SpringCloud的学习记录(8)

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:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
server:
  port: 8766
spring:

      exposure:
        include: '*'
  metrics:
    web:
      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,
  `id` BIGINT NOT NULL,
  `name` VARCHAR(255) NOT NULL,
  `parent_id` BIGINT,
  `debug` BIT(1),
  `start_ts` BIGINT COMMENT 'Span.timestamp(): epoch micros used for endTs query and to implement TTL',
  `duration` BIGINT COMMENT 'Span.duration(): micros used for minDuration and maxDuration query'
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;

) 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';

CREATE TABLE IF NOT EXISTS zipkin_dependencies (

  `child` VARCHAR(255) NOT NULL,
  `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:
