Spring4整合Hibernate4出现的错误的解决

时间:2022-09-20 11:51:04
今天在使用Spring4整合Hibernate4过程中出现错误
org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

错误的原因是由于hibernate4修改了hibernate3中 getCurrentSession()方法的支持,需要在service层注解@Transactional
具体的代码如下:

  15. <!-- 基于注释的业务,当注释中发现@Transactional时,使用id为transactionManager的事务管理器 -->
  16. <!-- 如果没有设置transaction-manager的值,则spring以缺省默认的事务管理器来处理事务,默认事务管理器为第一个加载的事务管理器 -->
  17. <tx:annotation-driven transaction-manager="transactionManager"/>
  18. <!-- 定义视图解析器 -->
  19. <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  20. <property name="prefix">
  21. <value>/WEB-INF/jsp/</value>

  23. <property name="suffix">
  24. <value>.jsp</value>
  25. </property>
  26. </bean>
  27. </beans>
然后在Service层添加@Transactional注解即可
