Examples with Metadata org.hibernate.boot.Metadata used on opensource projects

Example 66 with Metadata

use of org.hibernate.boot.Metadata in project hibernate-orm by hibernate.

the class TransactionsTest method cmt.

@Test
public void cmt() {
    // tag::transactions-api-cmt-example[]
    StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySetting(AvailableSettings.TRANSACTION_COORDINATOR_STRATEGY, "jta").build();
    Metadata metadata = new MetadataSources(serviceRegistry).addAnnotatedClass(Customer.class).getMetadataBuilder().build();
    SessionFactory sessionFactory = metadata.getSessionFactoryBuilder().build();
    // Note: depending on the JtaPlatform used and some optional settings,
    // the underlying transactions here will be controlled through either
    // the JTA TransactionManager or UserTransaction
    Session session = sessionFactory.openSession();
    try {
        // Since we are in CMT, a JTA transaction would
        // already have been started.  This call essentially
        // no-ops
        session.getTransaction().begin();
        Number customerCount = (Number) session.createQuery("select count(c) from Customer c").uniqueResult();
        // Since we did not start the transaction ( CMT ),
        // we also will not end it.  This call essentially
        // no-ops in terms of transaction handling.
        session.getTransaction().commit();
    } catch (Exception e) {
        // marking the underlying CMT transaction for rollback only).
        if (session.getTransaction().getStatus() == TransactionStatus.ACTIVE || session.getTransaction().getStatus() == TransactionStatus.MARKED_ROLLBACK) {
            session.getTransaction().rollback();
        }
    // handle the underlying error
    } finally {
        session.close();
        sessionFactory.close();
