EntityManager persist() method does not insert record to database

Question

I have problem with using EntityManager.persist(Object) method. Now when i get rid of other problems, by app work without Exception but object is not put in my data

Answer 1

I was able to fix the same problem by adding the Entity to persistence.xml:

<persistence-unit name="OwnerPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>com.test.domain.local.Entity</class>
    <exclude-unlisted-classes />
    </persistence-unit>
</persistence>

Answer 2

Try this:

em.getTransaction().begin();
em.persist(entity);
em.getTransaction().commit();

PS: You should set a generation method for your ID as well.

Answer 3

Are you getting a specific exception? It would be helpful to know what it is if you are.

There are a number of similar problems to this already on Stackoverflow:

Spring transactional context doesn't persist data

Spring, Hibernate & JPA: Calling persist on entitymanager does not seem to commit to database

These suggest that you should try adding em.flush() after the em.persist(chain), and altering the @transactional annotations

You should also check that you have enabled transactional annotations through a line such as :

<tx:annotation-driven transaction-manager="transactionManager"/> 

in your .xml configuration
