**openSessionInView执行顺序：**

**![Center][]  
sessinFactory名字指定：**

**严重: Servlet.service() for servlet default threw exception**

**org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessinFactory' is defined**

**异常原因:**

**spring里面的SessionFactory的id不叫sessionFactory名字。所以找不到sessinFactory。如果要想被找到sessionFactory名字。**

**1,把sessinFactory的id值设为sessinFactory**

**2,在openSessionInView的filter里面加上,你的sessionFactory的id值**

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