【问题描述】：

我正在尝试使用 maven 和 hibernate 编写 javafx 项目。当我运行应用程序时，出现以下错误：

Unable to perform unmarshalling at line number 0 and column 0 in RESOURCE hibernate.cfg.xml. Message: null.
   org.hibernate.internal.util.config.ConfigurationException: Unable to perform unmarshalling at line number 0 and column 0 in RESOURCE hibernate.cfg.xml. Message: null

用户.java：

    public class User implements Serializable {

private static final long serialVersionUID = 1L;

休眠会话工厂类：

public class HibernateSession {

    private static SessionFactory sessionFactory;

    private HibernateSession() {}

    public static SessionFactory getSession()  {
    if(sessionFactory==null) {
        try {
        Configuration configuration = new Configuration().configure();

        sessionFactory=configuration.buildSessionFactory();

        }catch(Exception e) {
            System.out.println(e);

    }
    return sessionFactory;

    }


    }

模块信息文件：

  module org.openjfx.mavenfx {
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.graphics;
    requires javafx.base;
    requires org.hibernate.orm.core;
    requires java.persistence;
    requires java.logging;
    requires java.sql;
    requires java.xml.bind;

    opens org.openjfx.mavenfx; 

    }

负责将数据放入数据库的部分代码：

Session session = HibernateSession.getSession().openSession();
        session.beginTransaction();
        User user = new User();
        user.setUserName(tfname.getText());
        user.setPassword(pf.getText());
        user.setEmail(tfemail.getText());
        session.save(user);
        session.getTransaction().commit();
        HibernateSession.closeSession();

我已经尝试过其他类似问题的解决方案。提前感谢您的帮助。

您的 hibernate.cfg.xml 不是有效的 XML。

网址中有一个&amp;，您必须使用&amp; 转义

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

谢谢，它成功了，但是在那之后我又遇到了另一个错误：

org.hibernate.boot.MappingNotFoundException: Mapping (RESOURCE) not found : org/openjfx/mavenfx/user/User.hbm.xml : origin(org/openjfx/mavenfx/user/User.hbm.xml)

在用户类中我导入了 javax.persistence.*;

我还更改了 HibernateSession 类：

public class HibernateSession {

private static SessionFactory sessionFactory;

private HibernateSession() {}

public static SessionFactory createSessionFactory()  {
    if(sessionFactory==null) {
        try {
        Configuration configuration = new Configuration().configure();
        configuration.addClass(User.class);
        StandardServiceRegistryBuilder registryBuilder = new 
   StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
        sessionFactory=configuration.buildSessionFactory(registryBuilder.build());

        }catch(Exception e) {
            System.out.println(e);
        }
    }
    return sessionFactory;
    }

    public static void closeSession() throws Exception {
    createSessionFactory().close();
    }   
  }

和hibernate.cfg.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 
3.0//EN" "http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
    <property 
name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property 
name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/mavenfxdatabase? 
useTimezone=true&amp;serverTimezone=UTC</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">root</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="current_session_context_class">thread</property>
    <property name="hbm2ddl.auto">create</property>

    <mapping class="org.openjfx.mavenfx.user.User"/>

</session-factory>
</hibernate-configuration>

是否可以在不创建 hbm.xml 文件的情况下运行应用程序？
