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: application: name: zipkin-server sleuth: enabled: false datasource: #schema[0]: classpath:/zipkin.sql url: jdbc:mysql://localhost:3306/zipkin?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8 username: root password: 你的数据库密码 driver-class-name: com.mysql.cj.jdbc.Driver continue-on-error: true #rabbitmq: # host: 127.0.0.1 # port: 5672 # username: guest # password: guest zipkin: storage: type: mysql management: endpoint: health: show-details: always endpoints: web: 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; 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 ( `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 COMMENT 'coincides with zipkin_spans.trace_id', `span_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.id', `a_key` VARCHAR(255) NOT NULL COMMENT 'BinaryAnnotation.key or Annotation.value if type == -1', `a_value` BLOB COMMENT 'BinaryAnnotation.value(), which must be smaller than 64KB', `a_type` INT NOT NULL COMMENT 'BinaryAnnotation.type() or -1 if Annotation', `a_timestamp` BIGINT COMMENT 'Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp', `endpoint_ipv4` INT COMMENT 'Null when Binary/Annotation.endpoint is null', `endpoint_ipv6` BINARY(16) COMMENT 'Null when Binary/Annotation.endpoint is null, or no IPv6 address', `endpoint_port` SMALLINT COMMENT 'Null when Binary/Annotation.endpoint is null', `endpoint_service_name` VARCHAR(255) COMMENT 'Null when Binary/Annotation.endpoint is null' ) 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'; ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`, `span_id`) COMMENT 'for joining with zipkin_spans'; ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTraces/ByIds'; ALTER TABLE zipkin_annotations ADD INDEX(`endpoint_service_name`) COMMENT 'for getTraces and getServiceNames'; ALTER TABLE zipkin_annotations ADD INDEX(`a_type`) COMMENT 'for getTraces'; ALTER TABLE zipkin_annotations ADD INDEX(`a_key`) COMMENT 'for getTraces'; CREATE TABLE IF NOT EXISTS zipkin_dependencies ( `day` DATE NOT NULL, `parent` VARCHAR(255) NOT NULL, `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:
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.
