I need some clarification regarding Spring transation.
In ClassA I am creating a declaritive transaction. From ClassA I am calling method1() of ClassB.
ClassB is having @Transactional(propagation = Propagation.REQUIRED) annotation in classs level.
In method1() I am doing a save operation.

My question is, when that data will be committed ? Will it be committed while control will come out from
method1()? or in ClassA where we are committing the transaction manually ?.

Code:

ClassA

class ClassA 

 void myMethod() 
 TransactionStatus status = null;
 DefaultTransactionDefinition def =
 new DefaultTransactionDefinition(TransactionDefinition.PROPAGATION_REQUIRES_NEW);
 def.setTimeout(contentFileProcessingConfigBean.getFileCopyTransactionTimeout());
 status = transactionManager.getTransaction(def);

 b.method1();

 if (status != null) 
 transactionManager.commit(status);
 
 

ClassB

@Transactional(propagation = Propagation.REQUIRED)
class ClassB 

void method1() 

//doing save operation

Probably after B.method1() finishes the aspect which is wrapping the call to @Transactional (visible in the stack trace) will commit the transaction. However this will depend on:

• Are A and B are both Spring beans?


• Is the same transactionManager bean used by transactions in A and B?


• Maybe if A is written using TransactionTemplate instead of plain TransactionManager object.

Mixing the manual and declarative transaction management is not recommended as you have to guess. I guess it will come to transactionManager which you are not showing.
