Question

请帮忙 的 hibernate.cfg.xml中

<?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="hbm2ddl.auto">create</property>  
 <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>  
 <property name="connection.url">jdbc:sqlserver://localhost;databaseName=MyDB</property>  
 <property name="connection.username">sa</property>  
 <property name="connection.password">password</property>  
 <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
 <property name="show_sql">true</property>    
 <mapping resource="user.hbm.xml"></mapping>  
 </session-factory>  

</hibernate-configuration>

我没有看到文件有什么问题

user.hbm.xml

<?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="com.raj.User" table="UserData">
    <id name="id" type="int" column="id">
    <generator class="assigned"></generator>
    </id>
    <property name="email" column="email"></property>
    <property name="login" column="login"></property>
    <property name="password" column="password"></property>
    </class>

    </hibernate-mapping>

代码出了什么问题，有人请检查并帮我解决这个问题，提前谢谢

我在运行代码时得到的堆栈跟踪

1）将 hibernate.cfg.xml 更改为以下内容：

<?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.SQLServerDialect</property> 
 <property name="hibernate.hbm2ddl.auto">update</property>   
 <property name="hibernate.connection.url">jdbc:sqlserver://localhost;databaseName=MyDB</property>  
 <property name="hibernate.connection.username">sa</property>  
 <property name="hibernate.connection.password">password</property>  
 <property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
 <property name="show_sql">true</property>    
 <mapping resource="user.hbm.xml"></mapping>  
 </session-factory>  

</hibernate-configuration>

注意：需要互联网连接

2）使用以下 HibernateUtil 获取SessionFactory对象：

import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {
private static SessionFactory sessionAnnotationFactory;

public static SessionFactory getSessionAnnotationFactory() {
    if (sessionAnnotationFactory == null) {
        sessionAnnotationFactory = buildAnnotationSessionFactory();
    }
    return sessionAnnotationFactory;
}

private static SessionFactory buildAnnotationSessionFactory() {
    SessionFactory sessionFactory = null;
    try {

        sessionFactory = new AnnotationConfiguration().configure("hibernate.cfg.xml").buildSessionFactory();
    } catch (HibernateException e) {
        e.printStackTrace();
    }
    return sessionFactory;
}

}

并获取SessionFactory＆amp;会话对象使用以下代码：

SessionFactory sessionFactory = HibernateUtil.getSessionAnnotationFactory();
session = sessionFactory.openSession();

为什么我得到无法解析配置：/hibernate.cfg.xml错误
