如何解决将Hibernate从3迁移到4后出现事务问题 问题更多数据和代码
问题
我已经从Hibernate 3.6.10迁移到4.3.11。这些是我的pom.xml属性：
<!--<hibernate.version>3.6.10.Final</hibernate.version>-->
<hibernate.version>4.3.11.Final</hibernate.version>
public Collection<ProtExtraccionMuestra> guardarProtExtraccionMuestras(
Collection<ProtExtraccionMuestra> protExtraccionMuestras) {
Date fechaEnTrada = null;
Date fechaSalida = null;
Collection<ProtExtraccionMuestra> muestrasRetornar = new HashSet<ProtExtraccionMuestra>();
if (protExtraccionMuestras != null) {
for (ProtExtraccionMuestra protExtraccionMuestra : protExtraccionMuestras) {
Localizador.servMuestra().comprobarMuestraEnBiobanco(protExtraccionMuestra.getMuestra());
fechaEnTrada = protExtraccionMuestra.getMuestra().getFechaEnTrada();
fechaSalida = protExtraccionMuestra.getMuestra().getFechaSalida();
protExtraccionMuestra = (ProtExtraccionMuestra) guardar(protExtraccionMuestra,true);
protocoloExtraccionService.comprobarEstadoMuestra(protExtraccionMuestra.getMuestra(),fechaEnTrada,fechaSalida);
muestrasRetornar.add(protExtraccionMuestra);
}
}
return muestrasRetornar;
}
升级后，该代码无效。我收到此错误（HibernateException：无法获取当前线程的事务同步会话）：

经过一些验证后，这是保存对象的方式：
在AbstractEntity的某些继承人中：
public AbstractEntity guardar(AbstractEntity entity,boolean merge) {
return super.modify(entity,merge);
}
public HibernateDAO getHibernateTemplate() {
return this;
}
[...]
public AbstractEntity modify(AbstractEntity obj,boolean merge) {
if (!merge) {
try {
this.getHibernateTemplate().saveOrUpdate(obj);
} catch (Exception e) {
logger.error(e);
obj = DiUtilHibernate.merge(obj,getSession());
this.getHibernateTemplate().saveOrUpdate(obj);
}
} else {
obj = DiUtilHibernate.merge(obj,this.getHibernateTemplate());
}
return obj;
}
这个可怕的实用程序类：
/**
* Merge function,to load only the required entities
*/
public static AbstractEntity merge(AbstractEntity ent,Session ses) {
// We save the values,before they are lost with the merge
String lazysCargados = ent.getLazysCargados();
boolean valorLazys = ent.getCargarLazysProxy();
return afterMerge((AbstractEntity) ses.merge(ent),lazysCargados,valorLazys);
}
如果您需要其他一些代码或说明，请告诉我。
