EJB回滚不适用于容器管理事务或Bean管理事务处理提交异常 [英] EJB Rollback does not work with Container Management Transaction or Bean Managament Transaction on commit exception

问题描述

我花了几个小时，试图用EJB来回滚。我有一个CDI控制器，我想删除一些对象。当我尝试在EJB中删除时，我得到一个异常，我尝试做回滚，但它不工作。在执行之前已经执行的每个SQL获取异常都不会回滚。 Obviusly这不是因为当我尝试在BMT中回滚时，我还有另一个例外。否则，当我尝试使用CMT我得到一个例外的hibernate，但我得到相同的结果，BMT。

我的控制器是

  @Named 
 @Stateful 
 @ConversationScoped 
 public class PRequerimientoConjuntoCertificacionesBean implements Serializable {
 
 / ** 
 * 
 * / 
 private static final long serialVersionUID = 1779474550283190942L; 
 
 @Inject 
私人对话会话; 
 
 @PersistenceContext（type = PersistenceContextType.TRANSACTION）
 private EntityManager entityManager; 
 
 @Inject 
 private DatosSesion datosSesion; 
 
 public void eliminationinarDocumento（）{
 // TODO hay que probarlo 
 DocumentoGeneradoSSCC documentoEliminar; 
 try {
 documentoEliminar =（DocumentoGeneradoSSCC）daoBase 
 .getEntityById（DocumentoGeneradoSSCC.class，
 10）;文件系统
} catch（Exception e）{
 // TODO自动生成的catch块
 e.printStackTrace（）; 
} 
} 
} 
  

使用EJB BMT如下：

  @Stateful 
 @TransactionManagement（TransactionManagementType.BEAN）
 public class DocumentoSSCCDAOBean实现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色调probarlo 
尝试{
 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自动生成的catch块
 e1.printStackTrace（）; 
} catch（SecurityException e1）{
 // TODO自动生成的catch块
 e1.printStackTrace（）; 
} catch（SystemException e1）{
 // TODO自动生成的catch块
 e1.printStackTrace（）; 
} 
} 
} 
} 
  

我得到这个堆栈跟踪

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

当我尝试回滚我得到这个

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

我有独立的数据源与JTA = true，

 < datasource jta =truejndi-name =java：jboss / datasources / ExampleDSpool-name =ExampleDSenabled =true java的上下文= 真 > 
< 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>

我的persistence.xml是

我希望有任何帮助可以回滚并解决我的问题。

注意

解决方案

最后我解决了我的问题。我得到这个异常，因为在执行回滚之前，我执行提交，因此它是不可执行的，在执行后执行回滚，因为它们都是互斥的。因为我没有交易，因为提交关闭它，当回滚执行时没有事务。

java.lang.IllegalStateException：BaseTransaction最后我决定用CMT这样做。

  @TransactionManagement（TransactionManagementType.CONTAINER）
 @Stateless 
 public class DocumentoSSCCServiceBean实现IDocumentoSSCCServiceBeanLocal {
 
 @EJB 
私人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（）; 
 
} 
} 
} 
  

我希望这可以帮助别人。

I spent hours triying to do a rollback with EJB. I have a CDI controller where I want to remove some object. When I try to remove in EJB I get an exception and I Try to do rollback, but It does not work. Every SQL which has been execute with commit before get the exception does not rollback. Obviusly It is not because I get another exception when I try to do the rollback in BMT. Otherwise when I tried with CMT I get an exception of hibernate but I get the same results that BMT.

My controller is

@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();
        }
    }
}

With EJB BMT as follows:

@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();
            }
        } 
    }
}

and I get this stacktrace

javax.transaction.RollbackException: ARJUNA016053: Could not commit transaction.

and when I try to do rollback I get this

java.lang.IllegalStateException: BaseTransaction.rollback - ARJUNA016074: no transaction!

I have standlone datasource with JTA=true,

<datasource jta="true" jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

I would appreciate any help to do rollback and solve my problems.

Regards

解决方案

Finally I solve my problem. I was getting this exception because before of doing the rollback I execute commit, therefore It is imposible execute rollback after commit as those both are exclusive each other. Cause of that I got no transaction, because commit close it and when rollback execute there was no transaction.

java.lang.IllegalStateException: BaseTransaction.rollback - ARJUNA016074: no transaction!

Finally I decided to do in this way with CMT.

@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();

        }
    }
}

I hope this could help someome.
