springboot消费kafka设置topics 以及 groupId

关于kafka的这些概念和理论请见这篇博客 https://www.jianshu.com/p/d3e963ff8b70，

在下只简单阐述一下自己遇到的问题以及解决办法  由于之前自己配置的maven版本和消费kafka信息的姿势有问题，所以导致上线时疯狂报错：Attempt to join group failed due to fatal error: The configured groupId is i  xxx

现贴上正确的使用套路    上maven  这里要注意的是  如果你kafka配置jar包不指定版本，那么默认会追随springboot的版本，所以当你使用低版本的springboot的时候建议带上版本号

指定topics 以及 groupId 只要在方法的注解上标示就好了，但是问题是，假设你的jar包版本有问题的话是没有groupid这个选项的，它会报错，所以得注意下jar包的版本
