再打开com.yourcompany.struts.action下的AddAdminAction.java添加（其中如果有错误选中好按ctrl+shift+o自动添加包）
public class AddAdminAction extends Action {
// --------------------------------------------------------- Instance Variables
// --------------------------------------------------------- Methods
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
* @author Coder Guo
*/
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
AddAdminForm addAdminForm = (AddAdminForm) form;
// TODO Add a new admin
Admin admin = new Admin();
admin.setName(addAdminForm.getName ());
admin.setPassword(addAdminForm.getPassword ());
AdminDAOFactory adminDAO = new AdminDAOFactory ();
adminDAO.add(admin);
return mapping.findForward("success");
}
}
再打开com.yourcompanyname.struts.form下的AddAdminForm.java，修改（如果有错误按照上面说的方法导入包）
public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
ActionErrors errors = new ActionErrors();
Session session = SessionFactory.currentSession();
Transaction tx = session.beginTransaction ();
Query query = session.createQuery("select admin from Admin as admin where admin.name = " + this.name + "");
,
Iterator it = query.iterate ();
if (it.hasNext()){
errors.add ("addAdmin.err.name",new ActionMessage("form.addAdmin.err.name"));
}
tx.commit();
SessionFactory.closeSession ();
return errors;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
this.name=null;
this.password=null;
}
再打开com\yourcompanyname\struts下的ApplicationResource.properties在这里面添加错误信息：
Form.addAdmin.err.name=err
最后，（汗，好累啊-_-!）打开addAdmin.jsp修改成如下：
<%@ page contentType="text/html; charset=utf-8"%>
<%@ page language="java"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<script language = "javascript">
<!--
function check(){
if (loginForm.userName.value == "" || loginForm.password.value == ""){
alert("请输入完整的信息！");
loginForm.userName.focus();
return false;
}
}
//-->
</script>
