Question

我正在尝试使用cfg文件中的hibernate连接到mysql数据库

   <?xml version='1.0' encoding='utf-8'?>

 <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" 
   "http://hibernate.sourceforge.net/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://localhost:3306/test</property>
        <property name="hibernate.connection.username">
            root</property>
        <property name="hibernate.connection.password">
            root</property>
        <property name="hibernate.connection.pool_size">
            10</property>
        <property name="show_sql">true</property>
        <property name="dialect">
            org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.hbm2ddl.auto">
            update</property>

        <!-- Mapping files -->

        <mapping resource="Employee.hbm.xml" />
    </session-factory>
</hibernate-configuration>





   private static SessionFactory factory;

        public static void main(String[] args) {
            try {
                factory = new Configuration().configure().buildSessionFactory();
            } catch (Throwable ex) {
                System.err.println("Failed to create sessionFactory object." + ex);
                ex.fillInStackTrace();
                ex.printStackTrace();
                throw new ExceptionInInitializerError(ex);
            }

虽然我的连接字符串，用户名，密码是正确的，并且在基本的jdbc连接的其他项目中工作正常但是当我使用hibernate尝试它时我在控制台上收到此错误

 Exception in thread "main" java.lang.ExceptionInInitializerError
    at com.hibernate.ManageEmployee.main(ManageEmployee.java:21)
Caused by: org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

是的，数据库服务器已启动并正在运行，但此hibernate应用程序的连接被拒绝

问题是xml解析器正在尝试访问配置文件中指定的模式文件。您运行程序的方框可以访问互联网吗？
