Intellij JSP - Get/Post/Service 한글 깨짐 해결

Get/Post/Service 한글 깨짐 해결

• html/JSP -> JSP

  • Get 방식

    1. page contentType 부분에 charset=UTF-8 추가

         <%@ page contentType="text/html;charset=UTF-8" language="java" %>
       

    2. 스크립틀릿에서 charset을 UTF-8로 지정

         <% response.setCharacterEncoding("utf-8"); %>
       

  • Post 방식

    1. 지시자와 스크립틀릿 사용

         <%@ page contentType="text/html;charset=UTF-8" language="java" %> <%--charset=UTF-8 추가--%>
         ...
         <% response.setCharacterEncoding("utf-8"); %>
       

    2. 스크립틀릿만 사용

         <%
        request.setCharacterEncoding("utf-8");
        response.setCharacterEncoding("utf-8");
         %>
