从 hibernate 4.3 迁移到 hibernate 5.1.16 有 QuerySyntaxException

Question

我正在尝试将我的 hibernate 4.3 迁移到 hibernate 5.1.16，但我最终得到的是 QuerySyntaxException，一周后无法计算。

我正在使用注释进行映射，我检查了我的查询，所有这些都使用与我的实体相同的名称 class，我的查询中的名称没有冲突，这一点是肯定的，而且重点是它适用于 Hibernate 4.3。

网上的所有解决方案都只指向命名conflicts.__Maintence是我的第一个table映射问题指向这个table.

这是我用来作图的hibernate.cfg。

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

这是my __Maintenanceclass

@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

我也在添加我的 HibernateUtil 的一部分，因为我怀疑这是由于一些交易问题引起的，我在搬到 5.1 后改变了这些问题在我使用 tx.wasCommitted();

之前

我不能再使用了，因为在 hibernate 5.1 中省略了 Committed，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
}

我想继续使用 hibernate 5.1，不想迁移到 hibernate 5.2，因为 5.2 使用 jdk 8+。我更喜欢 hibernate 5.1 因为我严格需要使用 jdk 1.7

Answer 1

所以最后我解决了上述问题 was.Even 尽管异常并没有帮助指出问题。真正的问题出在 hibernateUtils 上。在此之前，我的 hiberenate utils 是如何用于 hibernate 4.3 的。

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

我把它改成了

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

从 hibernate 4.3 迁移到 hibernate 5.1.16 有 QuerySyntaxException

Migrating to hibernate 5.1.16 from hibernate 4.3 have QuerySyntaxException

java

migration

hibernate

transactions

hibernate-5.x
