Safely handle Hibernate “SET TRANSACTION must be f

问题:

I'm not sure if I'm asking the correct question to begin with, apologies in advanced.

Question

I am wondering if it is possible to have some type of handler to rollback an erroneous transaction in Hibernate. I am having a problem which, whenever an error comes up during a batch update from Hibernate the "SET TRANSACTION must be first statement of transaction" error comes up and I would not be able to do any other query after that.

Thanks :)

Hibernate don't have an automatic transaction management system, so you have to issue the begin, commit and roll back commands by yourself.

If you are using spring this can be a lot more easier with spring transaction management API

For example,

@Transactional
void updateFoo(Foo foo){
//do your stuff
}

In the above example a new transaction will be started at the beginning of the updateFoo() method commited at the last line. If there is any problem in between the transaction will be rolled back.
