4. ConfigReader 클래스의 코드 내용
1) <server> 1레벨 정의
- server의 정보를 저장하는 객체(ServerConfig)를 서술한다.
- server의 정보에는 속성과 서버의 2레벨 정보(<server virtual-mapping virtual-mapping-list>)가 있다.
- 속성에는 documentRoot, port 정보가 있다.
2) <server virtual-mapping virtual-mapping-list> 2레벨 정의
- virtual-mapping(server/virtual-mapping-list의 하위 레벨) 정보를 저장하는 객체(VirtualMapping)를 서술한다.
- virtual-mapping의 정보에는 속성 정보가 있다.
- 속성에는 uri, path 정보가 있다.
- 2레벨은 server내에서 반복형태를 띄고 있어서 server객체에 uri를 키로하여 HashMap형태로 객체(VirtualMapping)리스트를 담아두게 된다.

7. ConfigReader2 클래스의 코드 내용
1) rulexml 을 읽어들인다.
2) rulexml 정보에 맞추어 ServerConfig.xml 을 파싱한다.
2) VirtualMapping 클래스내의 변수명에 맞추어 값이 셋팅된다.
3) < file-list >태그를 만나면 FileMapping 객체를 생성하여 VirtualMapping 클래스에 add한다.
