存储跟踪数据
Zipkin Server默认时间追踪数据信息保存到内存，这种方式不适合生产环境。因为一旦Service关闭重
启或者服务崩溃，就会导致历史数据消失。Zipkin支持将追踪数据持久化到mysql数据库或者存储到
elasticsearch中。这里已mysql为例。
准备数据库
可以从官网找到Zipkin Server持久mysql的数据库脚本。

基于消息中间件收集数据
在默认情况下，Zipkin客户端和Server之间是使用HTTP请求的方式进行通信（即同步的请求方式），在
网络波动，Server端异常等情况下可能存在信息收集不及时的问题。Zipkin支持与rabbitMQ整合完成异
步消息传输。
加了MQ之后，通信过程如下图所示：

 服务端启动

客户端配置
（1） 配置依赖

<!--sleuth链路追踪-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>
<!--zipkin依赖-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
</dependency>

导入 spring-rabbit 依赖，是Spring提供的对rabbit的封装，客户端会根据配置自动的生产消息并发送
到目标队列中
（2） 配置消息中间件rabbit mq地址等信息

spring:
  zipkin:
      # base-url:  http://192.168.180.137:9411/
      sender:
        #type: web
        type: rabbit
    sleuth:
      sampler:
        probability: 1.0
    rabbitmq:
      host: 192.168.180.137
      port: 5672
      username: guest
      password: guest
      listener: # 这里配置了重试策略
        direct:
          retry:
            enabled: true
        simple:
          retry:
          enabled: true

修改消息的投递方式，改为 rabbit即可。
添加 rabbitmq的相关配置
（3） 测试
关闭Zipkin Server，并随意请求连接。打开rabbitmq管理后台可以看到，消息已经推送到rabbitmq。
当Zipkin Server启动时，会自动的从rabbitmq获取消息并消费，展示追踪数据
可以看到如下效果：
请求的耗时时间不会出现突然耗时特长的情况
当 ZipkinServer不可用时（比如关闭、网络不通等），追踪信息不会丢失，因为这些信息会保存在
Rabbitmq服务器上，直到Zipkin服务器可用时，再从Rabbitmq中取出这段时间的信息
