spring_SSH整合之_三个常见问题

openSessionInView执行顺序：

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

<!-- 指定你的sessionFactory名字 -->
<init-param>
<param-name>sessionFactoryBeanName</param-name>
<param-value>sessinFactory</param-value>
</init-param>

如果不配置txManager：

将抛出只读异常
