선행 사항 : intellij Maven project 생성

 

* Spring MVC 프로젝트 환경설정 세팅하기 (+ Maven, +Oracle , +Mybatis, +Intellij )

* Dependencies(의존성 라이브러리 정보)

- Project 태그 바로 하위

- 의존성 라이브러리 정보를 포함

- 최소 groupId, artifactId, version 정보가 필요

- dependencies 색션 아래 세부 'dependency' 

 

* Repository

- 의존성을 다운로드 받을 위치의 repository

- 기술되지 않을 시 기본적인 위치 (http://repo.maven.apache.org/maven2)

- 다수의 repository 기술 가능

 

* Build

- project 태그 바로 하위

- plugins : 빌드에서 사용할 플러그인

- 디렉터리 구조

 

2. web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
         <!-- Spring MVC 설정을 위한 xml 파일을 지정 -->
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- 파라미터 인코딩 필터 설정 -->
    <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>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

* client로부터 요청이 들어오면 DispatcherServlet 이 전달받는다.

* web.xml 에서 spring(임의지정)이라는 이름의 servlet을 정의하고 DispatcherServlet을 지정.

 

<servlet-mapping> - <url-pattern> : 웹 어플리케이션 실행 시, url에 아무 요청이 없다면(ex> localhost:포트) 

<servlet-name>으로 지정된 서블릿(spring) 실행

 

3.spring-context.xml 

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <mvc:annotation-driven/>
    <mvc:default-servlet-handler/>
    <!-- 스캔할 bean들이 모여있는 패키지를 지정한다. -->
    <context:component-scan base-package="springTest"/>

	<!-- 정적파일(이미지, 사운드, 동영상, JS, CSS 등등) 경로 셋팅 -->
    <mvc:resources mapping="/resources/**" location="/resources/" />
    
	<!-- Controller의 메서드에서 반환하는 문자열 앞 뒤에 붙힐 경로 정보를 셋팅한다. -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/view/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

<annotation-driven/> : Spring MVC 에서 정상적으로 어노테이션을 사용할 수 있도록 한다.

 

4. Run Configuration 설정

-  Run -- Edit Configuration 클릭

- +버튼 클릭 후 Maven 선택

- Name / Command line 그림과 같이 설정

community 버전은 tomcat이 안되어 jetty로 서버설정
