안녕하세요, 코린이의 코딩 학습기 채니 입니다.

 

개인 포스팅용으로 내용에 오류 및 잘못된 정보가 있을 수 있습니다.

Spring Legacy Project 생성

Spring Web MVC를 이용하기 위해 MVC Project Template 지정 후 Next!

 

3레벨 이상으로 작성해주며, spring2가 context-path로 사용!

jstl 추가

 

Maven 업데이트 처리!

프로젝트 우클릭 - Maven - Update Project

버전이 잘 잡힌 것을 확인할 수 있습니다.

 

server 생성

Next - 프로젝트 추가 - Finish

 

HomeController (기본 제공)

/**
 * Handles requests for the application home page.
 */
@Controller
public class HomeController {
	
	private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
	
	/**
	 * Simply selects the home view to render by returning its name.
	 */
	@RequestMapping(value = "/", method = RequestMethod.GET)
	public String home(Locale locale, Model model) {
		logger.info("Welcome home! The client locale is {}.", locale);
		
		Date date = new Date();
		DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
		
		String formattedDate = dateFormat.format(date);
		
		model.addAttribute("serverTime", formattedDate );
		
		return "home";
	}
	
}

 

home.jsp (기본 제공)

<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8" %>
<html>
<head>
	<title>Home</title>
</head>
<body>
<h1>
	Hello world!  
</h1>

<P>  The time on the server is ${serverTime}. </P>
</body>
</html>

문제 없이 작동 되는 것을 확인할 수 있습니다.
