springboot集成zipkin

一：下载zipkin

Docker:

docker run -d -p 9411:9411 openzipkin/zipkin

linux

wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec'

linux:

访问测试

localhost:9411

二：spring配置文件集成

1.导入jar包

在pom文件中添加：

<!-- zipkin-->
<dependency>
    <groupId>io.zipkin.brave</groupId>
    <artifactId>brave-core</artifactId>
    <version>3.10.0</version>
</dependency>
<dependency>
    <groupId>io.zipkin.brave</groupId>
    <artifactId>brave-spancollector-http</artifactId>
    <version>3.10.0</version>
</dependency>
<dependency>
    <groupId>io.zipkin.brave</groupId>
    <artifactId>brave-web-servlet-filter</artifactId>
    <version>3.10.0</version>
</dependency>
<dependency>
    <groupId>io.zipkin.brave</groupId>
    <artifactId>brave-okhttp</artifactId>
    <version>3.10.0</version>
</dependency>
<!-- zipkin-->

2.在配置文件中书写参数

##########请求的项目名##########
server.servlet.context-path=/


##########zipKin################
zipkin.serviceName=bbscontent
zipkin.url=http://47.93.136.21:9411
zipkin.connectTimeout=6000
zipkin.readTimeout=6000
zipkin.flushInterval=1
zipkin.compressionEnabled=true

3.添加配置类

package com.jfbank.discuz.config;

import com.github.kristofa.brave.Brave;
import com.github.kristofa.brave.EmptySpanCollectorMetricsHandler;
import com.github.kristofa.brave.Sampler;
