我正在尝试将我的hibernate 4.3迁移到hibernate 5.1.16,最后得到的是QuerySyntaxException,它一周后无法显示。

我正在使用注释进行映射,并且检查了所有查询,这些查询使用的是我的实体类的相同名称,我的查询中的名称没有冲突,这可以肯定,并且重点是它可以与Hibernate 4.3一起使用。

网络上所有的解决方案都只指向命名conflicts.__Maintence是我的第一个表,而映射问题则指向该表。

这是我用于映射的hibernate.cfg

<mapping class="wadetech.DB.entity.__Maintenance"/>


这是my __Maintenance

@Entity
@Table(name = "__maintenance", uniqueConstraints = @UniqueConstraint(columnNames = "name"))
public class __Maintenance implements java.io.Serializable {


这是my __MaintenanceDAO

public Collection<__Maintenance> getMaintenanceByName(String name){
    String query = "";
    query += "select m from __Maintenance m";
    query += "  where m.name = :name ";
    query += " order by ";
    query += "   m.startDate desc, m.idMaintenance desc";
    return super.list(query, "name", name);
}



这是我的例外

我还添加了我的HibernateUtil的一部分,因为我怀疑这是由于某些事务问题引起的,在我移至5.1后已更改了这些事务
在我使用tx.wasCommitted();之前

hibernate 5.1中省略了我无法使用的,因为它已被提交,所以我将其更改为以下代码tx.getStatus() == TransactionStatus.COMMITTED

这是我的hibernateUtil

public static void beginTransaction(boolean readOnly) throws InfrastructureException {

    try {
        if( currentConnectionMode == ConnectionMode.MASTER_SLAVE && readOnly ) {
            // it is a readOnly tx
            Transaction tx = readOnlyThreadTransaction.get();
            if (null == tx || tx.getStatus() == TransactionStatus.COMMITTED || tx.getStatus() == TransactionStatus.ROLLED_BACK) {
                tx = getReadOnlySession().beginTransaction();
                readOnlyThreadTransaction.set(tx);
            }
        } else {
            Transaction tx = threadTransaction.get();
            if (null == tx || tx.getStatus() == TransactionStatus.COMMITTED || tx.getStatus() == TransactionStatus.ROLLED_BACK) {
                tx = getSession().beginTransaction();
                threadTransaction.set(tx);
            }
        } // end if
    } // end try
    catch (HibernateException ex) {
        WLog.DAOLogger.error("Begin transaction", ex);
        throw new InfrastructureException(ex);
    } // end catch
}


我想坚持使用hibernate 5.1,并且不想迁移到hibernate 5.2,因为5.2使用jdk 8+。我更喜欢休眠5.1,因为我严格需要使用jdk 1.7

最佳答案

所以最后我弄清楚了我的问题。即使异常并不能指出我们的突破点,真正的问题还是在hibernateUtils上。
在此之前,我的休眠实用程序用于休眠4.3。

serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                        configuration.getProperties()).build();
                sessionFactory = configuration.configure().buildSessionFactory(serviceRegistry);


然后我将其更改为

registry = new StandardServiceRegistryBuilder().configure().build();
                 MetadataSources sources = new MetadataSources(registry);
                 Metadata metadata = sources.getMetadataBuilder().build();
                 sessionFactory = metadata.getSessionFactoryBuilder().build();
