스프링 부팅 : javax.persistence.TransactionRequiredException : 업데이트 / 삭제 쿼리 실행

Question

스프링 부팅을 사용하고 다음과 같이 내 응용 프로그램을 구성하고 있습니다.

@Configuration
@EnableAutoConfiguration
@EnableTransactionManagement
@ComponentScan
@EntityScan("ch.xy.model")
public class Application {

    @Autowired
    private ImportDAO importDao;

}

.

importdao는 그 것처럼 보입니다 :

@Repository
public class ImportDAO {

    @PersistenceContext
    private EntityManager em;

    @Transactional
    void removeTempoAccounts() {
        Query q = em.createQuery("DELETE FROM TempoAccount t WHERE t.manual = false");
        q.executeUpdate();
    }
}

.

그러나 removeTempoAcconts가 실행될 때 i :

.

내 구성이 무엇이 잘못 되었습니까?

Answer 1

@Transactional
void removeTempoAccounts() {

.

방법에는 기본 가시성이 있습니다.그러므로 프록시 메커니즘이 활성화되지 않았습니다! Public everthing으로 변경 한 후 예상대로 작동합니다!

Answer 2

스프링 패키지에서 @Transactional 주석을 사용해보십시오. @org.springframework.transaction.annotation.Transactional처럼 그런 다음

가 작동해야합니다
