4. Steps to build a prototype (Banking)
• Data Model
• JAXB and JPA Annotations
• Test persistence
• E4 Application
• Simple UI
• Complex UI
• Working Example
10. DB Persistence
• Persist and Load with JPA
public static void persistDB(Bank bank){
EntityManager em = instance().getEntityManager();
em.getTransaction().begin();
em.merge(bank);
em.flush();
em.getTransaction().commit();
}
public static Bank loadDB() throws JAXBException {
EntityManager em = instance().getEntityManager();
em.getTransaction().begin();
TypedQuery<Bank> query = em.createQuery(SELECT_BANK, Bank.class);
Bank bank = query.getSingleResult();
return bank;
}
Usage: TestPersistence.java
