spring整合session出现问题

问题：

1.no session or session was closed

2.Could not obtain transaction-synchronized Session for current thread

解决：

在web.xml中配置OpenSessionInViewFilter

 <!--配置Session -->    <filter>        <filter-name>openSession</filter-name>        <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>openSession</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>
