**一 开源项目地址**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch][https_github.com_cakin24_spring-cloud-code_tree_master_ch]16-1

**二 测试**

1 启动ch16-1-sleuth-provider

2 启动ch16-1-sleuth-consumer

3 在浏览器输入： [http://localhost:8081/helloByFeign?name=cakin][http_localhost_8081_helloByFeign_name_cakin]

控制台输出：

6 说明

从上面输出可知：引入spring-cloud-sleuth之后，首先我们的日志组件可以自动打印Span信息，然后Span信息不仅可以随着feign、restTemplate往服务端传递，还可以在父子线程之间传递。
