java.lang.ClassNotFoundException: org.hibernate.engine.SessionFactoryImplementor

Hibernate4.x与spring3.x整合，java.lang.NoClassDefFoundError: org/hibernate/engine/SessionFactory

Hibernate4.x与spring3.x整合，有关事务的处理，用Junit4测试，出现org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'txManager' defined in class path resource [beans.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/engine/SessionFactoryImplementor；

xml主要配置信息：

    <bean id="sessionFactory" 

class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

    <property name="dataSource" ref="dataSource"/>

    <property name="annotatedClasses">

    <list>

    <value>com.li.bean.User</value>

    <value>com.li.bean.Log</value>

    </list>

    </property>

    <property name="hibernateProperties">

    <props>

    <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>

    <prop key="hibernate.show_sql">true</prop>

    </props>

    </property>

  </bean>

  <bean id="txManager" 

  class="org.springframework.orm.hibernate3.HibernateTransactionManager">

  <property name="sessionFactory" ref="sessionFactory" />

</bean>

<tx:annotation-driven transaction-manager="txManager"/>

解决办法：并不是缺少jar包。目前spring3.x已经支持hibernate4.x。所以有些以前的hibernate3字眼改成hibernate4即可！正如<bean id="sessionFactory" 

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

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

   class="org.springframework.orm.hibernate4.HibernateTransactionManager">即可！

不出现报错了！
