Hibernate 5.2.10.Final-javax.persistence.TransactionRequiredException:没有正在进行的事务
从Hibernate 4.3迁移到5.2后,我得到了错误javax.persistence.TransactionRequiredException:没有事务正在进行中。什么会导致此错误?为什么交易不存在Hibernate 5.2.10.Final-javax.persistence.TransactionRequiredException:没有正在进行的事务,java,hibernate,migration,Java,Hibernate,Migration,从Hibernate 4.3迁移到5.2后,我得到了错误javax.persistence.TransactionRequiredException:没有事务正在进行中。什么会导致此错误?为什么交易不存在 public class HibernateUtil { private static StandardServiceRegistry registry; private static SessionFactory sessionFactory; private static final Lo

session.beginTransaction().commit();
启动并立即提交(结束)事务。但是您的flush()
需要在两者之间进行。请尝试以下方法:
protected static void storeObject(Object object) throws DAOException {
Transaction tx = null;
try {
Session session = Helper.getHibernateSession();
session.saveOrUpdate(object);
tx = session.beginTransaction();
session.flush();
tx.commit();
} catch (HibernateException he) {
if(tx != null){
tx.rollback();
}
throw new DAOException(he);
}
}
我有相同的错误,但所有操作都类似于:Session Session=HibernateUtil.getSessionFactory().openSession();尝试{session.beginTransaction();session.saveOrUpdate(entityObj);session.getTransaction().commit();}catch(运行时异常e){session.getTransaction().rollback();e.printStackTrace();}最后{session.flush();session.close();}使用事务隐式和直接使用之间有一些区别吗?谢谢,这对我帮助很大!
protected static void storeObject(Object object) throws DAOException {
Transaction tx = null;
try {
Session session = Helper.getHibernateSession();
session.saveOrUpdate(object);
tx = session.beginTransaction();
session.flush();
tx.commit();
} catch (HibernateException he) {
if(tx != null){
tx.rollback();
}
throw new DAOException(he);
}
}
