早上好，当我运行我的应用程序时，我收到以下错误：

我的设置如下。如。多线程环境中的GlassFish 4.1，MySQL DB，Java 1.7，JPA（BMT + datasourse JTA）

的persistence.xml 

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence persistence_1_0.xsd"
version="1.0">
<persistence-unit name="surebet-unit" transaction-type="JTA">
<jta-data-source>surebetDB</jta-data-source>
<class>com.surebetfinder.dao.ejb.Evento</class>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/surebetdb" />
        <property name="javax.persistence.jdbc.user" value="" />
        <property name="javax.persistence.jdbc.password" value="" />
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="eclipselink.logging.level" value="ALL" />

    </properties>
</persistence-unit>

这是我的业务功能，它由异步bean

调用 
@Stateless
@TransactionManagement(value = TransactionManagementType.BEAN)
public class GestoreScommesse {
    private final static Logger log = Logger.getLogger(GestoreScommesse.class);

    @Resource
    private UserTransaction userTransaction;

    @EJB
    private SurebetService service;

private Evento creaScriveEvento(EventoMod e) throws SureBetException {
    log.debug("Cerco sul DB evento con ID " + e.getIdEvento());
    try {
        this.userTransaction.begin();
        Evento evento = null;
        List<Evento> eV = this.service.findByNativeQuery("SELECT * FROM evento WHERE ID_EVENTO = " + e.getIdEvento() + "  LOCK IN SHARE MODE", Evento.class);
        if (eV == null || eV.size() == 0) {
            log.debug("Evento non presente sul DB con ID " + e.getIdEvento());
            evento = impostaEvento(e);
            this.service.create(evento);
            log.debug("Creato nuovo evento su " + e.getIdEvento());
            this.userTransaction.commit();

        } else {
            log.debug("Evento già presente con id " + e.getIdEvento());
            evento = eV.get(0);
        }
        this.userTransaction.commit();
        return evento;
    } catch (RuntimeException | NotSupportedException | SystemException | RollbackException
            | HeuristicMixedException | HeuristicRollbackException e1) {
        try {
            log.error("Errore nella scrittura dell'evento ", e1);
            userTransaction.rollback();
            throw new SureBetException(e1);
        } catch (IllegalStateException | SecurityException | SystemException e2) {
            log.error("Impossibile eseguire rollback sulla transazione ", e2);
            throw new SureBetException(e2);
        }
    }
}

来电者：

@Stateless
@TransactionAttribute(TransactionAttributeType.SUPPORTS)
public class WorkerThread {

    private final Logger log = Logger.getLogger(WorkerThread.class);

    @EJB
    private GestoreScommesse gestore;

    @Asynchronous
    public void run(Risorsa bookmaker) throws SureBetException {
       log.debug("Eseguo esplorazione del bookmaker " + bookmaker.toString());
       gestore.creaScriveEvento(e);
       log.trace("Esplorazione terminata");
    }
}

虽然这是DAO：

@Stateless
@TransactionAttribute(TransactionAttributeType.REQUIRED)

public class SurebetService {

    @PersistenceContext
    EntityManager em;

    public <T> T create(T t) {
        this.em.persist(t);
        this.em.flush();
        this.em.refresh(t);
        return t;
    }

    public void refresh(Class<?> type){
        this.em.refresh(type);
    }

    public <T> T find(Class<T> type, Object id) {
        this.em.flush();
        return (T) this.em.find(type, id);
    }

    public void delete(Class<?> type, Object id) {
        Object ref = this.em.getReference(type, id);
        this.em.remove(ref);
    }

    public <T> T update(T t) {
        return (T) this.em.merge(t);
    }

    @SuppressWarnings("rawtypes")
    public List findWithNamedQuery(String namedQueryName){
    return this.em.createNamedQuery(namedQueryName).getResultList();
    }
    @SuppressWarnings("rawtypes")
    public List findWithNamedQuery(String namedQueryName, Map<String, Object> parameters) {
        return findWithNamedQuery(namedQueryName, parameters, 0);
    }

    @SuppressWarnings("rawtypes")
    public List findWithNamedQuery(String queryName, int resultLimit) {
        return this.em.createNamedQuery(queryName).setMaxResults(resultLimit).getResultList();
    }

    @SuppressWarnings("unchecked")
    public <T> List<T> findByNativeQuery(String sql, Class<T> type) {
        return this.em.createNativeQuery(sql, type).getResultList();
    }

    @SuppressWarnings("rawtypes")
    public List findWithNamedQuery(String namedQueryName, Map<String, Object> parameters, int resultLimit) {
        Set<Entry<String, Object>> rawParameters = parameters.entrySet();
        Query query = this.em.createNamedQuery(namedQueryName);
        if (resultLimit > 0)
            query.setMaxResults(resultLimit);
        for (Entry<String, Object> entry : rawParameters) {
            query.setParameter(entry.getKey(), entry.getValue());
        }
        return query.getResultList();
    }

    public EntityManager getEm() {
        return em;
    }

    public void setEm(EntityManager em) {
        this.em = em;
    }


}

错误不系统。有些想法？谢谢

1 个答案:

答案 0 :(得分：0)

我将从堆栈跟踪开始：

  

在   com.surebetfinder.logic.GestoreScommesse.creaScriveEvento（GestoreScommesse.java:100）

我的猜测是，if块之外的第二次调用userTransaction.commit失败，因为事务已经提交。

您可以重构代码以提交单点，或者在使用userTransaction.getStatus方法提交之前进行检查。
