zipkin的数据存储可以存在4个地方:
(基于 第二十八章 springboot + zipkin(brave定制-AsyncHttpClient))
1、pom.xml
io.zipkin.brave
brave-mysql
3.9.0
2、ZipkinConfig添加如下
@Bean
public MySQLStatementInterceptorManagementBean mySQLStatementInterceptorManagementBean(Brave brave) {
return new MySQLStatementInterceptorManagementBean(brave.clientTracer());
}
1、建库
2、建表
mysql.sql位置:https://github.com/openzipkin/zipkin/blob/master/zipkin-storage/mysql/src/main/resources/mysql.sql
或者直接将整个zipkin项目克隆下来,再进去看内容。
mysql.sql内容如下:
CREATE TABLE IF NOT EXISTS zipkin_spans (

`id` BIGINT NOT NULL,

ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT 'Ignore insert on duplicate';

CREATE TABLE IF NOT EXISTS zipkin_dependencies (
`day` DATE NOT NULL,

`child` VARCHAR(255) NOT NULL,

ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);
执行脚本之后,数据库出现三张表,如下:
启动4个service,然后swagger测试,最后查看zipkin和数据库表即可。
