【问题描述】:
我正在使用 Spring Data Jpa 和 hibernate。我有一个扩展 JpaRepository 的存储库,我正在使用它将记录保存到数据库中。但是当我调用 .flush() 时,出现以下错误。
我看到其他问题有类似的错误,但在存储库中也尝试使用 @Transaction 后,我得到了同样的错误。

存储库
@Repository
@Transactional
public interface AttributeRepository extends JpaRepository<Attribute, Long> {
Attribute findById(long id);
}
我的配置包含 JPA 需要的实体管理器工厂和平台事务管理器,
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(BoneCPDataSource ds) throws IOException {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(ds);
em.setPackagesToScan(new String[] { "org.scripps.branch.entity" });
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(additionalProperties());
return em;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
@Bean
public PlatformTransactionManager transactionManager(
EntityManagerFactory emf) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
调用saveandFlush()方法的Service,
@Service
public interface FeatureService {
@Transactional
public List<Feature> rankFeatures(Instances data, List<String> entrezIds, Dataset d);
}
补充一下,我将使用 @Autowired 的存储库注入到服务的实现中。
【问题讨论】:

是的,我有注释。我可以使用存储库检索对象,但无法保存和刷新实体。
