SpringCloud2.0 zipkin简单demo

*  ## 简介 ##

Zipkin是一个分布式跟踪系统，Sleuth负责为服务之间的调用提供链路追踪，而Zipkin用于收集在微服务体系结构中延迟问题排除所需的定时数据。通俗来说就是收集各微服务应用的接口调用过程所消耗的时间数据，方便开发人员快速定位解决接口性能问题。

*  ## 相应依赖 ##

spring-cloud-starter-zipkin中已包含了spring-cloud-starter-sleuth与spring-cloud-sleuth-zipkin的依赖，所以使用sleuth-zipkin的SpringCloud项目只需添加spring-cloud-starter-zipkin依赖即可

*  ## 快速开始 ##

          sleuth:
            sampler:
              probability: 1.0   #2.0后percentage改为probability

###### 执行结果 ######

访问消费者接口http://localhost:9999/index，在刷新zipkin页面便可发现consumer服务已添加到Service Name选择框，点击下侧服务名上的蓝色框即可查看该次接口调用的详细信息。  
注:若不调用相应接口对应的服务名不会显示到选择框，一开始还以为自己配置错了。
