------------------------------------------
Summary: Support coordinations triggered by transaction markers
Key: ARIES-1362
URL: https://issues.apache.org/jira/browse/ARIES-1362
Project: Aries
Issue Type: New Feature
Components: Transaction
Affects Versions: transaction-blueprint-1.0.2
Reporter: Christian Schneider
Assignee: Christian Schneider
Fix For: transaction-blueprint-1.1.0
The new JPA component uses coordinations to manage the lifecycle of the JPA
EntityManager.
The blueprint transaction support should create a coordination for all
transaction markers. This will allow the JPA entitymanager to have a controlled
lifecycle that is larger than the DAO method.
So for example a service method that calls several DAO methods can be marked
with @Transactional. It will then create a coordination for the method and
close the EntityManager only after the whole service method.
If the service method does not need a transaction it can be annotated with
TxType.SUPPORTS. In this case only the coordination will be started. So the EM
lifecycle can be declared using an annotation without the performance impact of
a transaction.
