我想编写一个验证器，该验证器将检查用户的年龄是否足以成为另一个用户的父母。因此，例如，我有以下代码，可以获取表单信息并可以检查错误：

我已经开始编写自定义验证器：
@RequestMapping(value = "/setParent", method = RequestMethod.POST)
public ModelAndView setParent(@Valid @ModelAttribute("person") Person parent, BindingResult bindingResult,
HttpServletRequest request) {
logger.info("set parent controller");
if (bindingResult.hasErrors()) {
return new ModelAndView("index", "parent", parent);
} else {
String personName = request.getParameter("personName");
String relation = request.getParameter("relation");
Person person = new Person(personName, null);
int pID = databaseModel.getPersonID(person);
int parentID = databaseModel.getPersonID(parent);
int rID = databaseModel.getRelationID(relation);
databaseModel.insertRelation(pID, parentID, rID);
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("setParentSuccess");
modelAndView.addObject("parent", databaseModel.getPersonTree(parentID));
return modelAndView;
}
}
，但随后意识到我无法获得第二个用户日期与此验证器进行比较。怎么做？谢谢
