HTTP 응답 데이터 - 단순 텍스트, HTML

HTTP 응답 메시지는 주로 다음 내용을 담아서 전달한다.

단순 텍스트 응답

PrintWriter writer = resp.getWriter();
writer.println("OK");

HTML 응답 HTML을 반환할 때는 content-type을 text/html 로 지정해야 한다.⭐️

package hello.servlet.basic.response;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

@WebServlet(name="responseHtmlServlet", urlPatterns = "/response-html")
public class ResponseHtmlServlet extends HttpServlet {
    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //1.Content-Type : text/html;charset=utf-8
        resp.setContentType("text/html");
        resp.setCharacterEncoding("utf-8");

        PrintWriter writer = resp.getWriter();
        writer.println("<html>");
        writer.println("<body>");
        writer.println("  <div>안녕?</div>");
        writer.println("</body>");
        writer.println("</html>");
    }
}
