Spring
[Spring] intellij로 Spring Maven + MVC 초기 환경 구축하기

2020. 3. 12. 13:56
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
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

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>

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

</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.
