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:

复制代码 代码如下:

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:
复制代码 代码如下:

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

JSP页面代码:
复制代码 代码如下:

    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:
复制代码 代码如下:

 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:
复制代码 代码如下:

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>
