<!DOCTYPE hibernate-configuration PUBLIC

<hibernate-configuration>
    <session-factory>
    
        <!-- 数据库连接信息 -->
        <!-- <property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</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

            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
