demo的哪个工程跑不起来？提示什么错误？你这issue发出来，好像是遇到什么问题了但是啥都没说，然后就直接指责了，你希望达到什么效果？纯粹就是抱怨么？issue区还是尽量有问题说问题吧。

springcloud的demo
1、hosts文件还得改
2、日志也搞不清为啥非得放文件里，直接输出到控制台不行吗？
demo真是不够demo，开箱不能即用

你说的这些，也算不上是代码有问题吧？

springcloud的demo
1、hosts文件还得改
- 早期springcloud发布的demo也需要改hosts，byteTCC的springcloud的样例直接拷贝了这种方式，后续没再调整而已。
2、日志也搞不清为啥非得放文件里，直接输出到控制台不行吗？
- 日志打印在日志文件，这种做法不能理解？这可能算个人喜好问题吧，我本人更喜欢控制台少打印一些无关的信息：byteTCC-sample除了显式打印一些显示业务/确认/取消在进行的信息外，控制台基本上比较清爽。作为demo而言，很方便看到调试效果。
demo真是不够demo，开箱不能即用

开源项目发布出来，是本着一起交流的目的。有好的想法愿意提出来，大家可以一起完善。有问题解决问题，只是没有必要象本issue这样抱有太多负面情绪。

好吧，只能说每个人想法不一样，不过看过源码后，您的代码写的风格还是挺舒服的，对新手来说很友好，只不过demo就不是那么友好了

    application.setBannerMode(Banner.Mode.OFF);
    application.run(args);
    log.info("springboot consumer start success");
  }
}

运行后，调用test HTTP接口，报错了，但是没有触发cancel方法，这是为什么呢？

全局事务回滚情况下，也并非每个TCC服务的cancel都需要被调用。如果byteTCC可以通过本地事务回滚将该服务撤回，后续就不再调用其cancel了。
详细请参考用户指南中"3.3、TCC型服务Cancel业务定义"章节的注意说明。
