## 一、Sleuth 是什么 ##

所以就有了 `Spring Cloud Sleuth` ，并且提供了一套完整的服务跟踪的解决方案。

## 二、环境搭建 ##

首先需要下载 `zipkin` ，地址是：[https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/][https_dl.bintray.com_openzipkin_maven_io_zipkin_java_zipkin-server]。

下载之后进入目录执行 `java -jar .\zipkin-server-2.12.9-exec.jar`：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzk0MTM2NA_size_16_color_FFFFFF_t_70_pic_center 1][]  
然后本地访问 [http://localhost:9411/zipkin/][http_localhost_9411_zipkin] 。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzk0MTM2NA_size_16_color_FFFFFF_t_70_pic_center 2][]  
就可以看到控制台。

--------------------

然后我们就可以在本地搭建链路监控了。

首先引入依赖：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zipkin</artifactId>
    </dependency>

然后配置 `yml` ：

spring:
      application:
        name: cloud-payment-service
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
        username: root
        password: root
        driver-class-name: com.mysql.cj.jdbc.Driver
      zipkin:
        base-url: http://localhost:9411
      sleuth:
        sampler:
          probability: 1
