</body>
</html>可是页面显示时调用struts那块内容却无法显示
我的控制端代码是这样的:public String selectNotice()throws Exception{
List<DormNotice> list=new ArrayList();
dormNoticeDAO=new DormNoticeDAO();
list=dormNoticeDAO.searchNotice();
if(list==null){
System.out.println("查询结果不存在");
}
else{
ActionContext ctx = ActionContext.getContext();
Map map = ctx.getSession();
map.put("newNotice", list);
}
return SUCCESS;
}麻烦大家帮帮忙.....
下面我想显示的关于数据内容并没有
我希望的是table里显示公告的
题目 title
类型 type
内容 content
发布时间 published
把你的status="list" 改成 id="list" <tr><td bgcolor="#ffffff" ><s:property value="title" /></td></tr>
<tr><td bgcolor="#ffffff"><s:property value="type" /></td></tr>
<tr><td bgcolor="#ffffff" ><s:property value="content" /></td></tr>
<tr><td bgcolor="#ffffff" ><s:property value="published" /></td></tr>
把value="title"改成 value="#list.title" 往下同理
我改过之后 就谈出错误了:
Servlet.service() for servlet default threw exception
java.lang.NullPointerException

BaseDAO文件是这样的: package com.txsm.crm.dao;import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;public class BaseDAO {
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory()
{
return sessionFactory;
} public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public Session getSession()
{
Session session=sessionFactory.openSession();
return session;
}
}
然后我发现applicitinContext配置文件里只有
<property name="mappingResources">
<list> <value>com/txsm/crm/vo/Userinfo.hbm.xml</value></list>
</property>
的配置,但是com/txsm/crm/vo包了还有一个DormNotice.hbm.xml的文件
现在我该怎么做啊....
<value>com/txsm/crm/vo/DormNotice.hbm.xml</value>
<s:property value="#stuts.index+1"/>
是你这里有问题吧，
public Session getSession()
{
Session session=sessionFactory.openSession();
return session;
}应该不是sessionFactory.openSession()吧，而是sessionFactory.getCurrentSession();
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

ActionContext act=ActionContext.getContext();
Map map=act.getSession();
map.put("newNotice", list);
这段代码写错位置了 我原来是将它写在service里的 当然这应该是个低级错误 将它写在action就可以了
贴出来大家分享下....
