html 인코딩이 안맞는 경우(setCharacterEncoding)

빌드이너프 2023. 10. 2. 11:37 
package com.buildenough.ch2;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;
import java.util.Calendar;

@RestController
public class YoilTeller {
    @RequestMapping("/getYoil")
    public void main(HttpServletRequest request, HttpServletResponse response) throws  Exception {
        String year = request.getParameter("year");
        String month = request.getParameter("month");
        String day = request.getParameter("day");

        int yyyy = Integer.parseInt(year);
        int mm = Integer.parseInt(month);
        int dd = Integer.parseInt(day);

        Calendar cal = Calendar.getInstance();
        cal.clear();
        cal.set(yyyy, mm-1, dd);

        int dayofWeek = cal.get(Calendar.DAY_OF_WEEK);
        char yoil = "일월화수목금토".charAt(dayofWeek - 1);

        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("</head>");
        out.println("<body>");
        out.println("year = " + year);
        out.println("month = " + month);
        out.println("day = " + day);
        out.println("yoil = " + yoil);
        out.println("</body>");
        out.println("</html>");
    }
}

 

yoil의 값이 ?로 나온다

인코딩이 맞지 않기 때문

 

 

setCharacterEncoding("ms949")

        response.setCharacterEncoding("ms949"); // 한글 윈도우 MS 949
