引用 13 楼 haizeihdj 的回复:
hibernate配置文件中必须指定hibernate.connection.provider_class属性, 
<property name="connection.provider_class">
		org.hibernate.connection.C3P0ConnectionProvider
	</property>
,然后倒入hibernate-c3p0的jar包..我也碰到这样的问题,这样解决的.具体原理我也不懂,希望高手解答.
这个确实可以用。

楼主的问题是怎么解决的？我今天也遇到这个问题了，我也是通过加载hibernate配置文件的这种方式，至今没有解决呢？

<property name="hibernate.current_session_context_class">thread</property>
改成
hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

hibernate4不能用thread了 事物交给 spring管理

按照这个方法去加载为什么不可以呢（加载hibernate配置文件的方法）？但是配置数据源后再用datasource标签加载就没问题。

----------------------------------
初始化transactionManager时出错了，应该是没法得到javax.sql.DataSource实例！

没有配置dataSource吗？配置下，然后在事物管理器中再配置下：

XML code
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory">

[/Quote]
现在的问题应该就是没有配置dataSource这个属性的问题，顺便说下，dataSource是在sessionFactory里面配的。
但是我在sessionFactory中以引用hibernate配置文件的形式配就会报错，以dataSource的形式配就没问题。不知道为什么


<!-- 配置sessionFactory -->

	<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

		<property name="configLocation">

是不是logMrg写错了，应该是logMgr

有可能是楼主大意bean写错了：Cannot resolve reference to bean 'logMgr' while setting bean property 'logMrg'
找不到bean 'logMgr' 的属性 'logMrg'
是不是logMgr或logMrg中某个字母不小心站错位置？

加了端口3306还是有问题，不是端口问题，单纯用hibernate持久化数据没问题。
