我实际上是hibernate的新手，并试图建立一个类，供应商。 以下是一些细节。
的hibernate.cfg.xml
<head>
<title>App</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %> # problematic line
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>

这是我的问题。
org.hibernate.MappingException：无法获取org.hibernate.persister.entity.SingleTableEntityPersister的构造函数

throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static SupplierGui getSupplier() {
return supplierInter;
}
}
我真的不知道他们代码中的错误在哪里，有人可以帮助我吗？我是新来的尝试休眠，如果你想帮助我，我真的很开心。
thanks =）
答案 0 :(得分：0)
我认为您可以通过将此行添加到hibernate.cfg.xml
来解决 <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
