Questions about Spring MVC not going to roll

Configuration is the normal configuration

I'm not going to stick it out.

The key is the automatic injection of service packs

Be sure to scan in the parent container , or the transaction cannot be rolled back

The so-called parent container

Spring and spring MVC are a little different

Simply speaking, spring is the parent container.

Spring MVC is a sub-container (may not be appropriate)

Other words

<!--service Pack (auto-inject)--><context:component-scan base-package= "Demo.service"/>

Put it in Applicationcontext.xml if you put it in Springmvc.xml, the transaction will be problematic. Transactions that are not scanned by the parent container will not be rolled back
