查找出错误点：web.xml配置中

<!-- 解决hibernate延迟加载带来的异常，配置过滤器使Session在请求完成之后再关闭 -->  
    <filter>  
       <filter-name>OpenSessionInViewFilter</filter-name>  
       <filter-class>  
           org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
       </filter-class>  
    </filter>  
    <filter-mapping>  
       <filter-name>OpenSessionInViewFilter</filter-name>  
       <url-pattern>/*</url-pattern> 
</filter-mapping>

解决方法：在以上代码中加入

    <init-param>
        <param-name>sessionFactoryBeanName</param-name>
        <param-value>sessionfactory</param-value>
    </init-param>

修改为：

<filter>  
       <filter-name>OpenSessionInViewFilter</filter-name>  
       <filter-class>  
           org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
       </filter-class>
       <init-param>
            <param-name>sessionFactoryBeanName</param-name>
            <param-value>sessionfactory</param-value>
        </init-param> 
    </filter>  
    <filter-mapping>  
       <filter-name>OpenSessionInViewFilter</filter-name>  
       <url-pattern>/*</url-pattern> 
</filter-mapping>
