當我使用下面的代碼實例化休眠:休眠:文件是無效的:沒有語法發現
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()).buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
我得到了以下情況除外:
org.xml.sax.SAXParseException:文件無效:找不到語法。, org.xml.sax.SAXParseException:文檔根元素 「hibernate-configuration」必須匹配DOCTYPE根「null」。 所致:org.hibernate.MappingException:無效配置 在org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2014) 在org.hibernate.cfg.Configuration.configure(Configuration.java:1931) 在org.hibernate.cfg.Configuration.configure(Configuration.java:1910) at com.soccer.system.HibernateUtil。(HibernateUtil.java:23) ... 1 more 引起自:org.xml.sax.SAXParseException :文檔無效:找不到語法。
我用下面的hibernate.cfg.xml
文件與Hibernate 4.1.6:
<?xml version='1.0' encoding='utf-8'?>
<hibernate-configuration
xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"

<property name="connection.url">jdbc:derby://localhost:1527/K:\db</property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->

<property name="show_sql">true</property>

</session-factory>
</hibernate-configuration>
我能做些什麼來消除這種異常?
添加'DOCTYPE'是不夠的,我也不得不從'冬眠,configuration'元素中刪除所有屬性。覺得奇怪的是有利於休眠'DTD'了'XSD'。ÿ你也可以更新'DTD' url來使用'「http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd」'而不是舊的sourceforge URL。 – Sydney
