해결법

1. ==============================

   1.끔찍한 서식. 매개 변수를 사용하는 경우 당신은 넣지 마십시오 '?' 단순히?.

   끔찍한 서식. 매개 변수를 사용하는 경우 당신은 넣지 마십시오 '?' 단순히?.

   줄을 변경 :

   PreparedStatement pstmt = conexion.prepareStatement("INSERT INTO general_news(id,title,link,author,description,date,content) VALUES ('?','?','?','?','?','?')");
   

   에

   PreparedStatement pstmt = conexion.prepareStatement("INSERT INTO general_news(id,title,link,author,description,date,content) VALUES (?,?,?,?,?,?)");
   

   그는 당신이 0 매개 변수가 있지만 첫째을 지정하고 생각하는 이유입니다.

   또한 당신이 INSERT를 실행하는 참고 및 MUST으로하는 executeQuery를 사용하지. 사용 executeUpdate의 () 대신.
