Spring disable transactions for a single class method

Question

In my Spring application, I have a class annotated with org.springframework.transaction.annotation.Transactional annotation.

Is it possible to discard transactions for a specific single method of this class without removing @Transactional from class level declarations? If so, please show an example

Answer 1

According to Transactional documentation:

public @interface Transactional

Describes a transaction attribute on an individual method or on a class.

So additionally to the class-level annotation just define the correct attribute at your method to disable the default transaction handling.

example:

@Transactional(propagation=Propagation.NEVER)
public long notInTransaction(AnythingData anythingData) throws Exception {
   //JDBC code...
}

Will throw an exception if this method is called inside an active transaction. Whereas Propagation.NOT_SUPPORTED will "suspend" the current transaction and make sure that the method is called non transactional.
