-com.api.listener.backoffice.STUMessageListener读取stuiputq队列并插入我们的Oracle数据库，然后将一条消息（使用新的数据库主键）发送到另一个队列（下面的ArchiveQ）。
-com.api.listener.backoffice.StorableMessageListener读取ArchiveQ队列，并尝试使用com.api.listener.backoffice.STUMessageListener插入的数据库记录的主键读取数据库 问题：

尝试将insert方法的注释更改为 @事务性（传播=传播。需要\u新建）
这将在方法完成后立即提交插入。它仍然为空，与该事务更改的金额相同。您更改了服务方法，对吗？比如->@Transactional（propagation=propagation.REQUIRES_NEW）公共存储消息存储（StorableMessage StorableMessage）{messagesDAO.save（StorableMessage）；}REQUIRES_NEW必须在StoringServiceImpl的方法中。为什么将“onMessage（）”标记为@Transactional？你试过删除它吗？这是遗留代码，就是这样，我会尝试删除OK。您可以尝试从两个“onMessage”方法中删除它。如果仍然没有帮助，请在STUMessageListener.onMessage（）中发布JMS逻辑。
