A print threadben így inditom el a másik szálat:
| Code Block |
|---|
new Thread(new Runnable() { |
...
@Override |
...
public void run() { |
...
logger.trace("START PRINT THREAD => getNewDatasAndPrint() THREAD"); |
...
EntityManager entityManager = createEntityManager(); |
...
try { |
...
entityManager.getTransaction().begin(); |
...
bkp_POSPrintService.getNewDatasAndPrint(entityManager); |
...
entityManager.getTransaction().commit(); |
...
entityManager.close(); |
...
logger.trace("END PRINT THREAD => getNewDatasAndPrint() THREAD"); |
...
} catch (Exception ex) { |
...
if (entityManager.getTransaction().isActive()) { |
...
entityManager.getTransaction().rollback(); |
...
} |
...
entityManager.close(); |
...
logger.warn("PRINT THREAD EXCEPTION2: " + ex.getMessage()); |
...
} |
...
} |
...
}).start(); |
az entity managert így hozom létre:
| Code Block |
|---|
public static EntityManager createEntityManager() { |
...
EntityManagerFactory createEntityManagerFactory = Persistence.createEntityManagerFactory(entityManagerUnitName); |
...
return createEntityManagerFactory.createEntityManager(); |
...
} |
