@Transactional在Grails方法上给出了错误

Question

I am using Grails 2.1.1. In a controller I have a method on top I have used org.springframework.transaction.annotation.Transactional as follows:

@Transactional
def saveItem() {
    ...
}

Then it is giving this error in the console: java.lang.reflect.InvocationTargetException and showing only some code in the browser instead of form element. But if I remove @Transactional from on top of the method the view is rendering fine.

What am I missing here?

Answer 1

The support for @Transactional annotation was introduced in Grails 2.3.x so it's not working in your case and your Grails version is older.

As a workaround, either you can move all your controller business logic code to a Grails service (which are transactional by default) or wrap your controller code inside withTransaction method.

@Transactional
def saveItem() {
    AnyDomain.withTransaction {
        ...
    }
}
