体会真正的Struts开发(2期)8
下面我们编写生成的文件
首先LogonForm.java文件
public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors=super.validate(mapping,request);
if(errors==null){
errors=new ActionErrors();
}
if((password==null)||(password.trim().length()==0)){
errors.add("password",new ActionError("password"));
}
if((userName==null)||(userName.trim().length()==0)){
errors.add("userName",new ActionError("userName"));
}
return errors;
}
修改Action类
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LogonForm logonForm = (LogonForm) form;
Session s = null;
try {
s = YJBaseHBM.currentSession();
} catch (HibernateException e) {
e.printStackTrace();
ActionErrors errors = new ActionErrors();
errors.add("hbm.session.error",
new ActionError("hbm.session.error"));
saveErrors(request, errors);
return mapping.findForward("failure");
}
try {
Query q=s.createQuery("from UserInfo ui where ui.userName=:user and password=:password");
q.setString("user", logonForm.getUserName());
q.setString("password", logonForm.getPassword());
System.out.println(q.toString());
Iterator it = q.iterate();
if(it.hasNext()==false){
ActionErrors errors = new ActionErrors();
errors.add("no.user",
new ActionError("no.user"));
saveErrors(request, errors);
return mapping.findForward("failure");
}
YJBaseHBM.closeSession();
} catch (HibernateException e) {
e.printStackTrace();
ActionErrors errors = new ActionErrors();
errors.add("hbm.session.query",
new ActionError("hbm.session.query"));
saveErrors(request, errors);
return mapping.findForward("failure");
} catch (Exception e1){
e1.printStackTrace();
ActionErrors errors = new ActionErrors();
errors.add("hbm.session.query",
new ActionError("hbm.session.query"));
saveErrors(request, errors);
return mapping.findForward("failure");
}
return mapping.findForward("success");
}
logon.jsp与struts-config.xml配置修改见下载文件
