Question

我正在使用Spring Data Jpa和hibernate。我有一个扩展JpaRepository的存储库，我用它来将记录保存到数据库中。但是当我调用.flush（）时，会发生以下错误。

我已经看到了其他类似错误的问题，但在尝试在存储库中使用@Transaction之后，我也遇到了同样的错误。

存储库

@Repository
@Transactional
public interface AttributeRepository extends JpaRepository<Attribute, Long> {
    Attribute findById(long id);
}

我的配置包含实体管理器工厂和JPA所需的平台事务管理器，

@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（）方法的服务，

@Service
public interface FeatureService {

    @Transactional
    public List<Feature> rankFeatures(Instances data, List<String> entrezIds, Dataset d);
}

添加，我正在使用@Autowired将存储库注入服务的实现。

Answer 1

使用@Transactional注释您的存储库无济于事;您必须使用@Transactional注释服务方法。 “服务方法”表示封装两者的方法，调用repo的save方法和flush调用。

Answer 2

我认为您忘记启用Jpa Transaction或将Spring Data与事务管理器关联：

Ex启用事务管理：

@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)

Ex将事务管理器与Jpa存储库关联：

@EnableJpaRepositories(transactionManagerRef="transactionManager", 
    entityManagerFactoryRef="entityManagerFactory", 
    value="com.repositories.pkg.location" )

Answer 3

我解决了。我的配置文件分为2个类，一个用于Application Context，另一个用于Persistence Context。我把他们两个结合起来，错误就消失了。

JpaRepository：没有正在进行的事务
