org.hibernate.HibernateException:Could not parse configuration/hibernate.cfg.xml
初学hibernate配置文件都是自己写的
下面是错误信息:
org.hibernate.
HibernateException: Could not parse configuration: /hibernate.cfg.xml
at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2216)
at org.hibernate.cfg.Configuration.configure(Configuration.java:2128)
at ch03.hibernate.Test.main(Test.java:11)
Caused by:
org.dom4j.DocumentException: Error on line 2 of document : 文档中根元素前面的标记必须格式正确。 Nested exception: 文档中根元素前面的标记必须格式正确。
at org.dom4j.io.SAXReader.read(SAXReader.java:482)

下面是我运行的代码:
package ch03.hibernate;
import org.hibernate.*;
import org.hibernate.cfg.*;
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
try{
SessionFactory sf=new Configuration().configure("/hibernate.cfg.xml").buildSessionFactory();
Session session=sf.openSession();
Transaction tx=session.beginTransaction();
User user=new User();
user.setUsername("Hibernate");
user.setPassword("123");
session.save(user);
tx.commit();
session.close();
}catch(HibernateException e){
e.printStackTrace();
}
}
}
下面是配置文件hibernate.cfg.xml
<?xml version="1.0" encoding='utf-8'?>
