해결법
-
==============================
1.Spring config에 지정된 트랜잭션 관리자가 있지만, 트랜잭션을 적용 할시기와 위치는 없습니다.
Spring config에 지정된 트랜잭션 관리자가 있지만, 트랜잭션을 적용 할시기와 위치는 없습니다.
SpringBean.xml에서
주석 처리를 제거해야한다. <tx:annotation-driven transaction-manager="transactionManager"/>그런 다음 CustomerServiceImpl.saveCustomer 메서드에 @Transactional이라는 주석을 달아야합니다.
@Service public class CustomerServiceImpl implements CustomerService { ... @Override @Transactional public void saveCustomer(Customer customer) { customerDaoImpl.saveCustomer(customer); } ... } -
==============================
2.Hibernate 4에 대한 hibernate.cfg.xml 파일에 다음 프로퍼티를 추가하십시오.
Hibernate 4에 대한 hibernate.cfg.xml 파일에 다음 프로퍼티를 추가하십시오.
<property name="hibernate.current_session_context_class">thread</property> -
==============================
3.xml을 사용하지 않고 주석을 기반으로 구성한 경우 Java 구성 파일에 @EnableTransactionManagement 주석을 추가하십시오.

이것은 누군가를 도울 수있다.

4.
You can add in hibernate.proerties below value. It's worked for me. hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext또는
hibernate.current_session_context_class = 쓰레드
