org.xml.sax.SAXParseException; 文档根元素“ session-factory”，必须与DOCTYPE根“ hibernate-configuration”匹配

Question

以下是我的用于连接到MySQl Db的配置文件。

HibernateConf.cfg.xml文件

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

<!-- disable autocommit -->
<property name="hibernate.connection.autocommit">false</property>

<!-- to display sql query generated while running the programme -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>

<!-- using for JDBC transaction -->
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

<!-- for mapping -->
<mapping resource="cust.hbm.xml"/>
</session-factory>

我曾尝试更改DOCTYPE，以引用Internet上可用的材料和解决方案，但仍然低于错误。 也是因为Log4j jars，因为我也收到了警告消息吗？

错误

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.

在<session-factory>之前缺少<hibernate-configuration> ，请使用以下配置文件：

<?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><!--  Missing statement-->
<session-factory>
 <!--  connection to database -->
 <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
 <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/blrap</property>
 <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 <property name="hibernate.connection.username">root</property>
 <property name="hibernate.connection.password">oracle</property>

 <!-- disable autocommit -->
 <property name="hibernate.connection.autocommit">false</property>

 <!-- to display sql query generated while running the programme -->
 <property name="show_sql">true</property>
 <property name="format_sql">true</property>
 <property name="use_sql_comments">true</property>

 <!-- using for JDBC transaction -->
 <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

 <!-- for mapping -->
 <mapping resource="cust.hbm.xml"/>
</session-factory>
<hibernate-configuration>
