dispatcher-servlet.xml 파일

용도

• 웹 전용 파일
• view, controller 같이 웹에서 실행하는 프로그램들의 집합

Controller 자동 매핑

• 반복적으로 사용하는 웹 컴포넌트를 자동으로 매핑해줌 (Controller 객체 별도로 등록 안 해도 됨)

  1. <beans> 태그 수정 (context)

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

  2. context:component-scan 태그 추가

     <?xml version="1.0" encoding="UTF-8"?>
     <beans xmlns="<http://www.springframework.org/schema/beans>"
     	     **xmlns:context="<http://www.springframework.org/schema/context>"**	 
     	xmlns:xsi="<http://www.w3.org/2001/XMLSchema-instance>"
     	xsi:schemaLocation="
     	<http://www.springframework.org/schema/beans>
     	<http://www.springframework.org/schema/beans/spring-beans.xsd>
     	**<http://www.springframework.org/schema/context**>
     	**<http://www.springframework.org/schema/context/spring-context.xsd>"**>
     	
     	<context:component-scan base-package="com.beom"></context:component-scan>
     </beans>
     

applicationContext.xml 파일

용도

• 어플리케이션을 관리 (단독으로 사용할 수 있는 클래스)
• DAO, MyBatis 등

1. web.xml 등록 해야 함.

• <param-value> 태그 안에는 applicationContext 파일 경로 쓰기

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			/WEB-INF/applicationContext.xml
		</param-value>
</context-param>
<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

2. applicationContext.xml 파일 생성

• WEB-INF 우클릭 → new → other → spring/Spring Bean Configuration File → 이름은 applicationContext → finish
• MyBatis, DAO, Services 옮기기
