// MemberForm
package hello.hellospring.controller;
public class MemberForm {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
강의대로 spring1을 등록했을 때, null값이 들어와서 회원 목록에 가보면 1번에 빈값이 찍히고, 이후에 spring2를 등록하려하면 화이트라벨 에러가 나옵니다.. 놓친 부분이 어딘지 알 수 있을까요?

This application has no explicit mapping for /error, so you are seeing this as a fallback.

안녕하세요. 재훈님
올려주신 소스코드를 보았는데 저와 같은 이유가 맞네요.
createMemberForm.html 에서
// 현재 코드
<input type="text" id="name" placeholder="PLZ, Input your name">
// name="name" 추가
<input type="text" id="name" name="name" placeholder="PLZ, Input your name">아래와 같이 name 키 속성을 넣어주면 정상 동작합니다!
찾아보니 input 태그에서 값을 전달하려면 name 속성을 주어야 파라미터로 전송을 할 수 있다고 하네요.
이전에 답변해주신 David 님께도 감사합니다!

구글 드라이브의 공유 설정된 링크입니다. 압축푸셔서 강의에서 처럼
HelloSpringApplication
을 실행하거나 , 하단의 콘솔창의 실행 버튼 또는
상단의 [Build]메뉴의 [Build Project] [rebuild Project]로
실행하신 후, http://localhost:8080 로 접속하여 [회원가입]
클릭 후, 영어로 이름 입력 후,
콘솔창에 입력한 영어값이 나오면 정상상태입니다만
(현재는 계속 null 이 나오고 있으며, 한글로 입력하면
500에러가 나오는 상태입니다.)

MemberService 에서 클래스의 시작 부분과 생성자 부분의
MemberRepository를 MemoryMemberRepository로 변경(아래와 같이)
하였지만, 여전히 입력한 이름값이 콘솔에서 null로 나오고
있습니다.

안녕하세요. 저도 같은 문제 겪고 있는데, 답변 부탁드려도 될까요??
이름을 영어로 입력하면 콘솔에서 그냥 null 이 출력되고 , 한글로 입력해 보니 아래와 같은 500 에러가 나오네요. 에러 내용을 보니, MemoryMemberRepository 의 findByName에서 문제가 나오는데.. member service에서 join에서 부터 잘 저장되지 않는 것 같습니다.

먼저, member service에서 join할 때 데이터가 잘 저장되는지 확인해주세요.
findByName에서 null이 나오는 문제는 그 다음에 해결할 수 있을 것 같습니다.
member service, member repository 코드도 함께 올려주시면 좋을 것 같습니다.
