<html>

- 서블릿 'formgo'라는 이름을 가진 곳으로 이동

- input type="checkbox" 는 중복선택 가능

<servlet>

package ex.mystudy.ex;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Arrays;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class formgo
*/
@WebServlet("/formgo")
public class formgo extends HttpServlet {
private static final long serialVersionUID = 1L;
public formgo() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.getWriter().append("Served at: ").append(request.getContextPath());
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println(">>> doPost로 실행");
request.setCharacterEncoding("utf-8");
String name = request.getParameter("name");
String age = request.getParameter("age");
String[] hobby = request.getParameterValues("hobby");
String major= request.getParameter("major");
String email = request.getParameter("email");
response.setContentType("text/html; charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("이름 : " + name + "<br>");
out.println("나이 : " + age + "<br>");
out.println("취미 : " + Arrays.toString(hobby) + "<br>");
out.println("전공 : " + major + "<br>");
out.println("이메일 : " + email + "<br>");
}
}

- getParameter는 값 받으려고 ㅇㅇ

- getParameterValues는 값이 여러개일때(배열)

- 문자변환 해줘야 안깨지고 잘 뜸

입력후 '제출'버튼

-> consol창

-> 결과
