Action中ArrayList显示到JSP页面的具体实例

  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>
