RequestParam Get방식 값 읽기

Client에서 요청할 때 Get방식으로 값을 보낼 경우 RequestParam으로 읽는다

html

<form action="/testadd" method="get">
  <div>
    <label class="form-label">TestAdd</label>
    <input type="text" name="num" value = "100">
    <button type="submit">Add</button>
  </div>
</form>

 

java spring

import org.springframework.web.bind.annotation.RequestParam;

    @GetMapping("/testadd") //ex: testadd?num=100
    public String mustache1TestaddPage(@RequestParam Long num) {
        for(int i = 0; i < num; i++) {
        	//work...
        }
        return "redirect:/list";
    }
