在整合Spring4.2/hibernate3/SpringMVC时出现No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here报错。
以下是配置文件：

• web.xml

        <!-- 解决静态资源响应 -->
        <mvc:default-servlet-handler/>  
        <mvc:annotation-driven/>  

</beans>

经过一番搜索和思考，发现解决办法如下：
方法一：
1. 首先要开启注解事务。
2. 在service层或者dao层添加@Transactional注解
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>
参见http://blog.csdn.net/z69183787/article/details/37819831及其评论。
原理：不让springmvc管理事务，让spring管理事务.

方法二：
在web.xml中配置一个过滤器：

    <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中的某个bean id必须为”sessionFactory” ）
原理：不知道，￣□￣｜｜ ，但有篇博文好像说的有点道理，大家读懂了记得告诉我~
