JSTL Formatting Tags
JSP의 시작 부분에 taglib 정의를 추가한다.
<fmt:bundle> Tag
resource bundle을 불러온다.
basename 속성에 지정된 properties 파일을 locale 에 맞는 것을 불러온다.
properties 파일은 패키지 형식의 이름을 가진다.
com\study\messages 에 messages.properties, messages_ko.properties, messages_en.properties 이 있다면
basename="com.study.messages.messages" 이라고 지정하면 된다.
locale이 ko 이라면 messages_ko.properties 파일을 불러오며, 해당되는 것이 없다면 message.properties 파일을 불러올 것이다.
<fmt:bundle basename="로드 할 번들 베이스 이름"
prefix="key명칭의 공통적인 부분" />
<fmt:message> Tag
메시지 키와 지역화된 메시지를 바꾸어 출력한다.
<fmt:message key="메시지 키"
bundle="사용할 번들" />
<fmt:setLocale> Tag
locale 변경
<fmt:setLocale value="locale" />
