关于logic标签的问题

Question

刚开始我以为是request范围的问题  ，结果不是。他老是不释放。
大家帮帮忙吧。 我为这个耽误了一天了。

Answer 1

session的我也试过了,也不行,难道用page么 
  这是jsp中的部分代码: 
      html:form action="/orderAction.do" method="post">
        <html:submit>        </html:submit>
        <html:text property="orderID">
        </html:text>
    </html:form>  
<table border="1" bgcolor="ccff99">
       <tr>
            <td>订单号</td>
            <td>用户编号</td>
           <td>11111111111</td>
            <td>提交时间</td>
            <td>总价</td>
            <td>是否付款</td>
            <td>狀態</td>
        </tr>
        <logic:present name="order">
            <logic:iterate id="orderview" name="order">
                <tr>1-----
                    <td>
                        <bean:write name="orderview"/>                   </td>                </tr>
            </logic:iterate>
        </logic:present>
    </table>
   这是action中的代码:
package bookshop;import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.Action;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import java.io.*;
import java.util.ArrayList;
import javax.servlet.http.HttpSession;public class orderAction extends Action {
    Connection conn;
    ArrayList list = new ArrayList();
    ResultSet rst = null;
    boolean bool = false;
    public ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) {
        orderActionForm orderActionForm = (orderActionForm) form;        DBOperation db = new DBOperation();
        String orderID = orderActionForm.getOrderID();
        request.setAttribute("order", null);
        System.out.println("orderid==============" + orderID);
        try {
            String sql = "select * from shop_user where userid ='" + orderID +
                         "'";            System.out.println("得到连接￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥");
            rst = db.select(sql);
            System.out.println("select++++++++%%%%%%%%%%%%%%%%%%%%%%%%%%" + sql);
            while (rst.next()) {
                list.add(rst.getString(1));
                System.out.println("rst.getString = " + rst.getString(1));
                list.add(rst.getString(2));
                bool = true;
                request.setAttribute("order", list);            }        } catch (SQLException ex) {            System.out.println("Exception!!!!!!!!!!!!!" + ex.toString());
        }        return mapping.findForward("success");        // return new ActionForward(mapping.getInput());
    }
}

Answer 2

在你的while循环里面加上一句list.clear()方法，就可以了。

Answer 3

把ArrayList list = new ArrayList();这句定义放到execute方法中试试
