@GetMapping("/converter-view")
public String converterView(Model model) {
model.addAttribute("number", 10000);
model.addAttribute("ipPort", new IpPort("127.0.0.1", 8080));
return "converter-view";
}

Form에 적용하기
@Controller
public class ConverterController {
@GetMapping("/converter/edit")
public String converterForm(Model model) {
IpPort ipPort = new IpPort("127.0.0.1", 8080);
Form form = new Form(ipPort);
model.addAttribute("form", form);
return "converter-form";
}
@PostMapping("/converter/edit")
public String converterEdit(@ModelAttribute Form form, Model model) {
IpPort ipPort = form.getIpPort();
model.addAttribute("ipPort", ipPort);
return "converter-view";
}
@Data
static class Form {
private IpPort ipPort;
public Form(IpPort ipPort) {
this.ipPort = ipPort;
}
}
}<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form th:object="${form}"th:method="post">
th:field<input type="text"th:field="*{ipPort}"><br/>
th:value<input type="text"th:value="*{ipPort}">(보여주기 용도)<br/>
<input type="submit"/>
</form>
</body>
</html>Form에도 적용 가능하다.
converterForm()
th:field가 자동으로 컨버전 서비스를 적용해
${{ipPort}}를 해준 것처럼 IpPort에서 String 타입이 되었다.
converterEdit()
@ModelAttribute가 내부적으로 컨버전 서비스를 사용해 String에서 IpPort로 변환한다.
