错误消息：线程“主”org.hibernate.HibernateException 中的异常：访问 stax 流时出错

Question

我正在尝试使用 hibernate 创建 MySQL 数据库表，但收到以下错误消息：

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 Main.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"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

感谢您的帮助

Answer 1

我遇到了同样的问题。事实证明，系统无法从提供的 url 访问 hibernate-configuration-3.0.dtd。

    <DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

所以，我从本地系统中引用了它。

    <!DOCTYPE hibernate-configuration SYSTEM
    "classpath://org/hibernate/hibernate-configuration-3.0.dtd">

对我来说效果很好。希望对您有所帮助！

清除了 hibernate.cfg.xml 文件开头的空间。成功了

<?xml version="1.0" encoding="UTF-8"?>

Answer 3

您需要关闭标签<hibernate-configuration。

<hibernate-configuration>

DOCTYPE 中没有! 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">
