12. 핸들러 메소드 4부 - 폼 서브밋 (타임리프)
폼을 보여줄 요청 처리
- GET /events/form
- 뷰: events/form.html
- 모델: “event”, new Event()
@Controller
public class SampleController {
@GetMapping("/events/form")
public String eventsForm(Model model) {
Event newEvent = new Event();
newEvent.setLimit(50);
model.addAttribute("event", newEvent);
return "events/form";
}
@PostMapping("/events")
@ResponseBody
public Event createEvent(@RequestParam String name, @RequestParam Integer limit){
Event event = new Event();
event.setName(name);
event.setLimit(limit);
return event;
}
}HTMl 뷰로도 테스트할 수 있고 포스트맨을 사용해 테스트할 수도 있다.
뷰 생성
타임리프
- @{}: URL 표현식
- ${}: variable 표현식
- *{}: selection 표현식
