Spring+Hibernate中， 如果不用OpenSessionInView模式，session得手动打开和关闭，很是不爽，无疑增加了一些不必要难看的代码，配置OpenSessionInView模式也很简单，Spring提供了两种方式：
1、过滤流Filter
xml 代码
- <filter>
- <filter-name>hibernateFilterfilter-name>
- <filter-class>
- org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
- filter-class>
- filter>
-
- <filter-mapping>
- <filter-name>hibernateFilterfilter-name>
- <url-pattern>*.shtmlurl-pattern>
- filter-mapping>
2、Interceptor
java 代码
- "simpleUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
- "interceptors" ref="openSessionInViewInterceptor"/>
- "mappings">
-
<props></props>
- 。。。
- props>
- property>
- bean>
-
-
- "openSessionInViewInterceptor"
- class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
- "sessionFactory" ref="sessionFactory"/>
- bean>
推荐用第二种方式
