说明

这个功能全部在消费者上，如user，pc

Sleuth

1.添加依赖

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

2.application.yml添加日志级别，在spring下

logging:
  level:
    root: INFO
    org.springframework.web.servlet.DispatcherServlet: DEBUG
    org.springframework.cloud.sleuth: DEBUG

3.程序运行，接口调用后，控制是这样子

其中 6d9f31c3491e762c是TraceId，后面跟着的是SpanId，依次调用有一个全局的TraceId，将调用链路串起来
这样子难观察，难记录，所以要使用Zipkin

Zipkin

从spring boot 2.0开始，官方就不再支持使用自建Zipkin Server的方式进行服务链路追踪，而是直接提供了编译好的 jar 包来给我们使用

这里提供zipkin-server-2.12.9的包：https://wwba.lanzoum.com/iEVc80pfj8tc

1.添加依赖

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

2.配置文件，在spring下

  zipkin:
    base-url:  http://127.0.0.1:9411/ #zipkin server的请求地址
    sender:
      type: web #请求方式,默认以http的方式向zk server发送追踪数据
  sleuth:
    sampler:
      probability: 1.0 #采样的百分比

3.运行jar包，注意路径不能有中文

出现r in 3.507 seconds (JVM running for 4.319)，就表示完成

在这里可以看到地址，访问时需要后面手动加/zipkin 完整地址：http://127.0.0.1:9411/zipkin/

4.完成，访问接口后，点击查询，就可以看到收集的信息了

让Zipkin收集的数据，放入mysql

1.数据库脚本

CREATE TABLE IF NOT EXISTS zipkin_spans (
  `trace_id_high` BIGINT NOT NULL DEFAULT 0 COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
  `trace_id` BIGINT NOT NULL,

CREATE TABLE IF NOT EXISTS zipkin_dependencies (

) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;

ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);

2.命令行启动的时，要这样启动

java -jar zipkin-server-2.12.9-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=127.0.0.1 --MYSQL_TCP_PORT=3306 --MYSQL_DB=zipkin --MYSQL_USER=root --MYSQL_PASS=ok
