JavaEE JTA UserTransaction 여러 테이블에 데이터 삽입

Java EE & JBoss7.1의 다중 테이블 (MySQL)에 데이터를 삽입하는 방법. 필자는 몇 가지 간단한 튜토리얼을 만들었지 만 이제는 하나의 테이블을 가진 빈 파일을 만들었고 데이터를 추가 한 파일 메서드에서 EntityManager에서 데이터를 추가했지만 지금은 관계가있는 많은 테이블을 사용하고 싶습니다. 내가 원하는 간단한 예제를 추가합니다.JavaEE JTA UserTransaction 여러 테이블에 데이터 삽입

내 테이블 (클래스) JPA 2.0을 사용하여 생성되었습니다.

한 번에 두 테이블을 업데이트 할 수 없습니다.

vars를 proc에 전달하여 데이터베이스 프로 시저를 만들 수도 있습니다.

트랜잭션을 사용하면 업데이트 결과를 확인하고 다음 업데이트로 넘어갈 수 있습니다. 하나가 실패하면 롤백 할 수 있으며 변경 사항이 적용되지 않습니다.

MySql은 이것을 지원하지만 올바른 설정과 데이터베이스 [InnoDB]를 사용해야합니다.

START TRANSACTION; 업데이트 테이블 한 세트 x = bla; 오류 롤백 일 경우 업데이트 테이블 2 세트 y = bla; 오류 롤백 else commit 인 경우 ; 단지 예를 들어 당신은 자바에이를 작성하거나 더 나은 수 있습니다

내가 원한다면, 일반적으로, 사용자 테이블에있는 사용자 이름, 암호, 사용자 테이블 및 UserRole 테이블에 다음과 같이 작성해야합니다. 이름, 사용자 역할, user_id는 사용자 테이블의 ID와 동일하지만 나는이 계급 간의 관계를 이해하지 못한다. – Wojtek

Okey, 나는 UserTransaction을 시도했지만 여전히 작동하지 않습니다. – Wojtek

JavaEE JTA UserTransaction 여러 테이블에 데이터 삽입
