hibernate.cfg.xml(一般放在src目录下)

<?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"><hibernate-configuration><session-factory>        <!-- Database connection settings -->        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="connection.url">jdbc:mysql:///test</property>        <property name="connection.username">root</property>        <property name="connection.password"></property>        <!-- SQL dialect (方言)-->        <!-- 配置dialect方言,明确告诉hibernate连接是哪种数据库 -->        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>        <!-- Disable the second-level cache  -->       <!--  <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> -->        <!-- Echo all executed SQL to stdout -->        <property name="show_sql">true</property>        <!-- Drop and re-create the database schema on startup -->        <!-- <property name="hbm2ddl.auto">create</property> -->  <span style="white-space:pre"></span><!-- 映射的文件-->        <mapping resource="com/haitun/dao/user.hbm.xml"/>    </session-factory></hibernate-configuration>

user.hbm.xml(放在对应的JavaBean类下)

<?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"><!-- Generated 2015-1-15 12:41:32 by Hibernate Tools 3.4.0.CR1 --><hibernate-mapping>    <class name="com.haitun.dao.User" table="_user" catalog="bbs">        <id name="id" type="java.lang.Integer">            <column name="id" />            <generator class="identity" />        </id>        <property name="name" type="string">            <column name="name" length="64" not-null="true" />        </property>        <property name="password" type="string">            <column name="password" length="128" not-null="true" />        </property>    </class></hibernate-mapping>
