action代码:
private ActionForward display(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// TODO 自动生成方法存根
ArrayList arraylist = new ArrayList();
ArrayList array = new ArrayList();
// stub
String sid = request.getParameter( "sid ");
/*
* 将板块名称单独取出来
*/
op.setSname(form, request, sid);
HttpSession session = request.getSession();
arraylist = lr
.executeQuery( "select t.TNumber,s.SName,u.UName,t.TTopic,t.TTime,t.TClickCount,t.TId from bbstopic as t inner join bbssection as s on t.TSid = s.SId inner join bbsuser as u on t.TUid = u.UId where t.TSid= "
+ sid);
for (int j = 0; j < arraylist.size(); j++) {
// 在此每个array都表示一条纪录
array = (ArrayList) arraylist.get(j);
tf = new TopicForm();
for (int i = 0; i < array.size(); i++) {
tf.setTnumber(array.get(0).toString());
tf.setTsname(array.get(1).toString());
tf.setTuname(array.get(2).toString());
tf.setTtopic(array.get(3).toString());
tf.setTtime(array.get(4).toString());
tf.setTclickcount(array.get(5).toString());
tf.setTid(array.get(6).toString());
System.out.println(array.get(i));
}
array.add(tf);
}
if (array != null) {
session.setAttribute( "topics ",array);
return mapping.findForward( "showtopic ");
} else {
/*
* 如果查询的板块没有帖子
*/
return mapping.findForward( "fail ");
}
}
页面代码:
<logic:present name= "topics " scope= "session ">
<logic:iterate id= "topic " name= "topics ">
<tr>
<td> <bean:write property= "tnumber " name= "topic "/> </td>
<td> <a href= "/BBS/topic.do?method=lookup&tnumber= <bean:write property= "tnumber " name= "topic "/> &tid= <bean:write property= "tid " name= "topic "/> "> <bean:write property= "ttopic " name= "topic "/> </a> </td>
<td> <bean:write property= "tuname " name= "topic "/> </td>
<td> <bean:write property= "ttime " name= "topic "/> </td>
<td> <bean:write property= "tclickcount " name= "topic "/> </td>
</tr>
</logic:iterate>
</logic:present>
我在action里面的输出语句可以打印出来，
