在整合Spring4.2/hibernate3/SpringMVC時出現No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here報錯。
以下是配置檔案：

        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <!-- 解決靜態資源響應 -->
        <mvc:default-servlet-handler/>  
        <mvc:annotation-driven/>  

</beans>

經過一番搜尋和思考，發現解決辦法如下：
方法一：
1. 首先要開啟註解事務。
2. 在service層或者dao層新增@Transactional註解
3. 把 <tx:annotation-driven transaction-manager="transactionManager" />放在springmvc.xml中就好使了或者是在springmvc.xml中配置<context:component-scan base-package="com.test.controller"></context:component-scan>
參見http://blog.csdn.net/z69183787/article/details/37819831及其評論。
原理：不讓springmvc管理事務，讓spring管理事務.

方法二：
在web.xml中配置一個過濾器：

    <filter>
       <filter-name>SpringOpenSessionInViewFilter</filter-name>
       <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
    <filter-name>SpringOpenSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
    </filter-mapping>

（注意applicationContext.xml中的某個bean id必須為”sessionFactory” ）
原理：不知道，￣□￣｜｜ ，但有篇博文好像說的有點道理，大家讀懂了記得告訴我~
