Answer 1

只用在web.xml里配置就可以了
<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>/*</url-pattern>
  </filter-mapping>

Answer 2

Spring提供Open Session In View来解决这个问题, 有两种方式
1. Interceptor     <!-- =========== OpenSession In View pattern ==============-->
    <bean id="openSessionInViewInterceptor"            class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>    <bean id="urlMapping"  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors" ref="openSessionInViewInterceptor"/>
        <property name="mappings">
            <props>
            ......
            </props>
        </property>
    </bean>
    
2. Filter <web-app>
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate.support.OpenSessionInViewFilter
</filter-class>
</filter>
 
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping></web-app>
