Java 无法分析应用程序中的配置：/hibernate.cfg.xml

我正在尝试在hibernate中执行CRUD操作。我已经为我的应用程序编写了以下步骤。 hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
    <property name="hibernate.dialect">
        org.hibernate.dialect.MySQLDialect
    </property>
    <property name="hibernate.connection.driver_class">
        com.mysql.jdbc.Driver
    </property>
    <property name="hibernate.connection.url">
        jdbc:mysql://localhost:3306/hibernate
    </property>
    <property name="hibernate.connection.username">
        root
    </property>
    <property name="hibernate.connection.password">
        root
    </property>
    <property name="connection.pool_size">1</property>

    <property name="show_sql">true</property>
    <property name="hbm2ddl.auto">create-drop</property>
    <mapping resource="Employee.hbm.xml" />
</session-factory>
</hibernate-configuration>

这是我的util类

   import org.hibernate.SessionFactory;
   import org.hibernate.cfg.Configuration;

public class HibernateUtil {

private static final SessionFactory sessionFactory;
static {
    try {
        sessionFactory = new Configuration().configure()
                .buildSessionFactory();
    } catch (Throwable ex) {
        System.err.println("SessionFactory creation failed" + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
   }

什么不起作用？错误信息是什么？你想从我们这里得到什么？！SessionFactory创建失败org.hibernate.hibernate异常：无法在com.bullraider.crud.util.HibernateUtil.（HibernateUtil.java:15）com.bullraider.crud.main.saveEmployee（main.java:24）com.bullraider.crud.main.main（main.java:15）上解析线程“main”java.lang.Exception中的配置：/hibernate.cfg.xml异常这是类路径中的错误消息is文件（在src/下）？是的，先生它在src com.bullraider.crud-->Employee.java&Main.java和com.bullraider.crud.util-->HibernateUtil.java下
