잘못된 조합의 데이터 정렬 및 최대 절전 모드

Maria DB에 일부 캐릭터를 삽입하는 중 문제가 발생했습니다.저는 maria db connector 1.3.2 버전을 사용하고 있습니다.또한 문자를 삽입하지 말아야 하는지 또는 문자를 8자로 변환하는 옵션을 제안합니다.

최대 절전 모드 속성:

jdbc.url=jdbc\:mariadb\://localhost\:3306/twitter?useUnicode=true&characterEncoding=utf-8
hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
jdbc.username= root
jdbc.password = 
hibernate.bytecode.use_reflection_optimizer = false
hibernate.show_sql = true
hibernate.validator.apply_to_ddl = false
hibernate.connection.CharSet=utf8
hibernate.connection.characterEncoding=utf8
hibernate.connection.useUnicode = true

다음은 로그입니다.

utf8_general_ci를 언급하여 테이블을 만들었지만 latin1_swedish_ci로 만들었습니다.테이블 변경으로 문제가 해결되었습니다.정말 감사해요.

정렬 스크립트 변경: alter table_name convert to character set utf8_general_ci;
