post 방식으로 form으로 데이터를 전달하거나 URL 쿼리문에 파라미터로 던진것들은
@RequestParam을 통해 받을수 있습니다.
<소스코드>
package com.example.demo;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class SampleController {
@GetMapping("/events/form")
public String eventForm(Model model) {
Event newEvent = new Event();
newEvent.setLimit(50);
model.addAttribute("event",newEvent);
return "/events/form";
}
@PostMapping("/events")
@ResponseBody
public Event getEvent(@RequestParam(required = false , defaultValue = "sungwon") String name , @RequestParam Integer limit) {
Event event = new Event();
event.setName(name);
event.setLimit(limit);
return event;
}
}
@RequestParam도 변수명과 파라미터명이 같다면 생략 가능하며
required = false를 하면 파라미터로 값이 없어도 Bad Request가 나지 않으며
defaultValue를 통해 값을 초기화 할 수 있습니다.
