Question

我正在创建简单的spring boot应用程序。我使用spring transaction management来处理事务。这是我的代码。

ServiceImpl类

@Service("orderService")
public class OrderServiceImpl implements OrderService {

    @Autowired
    private CustomerDao customerDao;

    @Autowired
    private OrderDao orderDao;

    @Transactional(rollbackFor = Exception.class)
    @Override
    public Long placeOrder(OrderPlacementRequest request) {
      customerDao.save(request.getCustomer());
      return orderDao.placeOrder(request.getOrder());
    }
 }

OrderDaoImpl类，

@Repository("orderDao")
public class OrderDaoImpl extends AbstractHibernateDao implements OrderDao        {

    @Override
    public Long placeOrder(Order order) {
        throw new RuntimeException("Test Error Message");
    }
}

配置类，

@Configuration
@EnableTransactionManagement
public class HibernateConfig {

 //Other Configurations

     @Autowired
     private final Environment environment;

     @Bean
     public DataSource dataSource() {
         DriverManagerDataSource dataSource = new DriverManagerDataSource();
   dataSource.setDriverClassName(environment.getRequiredProperty("spring.datasource.driver-class-name"));
    dataSource.setUrl(environment.getRequiredProperty("spring.datasource.url"));
    dataSource.setUsername(environment.getRequiredProperty("spring.datasource.username"));
    dataSource.setPassword(environment.getRequiredProperty("spring.datasource.password"));
    return dataSource;
}

    @Bean
    public DataSourceTransactionManager transactionManager() {
        DataSourceTransactionManager transactionManager = new DataSourceTransactionManager();
        transactionManager.setDataSource(dataSource());
        return transactionManager;
    }
}

application.properties

spring.aop.proxy-target-class=true

OrderController类

@RestController
@RequestMapping("/order")
public class OrderController {

    @Autowired
    private OrderService orderService;

    @RequestMapping(value = "/place", method = RequestMethod.POST)
    public Long placeOrder(@RequestBody OrderPlacementRequest request) {
        return orderService.placeOrder(request);
    }
}

在我的情况下即使第二种方法placeOrder失败了。客户将保存在mysql数据库中。我想要的是回滚客户保存方法。我阅读了一些关于事务管理的文章，包括spring docs和stackoverflow。仍然找不到问题。

使用Controller类更新。

@Transactional没有使用RuntimeException回滚
