Mule 3.3.0 Jdbc事务意外提交 [英] Mule 3.3.0 Jdbc Transaction Undesired Commit

问题描述

我正在尝试设置jdbc事务的虚拟示例以测试提交和回滚.这里我有:

I'm trying to setup a dummy example of jdbc transaction to test commit and rollback. Here I've got :

• 开始流程的http入口点
• 在db上插入会引发异常的组件
• 数据库的更新.

我希望在组件异常插入之后会回滚，但事实并非如此. 调试m子源我已经看到在类BeginAndResolveTransactionInterceptor中，insert语句以commit终止，因为resolveStartedTransaction属性设置为true. 这就是为什么我认为在default-exception-strategy中无法回滚的原因... 我不知道我在配置中做错了还是行为错误.

I expect that after component exception insert were rollback but it doesn't. Debugging mule source I've seen that in class BeginAndResolveTransactionInterceptor the insert statement terminate with a commit because resolveStartedTransaction property is set to true. This is why in default-exception-strategy rollback doesn't work I suppose... I don't know if I'm doing something wrong in configuration or if is a wrong behavior.

推荐答案

好，我找到了一种解决方法.如果事务是由vm而不是jdbc启动的，则可以正常工作. jdbc/transaction中可能存在一个错误，该错误总是在首次进行事务处理时提交 端点是jdbc.

ok I've found a workaround. If transaction is started by vm instead of jdbc it works fine. Probably there is a bug in jdbc/transaction that make commit always when first transactional endpoint is jdbc.
