pom.xml 수정하게 되면 우측 상단의 maven 아이콘 클릭하여 업데이트

src/main/webapp/WEB-INF 에 web.xml, root-context.xml, servlet-context.xml 파일 추가
web.xml

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->

    <!-- 프로젝트 패키지이름 확인 -->
    <context:component-scan base-package="com.test.project01" />

</beans:beans>

servlet-context.xml 에서 패키지 이름 설정 -중요!!

src/main/webapp/WEB-INF에 views 폴더 추가
src/main/webapp/WEB-INF/views 에 index.jsp 추가

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>index</title>
</head>
<body>
<h2>hello spring framework!!</h2>
</body>
</html>

src/main에 java 디렉토리 추가

java 에 패키지 추가 - servlet-context.xml 에서 작성한 패키지와 동일하게 생성

  • 참고 : 패키지 보기 방식(폴더 구조,패키지구조 등..) 변경

project01 에 controller 패키지 추가
HomeController.java 생성

package com.test.project01.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class HomeController {
    @GetMapping("/")
    public String index() {
        return "index"; // => index.jsp 출력
    }
}

Tomcat 설정
플러그인에서 Smart Tomcat 설치

실행 전 Edit Configurations에 Smart Tomcat 추가하기

  • Tomcat server : 설치 경로
  • Context path : url 수정
  • VM options : 한글 설정

실행
우측 하단에 팝업되는 메세지 enable annotation..클릭

실행이 완료되면 console 화면에서 localhost:8080/ 클릭

결과
