java – 抛出异常后回滚事务

作者:互联网

当我在服务方法中抛出异常时,我预计服务上的事务注释将回滚保存操作,但它不起作用.

这是我的服务:

  @Service
  @Transactional(value = "transactionManager", rollbackFor = Exception.class)
    public class OrderServiceImp implements OrderService {
        @Autowired
        private OrderRepository orderRepository;

        @Override
        public void doSomeStaff(Long orderId) {
             Order order = orderRepository.findOne(orderId);
             orderRepository.save(order);
             throw new NullPointerException("Test transaction exeption");
        }
    }

在data.xml中,我有下一个配置:

<tx:annotation-driven transaction-manager="transactionManager" />

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>


<jpa:repositories base-package="com.dmitro.repositories" entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager"/>

在dispatcher-servlet.xml中我声明了scan:

<context:component-scan base-package="com.dmitro.service" />

我正在使用spring-data-jpa 1.8.0.RELEASE.请帮忙!

解决方法:

@Transactional(value = "transactionManagerForServiceLayer", rollbackFor = Exception.class)

这是罪魁祸首.您不应该为服务和存储库提供不同的事务管理器.要修复它,您需要将transactionManagerForServiceLayer替换为transactionManager,然后回滚将起作用.
