에 의해 발생 : java.sql.SQLException : 지원되지 않는 문자 인코딩 'utf8mb4'

나는 utf-8 인코딩을 많이 사용할 응용 프로그램을 작성 중입니다. 서버의 경우 java 서블릿을 사용하고 있으며 UI의 경우 jsp 및 javascript와 함께 Java Servlet을 사용하고 있습니다.
그래서 언젠가 횡설수설을 무시한 후에 나는 utf-8 인코딩 문제를 해결하기로 결정했습니다. 솔루션을 찾고있을 때 필터 클래스를 만들었습니다.
@ 과 함께 계속 개발 중이므로 @ cosoant의 대답은 https://stackoverflow.com/questions/138948/how-to-get-utf-8-working-in-java-webapps까지 "MySQL 데이터베이스 및 테이블"까지 (제외) 최대 입니다.
그럼 난 MySQL의의 UTF8 정확히 세계 UTF 8의 나머지 아니라고 이해, 그래서에의 persistence.xml에 characterEncoding 변경이 다음, 또한 <property name="hibernate.connection.characterEncoding" value="utf8mb4" /> : 나는 MySqlServer을 업그레이드 https://mathiasbynens.be/notes/mysql-utf8mb4 링크 및 추가 :에 의해 발생 : java.sql.SQLException : 지원되지 않는 문자 인코딩 'utf8mb4'

는 [클라이언트] = utf8mb4

[MySQL의] 기본 문자 세트 = utf8mb4

[mysqld를] 문자셋 클라이언트 악수 = FALSE 문자셋 서버 = utf8mb4 기본 문자 세트 기음 ollation-server = utf8mb4_unicode_ci

-mysql.cnf. 나는 터미널에서 sudo service mysql restart을 입력하여 mysql을 다시 시작하고 내가 MySQL의 명령 줄 인터페이스로 가서 입력하면 확인했다 : SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';이 :

+--------------------------+--------------------+ 
| Variable_name   | Value    | 
+--------------------------+--------------------+ 
| character_set_client  | utf8mb4   | 
| character_set_connection | utf8mb4   | 
| character_set_database | utf8mb4   | 
| character_set_filesystem | binary    | 
| character_set_results | utf8mb4   | 
| character_set_server  | utf8mb4   | 
| character_set_system  | utf8    | 
| collation_connection  | utf8mb4_unicode_ci | 
| collation_database  | utf8mb4_unicode_ci | 
| collation_server   | utf8mb4_unicode_ci | 
+--------------------------+--------------------+

내가 무엇을 얻을 수 있습니다.
또한 com.mysql.jdbc_5.1.5.jar을 mysql-connector-java-5.1.44-bin.jar으로 바꿨습니다.

그리고 여전히 DB에 액세스하려고 할 때마다 위의 오류가 발생합니다. 나는 내가 붙어 지점에 도착 생각

최대 절전 모드 XML 구성 파일이 시도 : 나를 utf8mb4에 UTF8에서 업그레이드하는

db.url=jdbc:mysql://localhost:3306/db_name?useUnicode=true&character_set_server=utf8mb4

위의 변화가 충분히 있었다 다음과 같이

이 
<property name="hibernate.connection.CharSet">utf8mb4</property> 
<property name="hibernate.connection.characterEncoding">utf8</property‌​> 
<property name="hibernate.connection.useUnicode">true</property>

또한 연결 URL을 변경 charset scheme.

보조 노트로 은 MySQL이 지원하는 문자 집합 인 반면 UTF8은 문자 인코딩임을 명확히 설명하고 싶습니다. UTF8MB4는 UTF8의 상위 집합입니다. 자세한 내용은 다음 링크를 참조하십시오. https://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html
