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（焊接 2.3.0 最终实现）

这是我的persistence.xml

这对我有用，断点进入TransactionalInterceptor. 手动注册TransactionalInterceptor是没有必要的。

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();
        }
    }
}
