮询本地消息记录表发出消息

考虑用rocketmq的事务消息只是做个触发器的功能？本地事务记录要发送的消息内容。然后由事务消息去触发这个消息是否需要发送
rocketmq原生的2pc是先写消息。你现在的需求是要后写消息。完全不引入额外逻辑估计难以实现
