<!DOCTYPE hibernate-configuration PUBLIC    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><hibernate-configuration>    <session-factory>            <!-- 数据库连接信息 -->        <!-- <property name="connection.url">jdbc:Oracle:thin:@localhost:1521:orcl</property>        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>        <property name="connection.username">db2</property>        <property name="connection.password">db2</property> -->                        <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>                <!-- 其他配置 -->        <property name="show_sql">true</property>        <property name="hbm2ddl.auto">update</property>        <mapping resource="com/msit/ssh/sh/entity/User.hbm.xml"/>                        <!-- <class-cache            class="org.hibernate.test.legacy.Simple"            region="Simple"            usage="read-write"/> -->    </session-factory></hibernate-configuration>

里边注入数据源（datasource）；再把hibernate配置文件引入进来    或者hibernate所有配置都写在sessionfactory中（舍弃了hibernate配置文件）    <!-- sessionFactory(管理hibernate sessionfactory) -->    <bean id="sessionFactory"        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">        <!-- 注入数据源 -->        <property name="dataSource" ref="dataSource" />        <!-- 引入hibernate.cfg.xml -->        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>    </bean>    

如果使用此方式:                <bean id="hibernatedaosuppert"        class="org.springframework.orm.hibernate3.support.HibernateDaoSupport"        abstract="true">        //将sessionFactory注入给HibernateDaoSuppert        <property name="sessionFactory" ref="sessionFactory"></property>        </bean>        //dao层Bean必须配置parent="hibernatedaosuppert"            <bean id="userdao" class="com.msit.ssh.sh.dao.impl.UserDaoImpl"            parent="hibernatedaosuppert">            </bean>            还想用注解怎么办？        //编写一个超类继承HibernateDaoSuppert        public class BaseHibernateDaoSuppert extends HibernateDaoSupport{                @Resource            //注入sessionFactory            public void setMySessionFactory(SessionFactory sessionFactory){                this.setSessionFactory(sessionFactory);            }            }                //dao层就继承超类        @Repository("userdao")        public class UserDaoImpl extends BaseHibernateDaoSuppert implements IUserDao
