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。 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> |
