1.前段请求spring mvc controller 接口提示cannot open session
解决方法配置一个视图的拦截器，访问页面的时候被filter拦截开启session
<filter>
<filter-name>openEntityManagerInView</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>sessionFactoryBeanName</param-name>
<param-value>sessionFactory</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>openEntityManagerInView</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
2.spring service 访问repository, 接口中注入的sessionFactory 无法开启session
在commonRepository 中访问接口调用数据库的时候无法开启session
错误信息：Spring Hibernate Could not obtain transaction synchronized Session for current thread
<bean id="commonRepository" class="com.derbysoft.common.repository.CommonRepository">
