当我使用以下代码实例化Hibernate时:
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()).buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
我有以下例外情况:
org.xml.sax.SAXParseException:文档无效:找不到语法。, org.xml.sax.SAXParseException:文档根元素 " hibernate-configuration",必须匹配DOCTYPE root" null"。 引起:org.hibernate.MappingException:配置无效 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) 在com.soccer.system.HibernateUtil。(HibernateUtil.java:23) ......还有1个 引起:org.xml.sax.SAXParseException:文档无效:未找到语法。
我在Hibernate 4.1.6中使用以下hibernate.cfg.xml
文件:
<?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"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<session-factory>

<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="connection.pool_size">1</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">update</property>
</session-factory>
</hibernate-configuration>
如何消除此异常?

添加行
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >
作为第二行(在xml版本之后和<hibernate-configuration>
标记之前。然后它应该有用。
