<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.bdqn.entity"><class name="Dog" table="Dog">  <id name="id" column="id">      <generator class="native"></generator>  </id>    <property name="name" column="name"></property>    <property name="age" column="age"></property></class></hibernate-mapping>
