Почему @Transactional терпит неудачу для управляемого приложением EntityManager с EAP 7.2.x и 7.3.x, в то время как 7.1.x работает безупречно?

Следующий простой пример правильно работает с JBoss EAP 7.1.6 (и более ранними версиями), но не работает с EAP 7.2.x и последней версией 7.3.0.

Я создал простой воспроизводимый пример и отправил его на https://github.com/da3x/JBoss-EAP-EntityManager-Problem. Я также связываюсь со службой поддержки Red Hat... но, возможно, кто-то уже решил эту проблему.

Оба метода #save1() и #save2() делают одно и то же с разными EntityManager. Первый управляется приложением, а второй управляется контейнером.

С EAP 7.1.x оба правильно присоединяются к транзакции... с EAP 7.2.x и 7.3.x управляемый приложением не удается сбросить.

package eu.ecg.test;

import java.io.Serializable;

import javax.inject.Inject;
import javax.inject.Named;
import javax.persistence.EntityManager;
import javax.transaction.Transactional;

@Named
public class MyBean implements Serializable {

    private static final long serialVersionUID = 1L;

    private static final String VIEW_ID = "/Transactional.xhtml?faces-redirect=true";

    @Inject
    @ApplicationManaged
    private EntityManager em1;

    @Inject
    @ContainerManaged
    private EntityManager em2;

    @Transactional
    public String save1() {
        System.out.println("MyBean.save1()");
        this.em1.flush(); // NOTE: needs Transaction!
        System.out.println("OK!");
        return VIEW_ID;
    }

    @Transactional
    public String save2() {
        System.out.println("MyBean.save2()");
        this.em2.flush(); // NOTE: needs Transaction!
        System.out.println("OK!");
        return VIEW_ID;
    }
}

Оба EntityManager производятся следующим классом:

package eu.ecg.test;

import java.io.Serializable;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;
import javax.persistence.PersistenceUnit;

@ApplicationScoped
public class Persistence implements Serializable {

    private static final long serialVersionUID = 1L;

    @PersistenceUnit(unitName = "example")
    private EntityManagerFactory factory;

    @PersistenceContext(unitName = "example")
    private EntityManager em;

    /**
     * @see PersistenceContextType#EXTENDED
     */
    @Produces
    @ApplicationManaged
    public EntityManager applicationManaged() {
        System.out.println("Persistence.applicationManaged()");
        return this.factory.createEntityManager();
    }

    /**
     * @see PersistenceContextType#TRANSACTION
     */
    @Produces
    @ContainerManaged
    public EntityManager containerManaged() {
        System.out.println("Persistence.containerManaged()");
        return this.em;
    }

}

Этот урезанный пример демонстрирует основную проблему, с которой я столкнулся прямо сейчас. Реальное приложение намного сложнее и состоит из более чем 300 тысяч строк кода, но показывает такое же поведение. Хотя он правильно работает с EAP 7.0.x и 7.1.x, он не работает с 7.2.x и 7.3.0.

Я также знаю, что могу решить эту проблему, добавив em.joinTransaction() к #save1(), но, насколько мне известно, в этом нет необходимости. Аннотация @Transactional должна творить здесь чудеса... не так ли?

Мы используем EntityManager, управляемый приложением, из-за эффективного PersistenceContextType#EXTENDED, который позволяет нам выполнять отложенную загрузку с использованием управляемых объектов вне контекста транзакций — только при чтении данных.

Служба поддержки Red Hat открыла запросы на вытягивание для EAP 7.2 и 7.3:

До тех пор обходным путем является вызов EntityManger.joinTransaction() перед flush().

Нам дали ранний патч для 7.3.0, который обновляет Hibernate. Пока у нас не было проблем... но тестирование все еще продолжается. - person Daniel Bleisteiner; 26.05.2020

Мы закончили наши тесты без дальнейших проблем. - person Daniel Bleisteiner; 03.06.2020
