DataBinding, DataBuffering, DataValidation기능
request parameter 값을 form bean에 바인딩 해준다.
Data binding-aware tags를 사용하여 기존에 입력했던 값들이 지워지지 않게 한다.
@Controller
public class OfferController {
@Autowired
private OfferService offerService;
@RequestMapping("/offers")
public String showOffer(Model model) {
List<Offer> offers = offerService.getCurrent();
model.addAttribute("offers",offers);
return "offers";
}
@RequestMapping("/createoffer")
public String createOffer(Model model) {
//Data Buffering 을 위해 빈 model 인 Offer()를 만든다.
model.addAttribute("offer",new Offer());
return "createoffer";
}
@RequestMapping("/docreate")
public String doCreate(Model model, @Valid Offer offer, BindingResult result) {
if(result.hasErrors()) {
System.out.println("== Form data does not validated ==");
List<ObjectError> errors = result.getAllErrors();
for(ObjectError error:errors) {
System.out.println(error.getDefaultMessage());
}
return "createoffer"; //다시 돌려줌
}
//Form에서 넘어온 데이터를 Data Binding 시켜야 한다.
//Controller -> Service -> DAO
offerService.insert(offer);
System.out.println(offer);
return "offercreated";
}

기존의 스프링에서 자동으로 만들어주는 log4j를 활용하지 않고, Logback을 사용하여 로그 기능을 활용한다.
단순히 ip주소와, 홈페이지 url에 대해서만 찍어주도록 하였다.
