Action中ArrayList显示到JSP页面的具体实例

飞奔的炮台

一、UserAction中获取到的ArrayList对象填充到UserForm中，jsp页面获取UserForm的初始值。
UserAction的部分代码：

private ActionForward executeManageAction(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  UserForm userForm = (UserForm)form;
  ArrayList userlist = new ArrayList();
  SessionFactory sf= new Configuration().configure().buildSessionFactory();
  Session session=sf.openSession();
  Transaction tx=session.beginTransaction();
  String sqlQuery="from User";
  Query lQuery=session.createQuery(sqlQuery);
  userlist=(ArrayList)lQuery.list();
  tx.commit();
  session.close();
  userForm.setUserlist(userlist);
  return mapping.findForward("main_user");
 }

UsrForm的部分代码：

private ArrayList userlist;
 public ArrayList getUserlist(){
  return userlist;
 }
 public void setUserlist(ArrayList userlist){
  this.userlist=userlist;
 }

JSP页面代码：

<table id="id1" style="border-right: darkgreen 1px solid;border-top:darkgreen 1px solid;border-left: darkgreen 1px solid;width:100%;
  border-bottom;darkgreen 1px solid;border-collapse:collapse" borderColor="darkgreen" cellSpacing="0" border="1">
  <logic:notEmpty name="userForm" property="userlist">
  <tr nowrap="nowrap">
  <td style="width:80px;height:16px" nowrap><b>用户名</b></td>
  <td style="width:80px;height:16px" nowrap><b>角色</b></td>
  <td style="width:84px;height:16px" ><b>姓名</b></td>
  <td style="width:88px;height:16px" ><b>电话</b></td>
  <td style="width:73px;height:16px" ><b>电子邮件</b></td>
  <td style="width:273px;height:16px" ><b>动作</b></td>
  </tr>
  <logic:iterate indexId="index" id="user" name="userForm" property="userlist">
  <tr>
    <td noWrap style="width:80px" ><bean:write name="user" property="username"/></td>
    <td noWrap style="width:80px" ><bean:write name="user" property="role"/></td>
    <td noWrap style="width:80px" ><bean:write name="user" property="name"/></td>
    <td noWrap style="width:80px" ><bean:write name="user" property="tel"/></td>
    <td noWrap style="width:80px" ><bean:write name="user" property="email"/></td>
    <td nowrap sryle="width:273px" >
    <a href="javascript：submitSid(document.fview,'<bean:write name="user" property="username"/>')">查看</a>
    <font >||</font>
    <a href="javascript：submitSid(document.fview,'<bean:write name="user" property="username"/>')">更新</a>
    <font >||</font>
    <a href="javascript：if (confirm('删除此用户么？')){ submitSid(document.fview,'<bean:write name="user" property="username"/>')}">删除</a>
    </td></tr>
    </logic:iterate>
    </logic:notEmpty>
    </table>

二、UserAction中获取到数据ArrayList对象后，把ArrayList对象存在request中，JSP页面在获取到ArrayList对象。
UserAction部分代码：

private ActionForward executeManageAction(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  UserForm userForm = (UserForm)form;
  ArrayList userlist = new ArrayList();
  SessionFactory sf= new Configuration().configure().buildSessionFactory();
  Session session=sf.openSession();
  Transaction tx=session.beginTransaction();
  String sqlQuery="from User";
  Query lQuery=session.createQuery(sqlQuery);
  userlist=(ArrayList)lQuery.list();
  tx.commit();
  session.close();
  request.setAttribute("userlist", userlist);
  return mapping.findForward("main_user");
 }

JSP部分代码：

<table id="id1"  borderColor="darkgreen" cellSpacing="0" border="1">
  <tr >
  <td  ><b>用户名</b></td>
  <td  ><b>角色</b></td>
  <td  ><b>姓名</b></td>
  <td  ><b>电话</b></td>
  <td ><b>电子邮件</b></td>
  <td ><b>动作</b></td>
  </tr>
   <logic:present name="userlist">
  <logic:iterate indexId="index" id="user" name="userlist" >
  <tr>
    <td   ><bean:write name="user" property="username"/></td>
    <td   ><bean:write name="user" property="role"/></td>
    <td  ><bean:write name="user" property="name"/></td>
    <td   ><bean:write name="user" property="tel"/></td>
    <td ><bean:write name="user" property="email"/></td>
    <td  >
    <a href="javascript：submitSid(document.fview,'<bean:write name="user" property="username"/>')">查看</a>
    <font >||</font>
    <a href="javascript：submitSid(document.fview,'<bean:write name="user" property="username"/>')">更新</a>
    <font >||</font>
    <a href="javascript：if (confirm('删除此用户么？')){ submitSid(document.fview,'<bean:write name="user" property="username"/>')}">删除</a>
    </td></tr>
    </logic:iterate>
    </logic:present>
    </table>
