无法在行号 -1 处执行解组

如何解决无法在行号 -1 处执行解组

我只想使用 hibernate 创建一个简单的 java 程序。我为此创建了一个 Maven 项目。

我创建了两个文件，一个是hibernate配置文件，另一个是app.java文件。

两个文件都在下面。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration SYstem "https://www.hibernate-org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
  <session-factory>
    <properties name="connection.driver_class">com.MysqL.jdbc.Driver</properties>
    <properties name="connection.url">jdbc:MysqL://localhost:3306/myhiber</properties>
    <properties name="connection.username">root</properties>
    <properties name="connection.password">root</properties>
    <properties name="dialect">org.hibernate.dialect.MysqLDialect</properties>
    <properties name="hbm2ddl">update</properties>
    <properties name="show_sql">true</properties> 
  </session-factory>    
</hibernate-configuration>

这是我的 hibernate.cfg.xml 文件

package com.tutorial.MavenProject;



import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
/**
 * Hello World!
 *
 */
public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Project World!" );
        SessionFactory factory=new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
        
        /*Configuration cfg=new Configuration();
        cfg.configure("hibernate.cfg.xml");
        SessionFactory factory=cfg.buildSessionFactory();*/
        
        System.out.println(factory);
        System.out.println(factory.isClosed());
    }
}

这是我的 app.java 文件。

现在，当我构建并运行我的 app.java 时，我遇到了这样的异常。我是 hibernate 的初学者，所以不知道如何解决这个问题。

Project World!

我不知道我在这里犯了什么错误。
