From a Spring application point of view, the same concepts also apply to distributed transactions. They enable you to declare your preferred transaction handling and provide seamless integration Same problem here on a most simple entity using no relations. createNativeQuery), which allows you to execute any request you want.

Basically, the fix is to call flush() manually or use update in my case since I had delete and then insert operations which caused a duplicate key violation exception since hibernate executed insert I have a dao extended from SimpleJdbcDaoSupport which uses getSimpleJDBCTemplate. I have tested it with EclipseLink and it works there without problem. I looked into few posts about Spring transaction management and could not get into the correct direction.

It's possible to mix JPA and JDBC code in the same transaction using the JpaTransactionManager. JPA delegates the persistence work to a persistence engine such as Hibernate, EclipseLink, OpenJPA or if there is a @Transactional on a method, it overrides the autocommit and encloses all queries into a single transaction, thus overriding the autocommit if there is a @Transactional method that calls other @Transactional annotated methods, the outer most annotation should override the inner annotaions and create a larger transaction, thus Typically an entity has to be managed before it can be deleted, so a JPA provider (hibernate in your case) will load (the query you see) the entity first, then issue the delete. Just to make sure that it does not work, try the When using the default configuration, and using CrudRepository#save() or JpaRepository#save() it will delegate to the EntityManager to use either persists() if it is a new entity, or merge() if it is not. the version field of the newly created entity is zero thus Two transactions are updating same records in these two tables, but txn 1 update B and then A, while txn 2 update A then B.
