这一章节讲zipkin-server.

在我们生成的Demo项目上右键点击New->Module->spring Initializr, 然后next, 填写Group和Artifact等信息,

这里Artifact填写zipkinserver, 再次next, 选择内容如下的pom.xml:

在application.yml内容如下:

eureka:

spring:
application:

endpoints:

metrics:

server:
auto-time-requests: false

其中zipkin数据库的sql如下:

CREATE SCHEMA IF NOT EXISTS `zipkin` DEFAULT CHARACTER SET utf8 ;
USE `zipkin` ; 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,

) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci; ALTER TABLE zipkin_spans ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `id`) COMMENT 'ignore insert on duplicate';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`, `id`) COMMENT 'for joining with zipkin_annotations';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTracesByIds';
ALTER TABLE zipkin_spans ADD INDEX(`name`) COMMENT 'for getTraces and getSpanNames';
ALTER TABLE zipkin_spans ADD INDEX(`start_ts`) COMMENT 'for getTraces ordering and range'; CREATE TABLE IF NOT EXISTS zipkin_annotations (

) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci; ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT 'Ignore insert on duplicate';

`call_count` BIGINT
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci; ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);

最后ZipkinServerApplication.java内容如下:

package com.xum.zipkinserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
//import org.springframework.cloud.sleuth.zipkin.stream.EnableZipkinStreamServer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Primary;
import zipkin2.storage.mysql.v1.MySQLStorage;
import zipkin2.server.internal.EnableZipkinServer; import javax.sql.DataSource; @SpringBootApplication
@EnableEurekaClient
@EnableZipkinServer
//@EnableZipkinStreamServer
public class ZipkinServerApplication { public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
} @Bean
@Primary // 把数据存储到数据库中.
public MySQLStorage mySQLStorage(DataSource datasource) {
return MySQLStorage.newBuilder().datasource(datasource).executor(Runnable::run).build();
}
}

在fegin-client和ribbon-consumer的pom.xml中加入如下内容:

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

然后再各自的aplication.yml中加入如下红色内容:

spring:
application:
name: 这里是ribbon-consumer或则是fegin-client
zipkin:
base-url: http://localhost:8766
sleuth:
sampler:
probability: 1.0

顺序启动如下项目:

1. eureka-server

2. config-server

3. eureka-client

4. fegin-client

5. ribbon-consumer

6. zuul-client

7. zipkin-server

浏览器打开地址:http://localhost:8766/zipkin/, 显示如下,

现在用浏览器或则post man 发送一条api: http://localhost:8773/api-b/feign/feignconsumer?name=xum,

然后再zipkin页面中点击查找按钮(可以过滤), 最后根据时间找到刚才发的那条api, 如下图:

点击进去, 全部展开, 可以看到这条api经历的详细信息.

再次点击内容可以看到更详细的信息:

你也可以打开数据库zipkin, 里面保存了刚才发送那条api的信息.
