[Spring] Spring MVC - 세팅 파일 예시 및 설명

스프링 세팅 파일에는 대표적으로 3개의 xml파일이 있다.

1. web.xml (세팅 파일 지정 및 기초 설정)

2. servlet-context.xml (서블릿 - 화면 이동에 관한 세팅)

3. root-context.xml(DB 정보 세팅)

 

web.xml만 이름이 같고 나머지는 이름이 다를수도 있다.

 

1.web.xml 코드

<?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 -->

	  <filter-name>encodingFilter</filter-name>

	</filter-mapping>
	<!--  문자 인코딩  끝 -->

</web-app>

 

2. servlet-context.xml

 

서블릿 - 화면 이동에 관한 세팅을 여기서 한다.
