DeltaSpike @Transactional 未被调用答案

【问题描述】：

好吧，我正在尝试使用 DeltaSpike 的 @Transactional，但从未调用过 TransactionalInterceptor。

这是我的 EntityManagerProducer：

public class EntityManagerProducer implements Serializable {

    private static final long serialVersionUID = 1L;


    private static EntityManagerFactory emf = Persistence.createEntityManagerFactory("generalPU");

    @Produces
    @TransactionScoped
    // is a bit better than @RequestScoped because it won't allow perform injection outside transaction context
    public EntityManager createEntityManager() {
        return emf.createEntityManager();
    }

    public void close(@Disposes EntityManager em) {
        if (em.isOpen()) {
            em.close();
        }
    }


    public EntityManagerFactory getEmf() {
        return emf;
    }


    public void setEmf(EntityManagerFactory emf) {
        this.emf = emf;
    }

}

我有一个注入 EntityManager 并使用 @Transactional 的类，请参阅：

@Named
@RequestScoped
public class BasicDAOImpl implements BasicDAO, Serializable {
    @Inject
    private EntityManager entityManager;

    @Transactional
    public void save(AbstractBean bean) {
    try {
        entityManager.merge(bean);
    } catch (Exception e) {
        logger.error("Erro ao tentar salvar. \n " + e);
    }
    }
}

我有一个带有拦截器的 beans.xml，看：

<?xml version="1.0"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://jboss.org/schema/cdi/beans_1_0.xsd">
     <interceptors>
        <class>org.apache.deltaspike.jpa.impl.transaction.TransactionalInterceptor</class>
    </interceptors>
</beans>

我该如何解决这个问题？我在 apache 页面 (https://deltaspike.apache.org/documentation/jpa.html) 中遵循完全相同的示例。

我正在使用 Tomcat7 + JDK 1.8 + CDI 1.2（Weld 2.3.0 最终实现）

编辑 1：

这是我的 persistence.xml

        </properties>
    </persistence-unit>

</persistence>

【问题讨论】：

您使用的是什么 CDI 实现？它的什么版本？你能分享你的persistence.xml吗？
@Jonh Ament，我用这些信息编辑了我的帖子。
只是指出 - 焊接 2.3 是 CDI 1.2 实现。我不确定你为什么使用旧版本，这会在 2.4.1.Final 上复制吗？另外，你怎么知道它没有被调用？您是否在ResourceLocalTransactionStrategy 中设置了一个断点并看到它从未被调用过？
抱歉我打错了。正如你所说，我正在使用 CDI 1.2。
我在 TransactionalInterceptor 中设置了一个断点，方法 executeInTransaction 并且从未调用过。

标签： java cdi deltaspike

【解决方案1】：

这对我有用，断点为TransactionalInterceptor。无需手动注册TransactionalInterceptor。

public class EntityManagerProducer implements Serializable {

    @Inject
    @PersistenceUnitName(value="generalPU")
    private EntityManagerFactory entityManagerFactory;

    @Produces
    @TransactionScoped
    protected EntityManager createTranEntityManager() {
        return this.entityManagerFactory.createEntityManager();
    }

    protected void closeEntityManager(@Disposes EntityManager entityManager){
        if (entityManager.isOpen()) {
            entityManager.close();
        }
    }
}

【讨论】：

我的依赖项较新。为什么要使用持久性 API 1.0？为什么选择 hibernate-validator 5.1 和 hibernate-core 3.6.10？我不认为这是一个 deltaspike 问题。
你有什么建议？
你能建一个最小的项目吗？
是的，我可以尝试使用相同的依赖项
现在的错误是：范围类型 org.apache.deltaspike.jpa.api.transaction.TransactionScoped 没有活动上下文
