作者在springCloud客户端中的RestTemplateConfiguration自定义Feign.Builder拦截Feign请求传递GroupId，这与开启hystrix冲突,feign开启hystrix后，定义了SleuthHystrixFeignBuilder，Feign.Builder全局只能有一个。
解决方法：改用bean的方式添加自定义的RequestInterceptor
然后发现事务参与者获取RequestContextHolder.getRequestAttributes()为null
原因：RequestContextHolder是一个threadlocal变量，事务参与者是新开线程执行的，传递不过去，需要在ActorTxTransactionHandler中传递一下RequestContextHolder
