Question

帮我解决这个问题。它没有连接到数据库，而是使用wamp服务器作为数据库

[文件层次结构] [1]

public boolean login() {

    try{
      SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
      Session session=sessionFactory.openSession();
      session.beginTransaction();
      Query query=session.createQuery("from Login where username=:username and password=:password");
      query.setString("username", username);
      query.setString("password", password);
      List list=query.list();

      System.out.println("list size"+list.size());

       if(list.size()==1){
       return true;
       }else{
       return false;
               }
         }

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

错误：HHH000196：解析XML时出错（2）：元素类型“class”的内容不完整，它必须匹配“（meta *，subselect？，cache？，synchronize *，comment ？，的tuplizer *，的？（ID |复合-ID）下，鉴别器，天然-ID，（版本|时间戳），（财产|？多到一个|一到一个|分量|动态分量|特性|任何|地图|设为|列表|袋| idbag |阵列|原始阵列）的，（（合并，子类*）|接合子类* |联合子类？*），装载机，SQL插入，SQL更新，SQL-删除，滤波器*，取轮廓*，结果集*，（查询|？？？？。SQL查询）*）”

class中的hibernate.hbm.xml映射需要定义id（或composite-id），以及类中的属性，例如

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 
<hibernate-mapping>
   <class name = "Login.Login" table = "login1">

      <id name = "username" type = "string" column = "username">
         <generator class="assigned"/>
      </id>

      <property name = "password" column = "password" type = "string"/>
      ...
      other properties...
      ...
   </class>
</hibernate-mapping>

org.hibernate.MappingNotFoundException：resource：找不到hibernate.hbm.xml
