引起：javax.persistence.TransactionRequiredException：执行更新/删除查询

Question

我正在使用JSpring和JPA / Hibernate开发一个项目。 我尝试调用本机查询来更新数据库。 这是错误跟踪：

我的DAO课程

public class daoImpl implements Idao,Serializable {

String BDD_REF="r_multi_4";

private static final Logger logger = Logger.getLogger(daoImpl.class);

 @PersistenceContext(unitName="ncrm_extraction")
    EntityManager em;


 @PersistenceContext(unitName="BpaProduciton")
    EntityManager emBpa;



 @Transactional
    public int UpdateExt(String pk_obj_id_Rem,String Req) {
        logger.debug("@@@ DAO : Modifier le flag EXT table  remise : "+pk_obj_id_Rem );
        Query q = emBpa.createNativeQuery(Req);
//      q.setParameter("Date", dteTr);
//      q.setParameter("pk_obj_id_Rem", pk_obj_id_Rem);

        int flag=q.executeUpdate();


        return flag;
    }

我的坚持：

        <!-- <class>com.ncrm.dao.entities.user</class> -->

    </persistence-unit> 

    <persistence-unit name="BpaProduciton" transaction-type="RESOURCE_LOCAL">
        <!-- <class>com.ncrm.dao.entities.user</class> -->
    </persistence-unit>
</persistence>

假设你修改你的DaoImpl如下。

@Modifying(clearAutomatically = true)
@Transactional
public int UpdateExt(String pk_obj_id_Rem,String Req) {
        logger.debug("@@@ DAO : Modifier le flag EXT table  remise : "+pk_obj_id_Rem );
        Query q = emBpa.createNativeQuery(Req);
        int flag=q.executeUpdate();
        return flag;
}

希望这可以帮助。
