SSH框架 session问题

我用的strut2 spring2 hibernate3 做了个小列子..struts.xml配置如下:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">



/list.jsp

    <action name="delTUser" class="delTUserAction">
        <result type="redirect">/list.action</result>
    </action>               

</package>

问题:
我点击删除user1 它会redirect 到list.action这上面来,,但是它还会出现user1这条记录,,再刷新后就没了..

这有什么解决方法吗? 流程是不变的,,

很传统的写法
DAO 继承HibernateDaoSupport 用getHibernateTemplate().delete(user);删除
spring 的配置如下

我用到了hibernate的延时加载..是web.xml里面设置的


contextConfigLocation
/WEB-INF/applicationContext*.xml

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<filter>
    <filter-name>opensession</filter-name>
    <filter-class>
        org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
    </filter-class>
</filter>

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.FilterDispatcher
    </filter-class>
</filter>

<filter-mapping>
    <filter-name>opensession</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

我加了getHibernateTemplate().flush(); 问题依然存在...很多SSH项目种都加这种延时,那么他们是怎么解决的呢..

    貌似是缓存的问题吧



    把这三条语句加在页面的

    里面就可以了

    你的删除user的代码应该写得有些问题吧

    导致没有马上提交删除事务

    LZ,你在删除记录后加上刷新方法吧
    比如:
    getHibernateTemplate().flush();

    session.flush();

    你的DAO 继承HibernateDaoSupport 用getHibernateTemplate().delete(user);
    这段代码部分后面加上getHibernateTemplate().flush();
    因为你用了OpenSessionInViewFilter这种方式,导致web端session还没有进行提交事务
