<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
<value>cn.etity.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>

这个没有配置事务的在声明实体的时候<value>cn.etity.model</value>只可以写包明写上类名就报错

org.hibernate.MappingException: Unknown entity: cn.etity.model.User

packagesToScan的意思就是从包中浏览查找model，你直接写类肯定找不到了

User 在java中是个关键字，所以一般不能用来作类名

“packagesToScan”，直接理解就是不能写类型。
