迁移到休眠后无法连接到数据库4

我试图从3.6.10.Final更新休眠到4.3.6.Final。随着3.6.10一切正常。我改名为改变类新的类名，并获得那面没有错误，但是当我运行web应用，我得到一个错误：迁移到休眠后无法连接到数据库4

2015-06-12 10:44:35.345 ERROR SchemaUpdate:201 - HHH000319: Could not get database metadata 
java.sql.SQLException: Connections could not be acquired from the underlying database!

与Hibernate 3.6.10的应用程序的context.xml是这样的：

总之

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

已更改为

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

而且

<bean id="transactionManager" 
     class="org.springframework.orm.hibernate3.HibernateTransactionManager">

到

<bean id="transactionManager" 
     class="org.springframework.orm.hibernate4.HibernateTransactionManager">

难道我误了一些变化，这是造成现在连接失败？

您需要删除以下属性：

<prop key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider 
<prop key="hibernate.c3p0.min_size">3</prop> 
<prop key="hibernate.c3p0.max_size">50</prop> 
<prop key="hibernate.c3p0.timeout">1800</prop> 
<prop key="hibernate.c3p0.idle_test_period">100</prop>

休眠已经使用外部dataSource所以它不使用internal ConnectionProvider mechanism。

你得到一个例外，因为Hibernate会忽略正确配置dataSource，并尝试使用C3P0ConnectionProvider，你不提供一个URL，user，password为此。

谢谢。看来连接现在正在工作，但现在我得到这个错误：'java.lang.NoSuchMethodError：org.hibernate.SessionFactory.openSession（）Lorg/hibernate/classic/Session; \t at org.springframework.orm.hibernate3.SessionFactoryUtils.doGetSession（SessionFactoryUtils.java:328）'看来它仍然使用hibernate3 –

完成。链接是：http://stackoverflow.com/questions/30801597/java-lang-nosuchmethoderror-org-hibernate-sessionfactory-opensessionlorg-hibe –
