SpringBoot 수동 트랜잭션 관리

springboot 사무 오픈 및 수동 제출
서비스 클래스에 두 개의 주석을 추가해야 한다
@Autowired DataSourceTransactionManager dataSourceTransactionManager; @Autowired TransactionDefinition transactionDefinition;
트랜잭션 TransactionStatus transactionStatus = dataSourceTransactionManager를 수동으로 엽니다.getTransaction(transactionDefinition); 트랜잭션 데이터 SourceTransactionManager를 수동으로 커밋합니다.commit(transactionStatus);//수동 롤백 트랜잭션 데이터 SourceTransactionManager를 커밋합니다.rollback(transactionStatus);//가장 좋은 것은catch에 넣어서 프로그램의 이상을 방지하고, 업무가 어디에 계속 걸려서 제출되지 않는 것을 방지하는 것이다
