我正试图使用hibernate创建一个MySQL数据库表，但我收到以下错误消息：
Exception in thread "main" org.hibernate.HibernateException: Error accessing stax stream
at org.hibernate.boot.cfgxml.internal.JaxbCfgProcessor.unmarshal(JaxbCfgProcessor.java:107)
at org.hibernate.boot.cfgxml.internal.JaxbCfgProcessor.unmarshal(JaxbCfgProcessor.java:65)
at org.hibernate.boot.cfgxml.internal.ConfigLoader.loadConfigXmlResource(ConfigLoader.java:57)
at org.hibernate.boot.registry.StandardServiceRegistryBuilder.configure(StandardServiceRegistryBuilder.java:163)
at org.hibernate.cfg.Configuration.configure(Configuration.java:259)
at com.anika.hibernate.Main.main(Main.java:18)
Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[2,34]
这个答案不能解决我的问题：Error connecting with database using hibernate
Exception in thread "main" org.hibernate.HibernateException: Error accessing stax stream
这是我的主.java文件：
package com.anika.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class Main {
public static void main(String[] args){
Student_Info student = new Student_Info();
student.setName("Anika");
student.setRollNo(1);
SessionFactory sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(student);
session.getTransaction().commit();
session.close();
sessionFactory.close();
}
}
我的hibernate.cfg.xml：
<?xml version='1.0' encoding='utf-8'?>
<DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

谢谢你的帮助
最佳答案
您需要关闭标记<hibernate-configuration。<hibernate-configuration>!中没有DOCTYPE字符：
<DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
应该是
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
