OpenSessionInView模式运用

转自：http://kewb.iteye.com/blog/128726，自己常用第一种，留作随笔！

 

Spring+Hibernate中OpenSessionInView模式运用

配置OpenSessionInView模式也很简单，Spring提供了两种方式：

1、过滤流Filter

<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>
            org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>
 
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>

2、Interceptor

<!-- SimpleUrlHandlerMapping -->    
    <bean id="simpleUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors" ref="openSessionInViewInterceptor"/>        
        <property name="mappings">
          <props>       
             。。。               
          </props>    
        </property>
    </bean>
    
    <!-- =========== openSessionInViewInterceptor ==============-->
    <bean id="openSessionInViewInterceptor"
          class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

推荐用第二种方式
