EJB回滚不适用于提交异常时的容器管理事务或Bean管理事务

Question

我花了几个小时尝试使用EJB进行回滚。我有一个CDI控制器，我想在其中删除一些对象。当我试图在EJB中删除时，我得到了一个异常，我试图进行回滚，但它不起作用。在获得异常之前已通过提交执行的每个SQL都不会回滚。显然，这并不是因为当我试图在BMT中进行回滚时，我遇到了另一个异常。否则，当我尝试CMT时，我得到了hibernate的异常，但我得到了与BMT相同的结果。

我的控制器是

@Named
@Stateful
@ConversationScoped
public class PRequerimientoConjuntoCertificacionesBean implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 1779474550283190942L;
    @Inject
    private Conversation conversation;
    @PersistenceContext(type = PersistenceContextType.TRANSACTION)
    private EntityManager entityManager;
    @Inject
    private DatosSesion datosSesion;
    public void eliminarDocumento() {
        // TODO hay que probarlo
        DocumentoGeneradoSSCC documentoEliminar;
        try {
            documentoEliminar = (DocumentoGeneradoSSCC) daoBase
                    .getEntityById(DocumentoGeneradoSSCC.class,
                            10);
            documentoSSCCDAOBean.removeDocumentoSSCC(documentoEliminar,entityManager);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

使用EJB BMT如下：

@Stateful
@TransactionManagement(TransactionManagementType.BEAN)
public class DocumentoSSCCDAOBean implements IDocumentoSSCCDAOBeanLocal {
    @Resource
    private UserTransaction userTran;
    @PersistenceContext(type = PersistenceContextType.TRANSACTION)
    private EntityManager entityManager;
    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    public void removeDocumentoSSCC(
            DocumentoGeneradoSSCC documentoGeneradoSSCC,
            EntityManager entityManager) {
        // TODO hue probarlo
        try {
            userTran.begin();
            // Eliminamos recurso asignado
            entityManager
                    .remove(entityManager.contains(documentoGeneradoSSCC) ? documentoGeneradoSSCC
                            : entityManager.merge(documentoGeneradoSSCC));
            userTran.commit();
        } catch (Exception e) {
            try {
                userTran.rollback();
            } catch (IllegalStateException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (SecurityException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (SystemException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
        } 
    }
}

我得到了这个堆叠式

javax.transaction.RollbackException：ARJUNA016053:无法提交事务。

当我尝试回滚时，我会得到这个

java.lang.IollegalStateException：BaseTransaction.rollback-ARJUNA016074：没有事务！

我有一个独立的数据源，JTA=true，

<datasource jta="true" jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
    <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
    <driver>h2</driver>
    <security>
        <user-name>sa</user-name>
        <password>sa</password>
    </security>
</datasource>

我的persistence.xml是

<persistence-unit name="JusticiaGratuita"
    transaction-type="JTA">
    <!-- <description>Forge Persistence Unit</description> -->
    <provider>org.hibernate.ejb.HibernatePersistence</provider>

如果能帮我回滚并解决我的问题，我将不胜感激。

问候

Answer 1

终于解决了我的问题。我得到这个异常是因为在执行回滚之前我执行提交，因此在提交之后执行回滚是不可能的，因为这两者都是互斥的。由于这个原因，我没有得到任何事务，因为提交关闭了它，当回滚执行时就没有事务了。

java.lang.IollegalStateException：BaseTransaction.rollback-ARJUNA016074：没有交易！

最后，我决定以这种方式与CMT合作。

@TransactionManagement(TransactionManagementType.CONTAINER)
@Stateless
public class DocumentoSSCCServiceBean implements IDocumentoSSCCServiceBeanLocal {
    @EJB
    private IDaoBase daoBase;
    @PersistenceContext(unitName = "JusticiaGratuita", type = PersistenceContextType.TRANSACTION)
    private EntityManager entityManager;
    @Resource
    private EJBContext ejbContext;
    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void removeDocumentoSSCC(Long documentoGeneradoSSCC)
            throws RollbackSajgException {
        try {
            // Buscamos el documento a eliminar
            DocumentoGeneradoSSCC docu = (DocumentoGeneradoSSCC) daoBase
                    .getEntityById(DocumentoGeneradoSSCC.class,
                            documentoGeneradoSSCC);
            entityManager.remove(docu);
        } catch (Exception e) {
            ejbContext.setRollbackOnly();
            throw new RollbackSajgException();
        }
    }
}

我希望这能帮助一些人。
