我正在使用Spring MVC并且我正在创建一个Validator,但看起来Spring从未运行它。
这是我的验证器现在很容易检查两个字段
public class MemberRequestValidator implements Validator {
public boolean supports(Class aClass) {
return MemberRequest.class.equals(aClass);
}
public void validate(Object obj, Errors errors) {
MemberRequest mr = (MemberRequest) obj;
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "content", "Content field is Required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "areacode", "Area code field is Required");
}
}
现在我的控制器如下所示:
@InitBinder("memberrequest")
public void initMemberRequestBinder(WebDataBinder binder) {
binder.setValidator(new MemberRequestValidator());
}
@RequestMapping(value = "/save", method = RequestMethod.POST)
public ModelAndView saveRequest(@ModelAttribute @Valid MemberRequest mr, BindingResult result)
{
if (result.hasErrors())
{
LOGGER.debug("Pages had errors on it... returning to input page");
return new ModelAndView("question");
}
else
{
String Ticket = mService.sentWebRequest(mr);
Map<String, Object> model = new HashMap<String, Object>();
Ticket t = new Ticket();
t.setTicketDetails(Ticket);
model.put("ticket", t);
return new ModelAndView("thanks", model);
}
}
在我的JSP页面中,我有以下内容:
<c:url var="saveUrl" value="/mrequest/save.html" />
<form:form modelAttribute="memberrequest" action="${saveUrl}" name="memberrequest" id="memberrequest">
所以,如果我不在表格中输入任何数据,我应该点击错误,但我不是吗?
答案 0 :(得分:2)
在处理程序中使用@ModelAttribute("memberrequest")
或在表单中使用modelAttribute =“memberRequest”并@initBinder("memberRequest")
