[Spring] intellij로 Spring Maven + MVC 초기 환경 구축하기

사용환경 : intellij IDEA 2019.3.3 / tomcat 9.0.31 / SDK 1.8

tomcat 다운 : https://tomcat.apache.org/download-90.cgi에서 자신의 운영체제에 맞게 다운받으면 된다.

1. Spring Maven 프로젝트 설정

Create new project > Maven > Sdk 1.8버전으로 설정 후 next > 프로젝트 이름 설정 > finish > Enable-Auto-Import 눌러주면 완료

 

2. Spring MVC 모듈 추가 

프로젝트 이름 우클릭 > Add Frameworks Support > Spring MVC 클릭 > Download > OK

초기 생성된 구조 

프로젝트 구조

3. tomcat 사용해서 localhost 접속하기

우측 위에 있는 Edit Configurations 클릭 > + 버튼 눌러서 tomcat Server > local 클릭 

Application Server : Configuration에서 tomcat 위치 찾아서 넣기

Fix 버튼 누른 후 > Application Context의 경로 / 로 설정 하고 OK

그럼 위쪽에 Tomcat으로 설정된 모습을 볼 수 있다.

라이브러리 추가

File > Project Structure > Artifacts > Avaliable Elements아래 우클릭 > Put into Output Root > OK

web.xml 아래 url-pattern 태그 안 / 로 바꾸기

dispatcher-servlet.xml안에 beans 내용 추가

그리고 tomcat으로 실행화면 >> 이렇게 나오면 초기설정 성공!

+ web.xml에 한글 설정 코드 넣기

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 

이제 controller코드의 Model과 .jsp파일 연결해 본다

1. src/main/java/패키지명 아래 controller.java 작성

package com.hjspring.mvcboard;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class controller {

    @RequestMapping(value ="/")
    public String home(Model model){

        model.addAttribute("test","hello world!");
        return "home";
    }
}

 * 주의 : return ".jsp파일명" 과 같게 설정

2. web/WEB-INF/views 아래 home.jsp 파일 만들어 작성

<%--
  Created by IntelliJ IDEA.

--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h2>This is a first Page... ${test}</h2>
</body>
</html>

${test}로 hello world! 텍스트를 불러온다

3. dispatcher-servlet.xml에 mvc와 context를 추가한다

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:beans="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <mvc:annotation-driven/>
    <mvc:resources mapping="/resources/**" location="/resources/"/>
    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>
    <context:component-scan base-package="com.hjspring.mvcboard"/>
</beans>

그리고 실행화면

이렇게 하면 Spring MVC 초기설정은 끝이 난다. 이제 다음으로는 MysqlDB와 연동하는 방법을 알아보겠다.
