Spring整合Hibernate遇到的错误

            Error creating bean with name ‘transactionManager‘ defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is

org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]

           Caused by: org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]

           报这个错误的原因是用了下面的配置

<property name="hibernateProperties" value="hibernate.properties"></property>

           改成

<property name="dataSource" ref="dataSource"></property>   就可以了

 还有就是Sping3.x在整合Hibernate4.x的时候，尽量不要用org.springframework.orm.hibernate3下面的东西，换成org.springframework.orm.hibernate4吧，要不然会有很多莫名其妙的错误，会搞的头大的
