Java org.hibernate.QueryException:意外标记：as

将项目切换到maven，使用最新版本的Hibernate。我被困在试图解决这个问题，确切的代码工作过。我觉得hibernate找不到映射文件之类的东西？我的所有xml文件都在resources文件夹中。使用Intellij

您不能以这种方式配置Hibernate 5（它仅对Hibernate 4有效）

Configuration

在执行

buildSessionFactory（serviceRegistry）

操作时，会丢失所有映射信息

只需使用它来构建一个

会话工厂

sessionFactory = new Configuration().configure().buildSessionFactory();

您需要提交一个事务并关闭会话。在其他情况下也不要忘记回滚。

这基本上取决于数据库。有些数据库支持关键字，有些则不支持。所以从查询中删除as，然后重试

  ts = session.createQuery("from Tickets where inplay =: inplayValue and bin < :binValule ORDER BY bin ASC";


ts.setParameter("inplayValue ", Boolean.valueOf("true");
ts.setParameter("binValule", 30);

ts.list();

ts=session.createQuery（“来自票证，其中inplay=：inplayValue和bin<:binvalueorderbybinasc”；
ts.setParameter（“inplayValue”，Boolean.valueOf（“true”）；
ts.setParameter（“binValule”，30）；
ts.list（）；

我不知道您使用的是什么ddbb，也许这可以帮助您：

我在用oracle booleans映射java booleans时遇到了很多问题

您是否尝试过不使用“t”，从任何地方删除“t”或只是删除“AS”并再次尝试哪个版本的Hibernate？请添加

HibernateUtil

code。听起来您切换到了Hibernate版本，该版本对HQL使用了稍微不同的标准。@v.ladynev 5.1。0.Final，在HibernateUtil中编辑。谢谢，为我提供了足够的信息来修复它。查阅了5.1文档，发现了与以前几乎相同的代码，工作原理与以前相同。@Switcher05不客气。Hibernate有一个不太好的文档。例如，一个不适用于Hibernate 5的示例

Configuration configuration = new Configuration().configure();
        ServiceRegistry serviceRegistry
                = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties()).build();

        // builds a session factory from the service registry
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);

sessionFactory = new Configuration().configure().buildSessionFactory();

  ts = session.createQuery("from Tickets where inplay =: inplayValue and bin < :binValule ORDER BY bin ASC";


ts.setParameter("inplayValue ", Boolean.valueOf("true");
ts.setParameter("binValule", 30);

ts.list();
