[코배스 - 5.2 예제 프로젝트의 로딩 구조]

스프링프레임 워크의 구동간에 관여하는 XML은 대략 3가지가 있다.

☞ 오늘 정리할 내용은 스프링프레임 워크의 web.xml, root-context.xml, servlet-context.xml에 관한 것이다.

---

1. web.xml

: web.xml에 root-context.xml과 servlet-context.xml이 등록 되어있다.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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 https://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 
    <!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/root-context.xml</param-value>
    </context-param>
    
    <!-- Creates the Spring Container shared by all Servlets and Filters -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
 
    <!-- Processes application requests -->
    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
        
    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
 
</web-app>
 

2. root-context.xml

: root-context.xml 이 실행되면서 빈(Bean) 객체들이 생성되며, 의존성 처리도 동시에 진행된다.

<?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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
    
    <!-- Root Context: defines shared resources visible to all other web components -->
        
</beans>
 

3. servlet-context.xml

: servlet-context.xml 이 실행되면서 DispatcherServlet이 실행되며, 빈(Bean) 객체생성과 동시에 root-context.xml에 생성 되었던 객체들과 의존성 처리 된다.

해당 설정 파일을 통해서 서버요청(*presentation-layer)을 받음.
