이전 코드에서 제목과 동일한 오류가 발생했습니다. 열 위치 '0'이 범위를 벗어났습니다. 이 ResultSet에 대한 열의 수는 '3'
나는 내 코드에서 사용자 이름 유효성 검사기를했지만, 다음 코드를 포함하는 것을 잊었다 : 나는이 문제를 해결할 것을 추가 한 후password =ESAPI.validator().getValidInput("Login password", password, "Password", 20, false);
합니다.
내 다음 java 페이지에서 동일한 문제가 발생하여 코드를 검토 한 결과 누락 된 부분을 찾을 수 없었습니다. 실제로 누락 된 부분이있는 경우입니다.
다른 코드 줄을 포함하는 것을 잊어 버렸기 때문에 내가 작업하고 있던 다른 코드와 동일한 오류가 발생하여 해결할 수있었습니다.
그러나이 코드 조각에 대해서는 여러 번 지나쳤으며 그 중 무엇이 잘못되었는지 알 수 없습니다.

코드가 등록 양식이다 : 여기
코드이다. 다음 오류가 대가로 주어 지지만 등록을 시도 할 때. 코드의pStmt.setString(0, daf.getString("username"));
그러나이 선이 나에게 올바른 같습니다

오류는 내 코드의 90 라인을 가리키는 것으로 보인다. 나는 무엇을 놓칠 수 있 었는가?
올바른 코드를 표시하도록 업데이트되었습니다. 원래 잘못된 코드를 붙여 넣었습니다. – Turk
