Dwie transakcje w restowym serwisie powodują rollback.

Witam. Mam takie proste DAO:

@RequestScoped
@Transactional
public class ProductDaoImpl implements ProductDao {

    @Override
    public void update(Product product) {
        entityManager.merge(product);
    }

    @Override
    public Product findByName(int id, String productName) {
        TypedQuery<Product> query = entityManager.createQuery("SELECT p FROM Product p WHERE p.productName = :productName and p.productId <> :id", Product.class);
        query.setParameter("productName", productName);
        query.setParameter("id", id);
        System.out.println(productName + id);
        return query.getSingleResult();
    }

}

Wywołuje je w web serwisie:

@RequestScoped
@Path("/products")
public class ProductRest {

    @Inject
    private ProductDao productDao;

    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.TEXT_PLAIN)
    public Response update(Product product) {
        Response response;
        if (productDao.findByName(product.getProductId(), product.getProductName()) != null) {
            response = Response.ok("Product exist").build();
        } else {
            productDao.update(product);
            response = Response.ok("Success").build();
        }
        return response;
    }

}

Kiedy podam nieprawidłową nazwę wszystko jest ok wywołuje się tylko metoda findByName i dostaję w odpowiedzi "Product exist". Jednak kiedy podam prawidłową nazwę i metoda ponadto przechodzi do metody update. Dostaję następujący błąd:

Czym jest to spowodowane? Dodam, że z metodą update jest wszystko ok, po wykomentowaniu findByName i wywołaniu tylko update w metodzie wszystko działa. Podobnie z innymi metodami, które zawierają w przeciwieństwie do tej jedno wywołanie metody transakcyjnej. Więc czemu przy wywołaniu dwóch metod transakcyjnych dostaję błąd? Wywołując jedną jest wszystko ok.

  1. Wyciąłeś końcówkę stacktrace która mogłaby być interesująca...
    2. Szklana kula, bo za mało kodu: Całe wywołanie serwisu masz otoczone transakcją i te wewnętrzne korzystają z zewnętrznej. Robisz findByName które rzuca wyjątkiem bo nie znajduje obiektu. To załatwia tą transakcje i w efekcie update też nie może sie wykonać poprawnie bo transakcja jest juz ustawiona na rollback.

edit: Jak wołasz getSingleResult() to dokumentacja mówi że leci wyjątek a nie zwraca sie null... I w ogóle za takie porównania z nullami zamiast używania Optional<> to powinni z ciebie drzeć skórę pasami ;]

@Shalom naprawiłem to tak, że zwracam listę getResultList, zamiast getSingleResult i potem sprawdzam czy nie jest pusta. Nie wiem czy to dobre podejście skoro spodziewam się jednego rekordu a zwracam listę. Gdybym chciał zostawić to getSingleResult to chyba musiałbym kombinować coś z transakcjami i dodawać w adnotacji transactional nad metodą update required.new. Nie mylę się.

Co do tych optionali to nie jestem jakoś do nich przekonany.

1

Tylko ze z Optionalem ten kod byłby dużo łatwiejszy i znacznie bardziej czytelny. Co do twojego pytania to sie mylisz. Wystarczyłoby złapać ten wyjątek po prostu. Swoja drogą powinni to naprawić w kolejnej wersji API i zwracać właśnie Optionala a nie rzucać wyjątkiem w takiej sytuacji ;]
Jeśli chodzi o tą listę to zawsze możesz w tej metodzie DAO to obsłużyć tzn pobrać listę i sprawdzić czy jest niepusta i zwrócic z niej pierwszy element.

1

Mogą nie naprawić, bo będą chcieli być kompatybilni ze starszymi wersjami javy.

Łapanie wyjątku i zwracanie optionala to idealny przykład sterowania przepływem z wykorzystaniem wyjątków, ale w takiej sytuacji gdy dostosowujesz jedno API do drugiego to najlepsze co możesz zrobić.

0

Problem ze sterowaniem przepływem za pomocą wyjątków to zrobili geniusze którzy rzucają tym wyjątkiem z getSingleResult() nie dając przy tym żaden alternatywy (brak metody do sprawdzenia czy rekord istnieje, brak metody tryGetSingleResult etc) ;)
Implementacji nie zmienią, ale mogą dodać nową metodę która zwraca Optional a nie rzuca wyjątek.
