Question

我正在尝试设置一个jdbc事务的虚拟示例来测试提交和回滚。我在这里：

启动流程的http入口点，
在db上插入一个抛出和异常的组件
db的更新。

我希望在组件异常插入之后进行回滚，但事实并非如此。调试mule源我已经看到，在类BeginAndResolveTransactionInterceptor中，insert语句以commit结束，因为resolveStartedTransaction属性设置为true。这就是为什么在默认 - 异常 - 策略回滚不起作用我想... 我不知道我在配置上做错了什么，或者是否是错误的行为。

好的我找到了解决方法。如果事务是由vm而不是jdbc启动的，那么它可以正常工作。可能在jdbc / transaction中有一个错误，它总是在第一次事务时进行提交 endpoint是jdbc。

Mule 3.3.0 Jdbc事务不需要的提交
