出错信息：

java.lang.NoClassDefFoundError: org/dom4j/DocumentException
at query.HibernateUtil.<clinit>(HibernateUtil.java:26)
at query.QueryFrame.getEmployees(QueryFrame.java:28)
at query.QueryFrame.actionPerformed(QueryFrame.java:63)
at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1849)
at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2169)
at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:420)
at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:258)
at javax.swing.plaf.basic.BasicB

出错提示中的at query.HibernateUtil.<clinit>(HibernateUtil.java:26)是这句
sessionFactory=new Configuration().configure().buildSessionFactory();

具体的程序如下：

package query;
import query.HibernateSessionFactory;

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

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class HibernateUtil {

private static Log log=LogFactory.getLog(HibernateUtil.class);

private static final SessionFactory sessionFactory;
static {
try {

sessionFactory=new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
ex.printStackTrace();// TODO: handle exception
throw new ExceptionInInitializerError(ex);
}

}

public static final ThreadLocal session=new ThreadLocal();

public static Session currentSession()throws HibernateException{
Session s=(Session)session.get();
if(s==null||!s.isOpen()){
s=sessionFactory.openSession();
session.set(s);
}

return s;

}

public static void closeSession()throws HibernateException{
Session s=(Session)session.get();
session.set(null);
if(s!=null)s.close();
}
}

Hibernate配置文件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="connection.username">test_root</property>
<property name="connection.url">
jdbc:mysql://localhost:3306/test
</property>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="myeclipse.connection.profile">
mysqlprofile
</property>
<property name="connection.password">test_root</property>
<property name="connection.driver_class">
org.gjt.mm.mysql.Driver
</property>
<property name="max_fetch_depth">1</property>
<mapping resource="com/model.hbm.xml" />

</session-factory>

</hibernate-configuration>

另一个配置文件：

model.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE Hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="query.Employee" table="employee" catalog="test">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="assigned" />
</id>

<property name="username" type="java.lang.String">
<column name="name" />
</property>

<property name="department" type="java.lang.String">
<column name="department" />
</property>
<property name="salary" type="java.lang.Long">
<column name="department" />
</property>

</class>
</hibernate-mapping>
