一、UserAction中獲取到的ArrayList對象填充到UserForm中，jsp頁面獲取UserForm的初始值。
UserAction的部分代碼：
復制代碼 代碼如下:
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的部分代碼：
復制代碼 代碼如下:
private ArrayList userlist;
public ArrayList getUserlist(){
return userlist;
}
public void setUserlist(ArrayList userlist){
this.userlist=userlist;
}
JSP頁面代碼：
復制代碼 代碼如下:
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>用戶名/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>電話/b>/td>
td style="width:73px;height:16px" >b>電子郵件/b>/td>
td style="width:273px;height:16px" >b>動作/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('刪除此用戶么？')){ submitSid(document.fview,'bean:write name="user" property="username"/>')}">刪除/a>
/td>/tr>
/logic:iterate>
/logic:notEmpty>
/table>
二、UserAction中獲取到數據ArrayList對象后，把ArrayList對象存在request中，JSP頁面在獲取到ArrayList對象。
UserAction部分代碼：
復制代碼 代碼如下:
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部分代碼：
復制代碼 代碼如下:
table id="id1" borderColor="darkgreen" cellSpacing="0" border="1">
tr >
td >b>用戶名/b>/td>
td >b>角色/b>/td>
td >b>姓名/b>/td>
td >b>電話/b>/td>
td >b>電子郵件/b>/td>
td >b>動作/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('刪除此用戶么？')){ submitSid(document.fview,'bean:write name="user" property="username"/>')}">刪除/a>
/td>/tr>
/logic:iterate>
/logic:present>
/table>
