error is not displaying in spring mvc portlet ?

[rajiv jackz，修改在12 年前。]

Hi
i done form submission in preference page of portlet for content editor.
if there is no error then properly saved into db.
i use validator to find errors if user submit wrong input or empty. if i submit wrong input but errors are not displayed in submited page . why?


The following code i use

@ActionMapping
public void doPost(@ModelAttribute("form")ResellerInfoForm form, BindingResult result, ModelMap modelMap, ActionRequest request, ActionResponse response) throws Exception
{
validator.validate(form,request, result);

if(!result.hasErrors()){
successfullPage();
}else{
response.setRenderParameter("action", "");
}
}

How to make display validation errors.

Hi,

if you use a form in your jsp page and struts, you can make your form class extends org.apache.struts.validator.ValidatorForm, instead of ActionForm.
This way you can override this method :

@Override
    public ActionErrors validate(ActionMapping mapping, HttpServletRequest req) {...}

and return an action error if some of your fields are empty, for example.

Cheers,
Cédric
