hibernate配置hibernate-cfg.xml配置中在sessionFactory加不加名字的区别

<!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 name="foo">
		<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="connection.url">jdbc:mysql:///hibernate</property>
		<property name="connection.username">root</property>
		<property name="connection.password">root</property>
		<property name="hbm2ddl.auto">create</property>
		<property name="show_sql">true</property>
		<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
		<mapping resource="cn/hibernate/model/SysUser.hbm.xml"/>
	</session-factory>
</hibernate-configuration>

 注意：加上name会引起下面的异常

 解决办法就是去掉name=“foo”属性，因为有了name属性hibernate会试图把这个sessionfacotry注册到jndi中去。
