这是我的类，用于从数据库中获取数据

package com.javatpoint.mypackage;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.mapping.List;

public class retrive {
    public static void main(String args[]) {
        Configuration cfg = new Configuration();
        cfg.configure("hibernate.cfg.xml");// populates the data of the
                                            // configuration file

        // creating seession factory object
        SessionFactory factory = cfg.buildSessionFactory();

        // creating session object
        Session session = factory.openSession();

        // creating transaction object
        Transaction t = session.beginTransaction();

        Query query = session.createQuery("from EMPLOYEE");
        java.util.List list = query.list();
        System.out.println(list);
        t.commit();
        session.close();
    }
}

这是我的Emplouyee.hbm.xml文件：

<?xml version="1.0"?>

            <column name="LASTNAME" />
        </property>
    </class>
</hibernate-mapping>

当我运行该程序时，出现异常后，请帮助我如何解决它。我是Hibernate的新手，尝试学习但被卡住了。

Exception in thread "main" org.hibernate.hql.ast.QuerySyntaxException: 
           EMPLOYEE is not mapped [from EMPLOYEE]

虽然我能够将数据存储在数据库中，但我有2个用于第一String data和第二类的数据获取数据，但在获取数据时遇到了问题PLZ帮助。
