微服务a方法上面添加注解

@SpringBootApplication
@EnableFeignClients
@EnableAsync
@MapperScan("com.risk.test.mapper")
@EnableTransactionManagement //该注解主要注意 调用分布式事务时要
@EnableCaching
public class AServiceApplication{..

 @LcnTransaction
   @Transactional(rollbackFor = Exception.class)
   @Override
   public List luckDraw(Long userId, GamePrizeDTO gamePrizeDTO, String price) throws CustomExcpion{...

如果微服务A方法内有调用别的微服务的方法时 被调用的微服务B的方法上也需要注释
