# root-context.xml

base-package 값에는 com.study.testapp 과 같이 프로젝트를 처음 설정할때, 작성했던 기본 패키지를 입력합니다. 그리고 beans 에서 스키마를 추가로 등록하여야 합니다.

 

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

	<!-- Root Context: defines shared resources visible to all other web components -->
	<context:component-scan base-package="com.study.testapp">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
</beans>

# servlet-context.xml

이 파일에서는 바로 하위의 context:component-scan 항목에서 Controller 어노테이션만 스캔할 수 있도록 설정을 조금 변경해줍니다.

 

<?xml version="1.0" encoding="UTF-8"?>

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

# web.xml

한글 깨짐방지 필터를 상단에 추가합니다.

 

<!-- 한글 깨짐 방지 -->
<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>

 

컨텍스트 파일 경로를 지정해줍니다.

 

<!-- 컨텍스트 파일 -->
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/spring/*-context.xml
  </param-value>
</context-param>
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

 

완성된 전체 코드입니다.
