spring boot 多数据源，子事务不生效

@Primary
@Bean(name = "primaryTransactionManager")
public DataSourceTransactionManager transactionManager(@Qualifier("primaryDataSource") DataSource dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

@Bean(name = "secondTransactionManager")
public DataSourceTransactionManager transactionManager(@Qualifier("secondDataSource") DataSource dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

@RequestMapping(value = "add", method = RequestMethod.POST)
@ResponseBody
@Transactional(rollbackFor = Exception.class)
public BaseResponse add() {
    BaseResponse response = new BaseResponse(StatusCode.Success);

    User user = new User();
    user.setName("张三");
    user.setCode("10010");
    userMapper.insertSelective(user);

    SysConfig sysConfig = new SysConfig();
    sysConfig.setName("颜色");
    sysConfigMapper.insertSelective(sysConfig);
     int i = 1/0;
    return response;
}

发生异常后，子事务不会进行回滚

如果没有看过源码，不熟悉事务流程，分布式事务是解决这个问题的最简单的方式！

麻烦问下题主 解决了么 怎么解决的 谢谢
