Question

将项目切换到maven，使用最新版本的Hibernate。我坚持试图解决这个问题，确切的代码以前工作过。在我看来，某种程度上hibernate无法找到映射文件或什么？我在资源文件夹中有我的所有xml文件。使用Intellij。

Answer 1

您无法以这种方式配置Hibernate 5（仅适用于Hibernate 4）

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);

执行Configuration时，

buildSessionFactory(serviceRegistry)会丢失所有地图信息。

只需使用它来构建SessionFactory

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

Hibernate 5 :- org.hibernate.MappingException: Unknown entity

您需要提交事务并关闭会话。别忘了在其他情况下回滚。

Answer 2

它基本上取决于数据库。一些db支持作为关键字，有些则不支持。所以从查询中删除然后尝试

  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();

Answer 3

我不知道你在做什么ddbb，也许这可以帮到你： http://www.service-architecture.com/articles/database/mapping_sql_and_java_data_types.html

我通过使用oracle布尔值来映射java布尔值的许多问题
