- org.springframework-version : 5.3.27수정
- org.aspectj-version : 1.9.19 수정
- org.slf4j-version : 2.0.7 수정
junit : 4.13.2수정
org.apache.maven.plugins

4. Tomcat의 server.xml

<Context docBase="SpringLegacy" path="/springlegacy" reloadable="true" source="org.eclipse.jst.jee.server:SpringLegacy"/></Host>

path : /springlegacy 유지
예) path를 /springlegacy에서 /로 수정시 웹 애플리케이션의 URL이 localhost:8080/springlegacy에서 localhost:8080/로 변경 됨.

Tomcat까지 설정후 Tomcat 서버 Start 후 localhost:8080/springlegacy접속

5. web.xml

기존 root-context.xml & servlet-context.xml 삭제 후 재생성
(삭제하지 않고 그대로 사용해도 괜찮습니다.)

<?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"

	<!-- Listener -->

	</listener>

	<!-- Context -->

모든 서블릿과 필터 사이에서 공유되는 루트 스프링 컨테이너를 정의합니다.
스프링 컨테이너는 스프링 프레임워크에서 애플리케이션의 객체를 관리하고 의존성 주입(Dependency Injection)을 수행하는 역할을 담당합니다.
루트 스프링 컨테이너는 웹 애플리케이션 내에서 모든 서블릿과 필터가 공유하는 컨테이너입니다.

<listener>
    <listener-class> org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

모든 서블릿과 필터가 공유하는 스프링 컨테이너를 생성하는 역할을 합니다.
서블릿과 필터는 웹 애플리케이션의 요청을 처리하기 위해 스프링 컨테이너의 빈(Bean)을 사용합니다.
리스너는 스프링 컨테이너를 생성하여 모든 서블릿과 필터가 공유할 수 있도록 준비하는 단계를 나타냅니다.

<servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/config/presentation-layer.xml</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>

애플리케이션의 요청을 처리하는 단계이며 스프링 컨테이너가 요청을 적절하게 처리할 수 있도록 돕는 역할을 합니다.
스프링 기반 웹 애플리케이션에서는 서블릿과 필터가 요청을 처리하고, 해당 요청을 스프링 컨테이너로 전달하여 필요한 처리를 수행합니다.

<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>

스프링 웹 애플리케이션에서 문자 인코딩 필터를 설정합니다.
encodingFilter를 설정함으로써 요청과 응답의 문자 인코딩을 일관되게 처리할 수 있습니다.
