[EJB3.1] Transaction rollback : Comment gérer les Exceptions ?

**piemur2000** · 03/02/2012, 11h26

Bonjour,

Lors de la sauvegarde de certaines entités de mon application je procède à une vérification (dans @PrePersist et @PreUpdate) afin d'être sur qu'elle est valide. Si elle ne l'est pas je lance une exception afin de "rollbacker" la transaction. Tout fonctionne bien, l'entité n'est pas sauvegardée.

Cependant je n'arrive pas à comprendre comment je suis sensé gérer les exceptions découlant de ce rollback. J'aimerai juste savoir que la transaction a été "rollbacké" et pourquoi afin de remonter l'information à l'utilisateur. Au lieu de ça je me retrouve avec plein de stack trace dans mon log et je ne sais pas quelle exception catcher.

Voila à quoi resemble mon log:

Ma question est donc la suivante: comment gérer les transaction rollback?

    private void prePersist() { throw new RuntimeException("Test runtime exception in prePersist"); }

    public String getName() {  return name;  }
    public void setName(String name) { this.name = name; }
}

public class TestSession {
 
    private static final Logger logger = Logger.getLogger("TestSession");
    @PersistenceContext
    private EntityManager em;
    @Resource
    private SessionContext ctx;
 
    public void testRollback() {
        try {
            TestEntity entity = new TestEntity();
            em.persist(entity);
        } catch (RuntimeException ex) {
            logger.severe("Runtime exception catched in session bean.");
            if (ctx.getRollbackOnly()) {
                logger.info("Context rollbacked.");
            } else {
                logger.info("Context is ok.");
            }
        }
    }
 
    public void testRollback2() {
        try {
            TestEntity entity = em.find(TestEntity.class, new Long(1));
            if (entity != null) { entity.setName("test"); }
 
            em.flush();
 
        } catch (RuntimeException ex) {
            logger.severe("Runtime exception catched in session bean.");
            if (ctx.getRollbackOnly()) {
                logger.info("Context rollbacked.");
            } else {
                logger.info("Context is ok.");
            }
        }
    }
}

Lorsque je lance une exception dans la methode @PrePersist de mon entité, tout se passe normalement: la transaction est "rollbacké" et je peux catcher mon exception pour en informer l'utilisateur.

Par contre lorsque je lance un exception dans la methode @PreUpdate, je vois apparaitre dans mon code des messages me disant qu'une exception à été lancée avec la stack-trace correspondante. La transaction est "rollbacké" et je peux catcher l'exception, mais, si eclipselink log des erreurs ça doit être que je fais quelque chose de travers. Qu'en pensez vous?
