이전에는 트랜잭션을 처리 한 getTransaction() 및 commitTransaction() 메소드가있는 BaseDAO를 사용했습니다.Spring - @Transactional이 트랜잭션을 시작하지 않습니다.
package services;
import daos.interfaces.InterfaceEmployerDAO;
import dtos.EmployerDTO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
import services.interfaces.InterfaceEmployerService;
import transformers.interfaces.InterfaceEmployerTransformer;
import java.util.List;
public class EmployerService implements InterfaceEmployerService {
@Autowired
private InterfaceEmployerDAO employerDAO;
@Autowired
private InterfaceEmployerTransformer employerTransformer;
@Override
@Transactional
public List<EmployerDTO> getAllEmployers() {
return employerTransformer.listToDTO(employerDAO.getAllEmployers());
}
(methods irrevelant at this moment)
}
그리고 <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />이 applicationContext.xml에 추가되었습니다 : 나는 게으른 로딩 @OneToMany 관계를 추가 할 때, 나는이 오류 등 어떤 세션과 관련된했다 그래서 난 내 EmployerService 방법에 @Transactional 주석을 사용하기로 결정 파일 (나는 봄 주석의 초보자 그리고 난이 문제를 해결하는 것이 중요 할 수 있는지 모르기 때문에 나는 혼란을 드려 죄송합니다, 모든 붙여 넣기) :

가 나는 것을 생각 HibernateTransactionManager 및 tx:annotation-driven이 작동했지만 잘못되었습니다 - **createCriteria is not valid without active transaction**을 daos.EmployerDAO.getAllEmployers 방법으로 받았습니다. transactionManager을 제대로 구성 할 수 없다고 확신합니다. 아무도 나를 도우 려하지 않으면 매우 기쁠 것입니다. 미리 감사드립니다.

다시 한 번 감사드립니다 어떤 도움 : 가 나는 또한 MVC-디스패처-servlet.xml에 제시, 어쩌면 뭔가 문제가있다.
