【中文标题】Hibernate 5.1.0 错误无法执行解组并且找不到元素“休眠配置”的声明

【英文标题】：Hibernate 5.1.0 Errors Unable to perform unmarshalling and Cannot find the declaration of element 'hibernate-configuration'

【问题描述】：

尝试创建一个包含单个条目的简单学生数据库。 我使用 Hibernate 5.1.0 和 mysql 作为具有简单学生表的数据库，并且无法连接到数据库。使用 Eclipse Mars 以及添加到项目中的 MYSQL jdbc 驱动程序以及 hibernate 5.1 必要的 jars。

我的 StudentInfo.java 文件

package com.nitish.hibernate;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="student")
public class StudentInfo 
    @Id
    private int rollno;
    private String name;
    private int marks;

    public int getRollno() 
        return rollno;
    
    public void setRollno(int rollno) 
        this.rollno = rollno;
    
    public String getName() 
        return name;
    
    public void setName(String name) 
        this.name = name;
    
    public int getMarks() 
        return marks;
    
    public void setMarks(int marks) 
        this.marks = marks;
    

我的 Main.java 文件

package com.nitish.hibernate;

import org.hibernate.*; 

public class Main 

    public static void main(String args[])

        StudentInfo s1 = new StudentInfo();

        s1.setName("Nitishpisal");
        s1.setRollno(5);
        s1.setMarks(33);


        try
            Configuration conf = new Configuration();
            System.out.println("Hibernate Configuration loaded"); 
            conf.configure("hibernate.cfg.xml");

            ServiceRegistry sr = new StandardServiceRegistryBuilder().applySettings(conf.getProperties()).build();
            System.out.println("registry loaded"); 

            SessionFactory sf = conf.buildSessionFactory(sr);
            System.out.println(" session factory loaded");

            Session session = sf.openSession();

            session.beginTransaction();
            session.save(s1);
            session.getTransaction().commit();
            catch(HibernateException e)
                e.printStackTrace();
               

    

我的 hibernate.cfg.xml 文件

<!DOCTYPE hibernate-configuration PUBLIC 
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

我们将不胜感激任何帮助！

【问题讨论】：

当我用这个 SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 替换我的 Main.java 文件时工作会话会话 = sessionFactory.openSession(); session.beginTransaction(); session.save(s1); session.getTransaction().commit();谢谢

【参考方案1】：

尝试删除此字符串： xmlns="http://www.hibernate.org/xsd/hibernate-configuration"

【讨论】：

似乎它不喜欢架构：Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/hibernate-configuration. Use namespace http://www.hibernate.org/dtd/hibernate-configuration instead. 尝试将"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" 替换为此http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd Надеюсь поможет:)

【参考方案2】：

在 hibernate.cfg.xml 中声明映射类后删除关闭属性标记 替换

<!-- model classes  and mapping info-->
<mapping class="com.nitish.hibernate.StudentInfo"></property>

与

<!-- model classes  and mapping info-->
 <mapping class="com.nitish.hibernate.StudentInfo">

【讨论】：

我做了，但同样的问题仍然存在

这没有帮助
