Spring Cloud Sleuth 服务跟踪 将跟踪信息存储到数据库

参见上一篇博客：Spring Cloud Sleuth 服务跟踪

参考：zipkin使用mysql保存数据

主要在跟踪服务上配置：

在数据库创建数据库表：（可不创建，在classpath中添加对应的sql文件也可，有效率问题，详细上面链接文章）

pom.xml 添加如下配置：

<!-- zipkin storage mysql. -->
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-storage-mysql</artifactId>
    <version>2.4.1</version><!-- 此版本与zipkin版本对应 -->
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- 这是mysql驱动，如果自己配置也行，加这个依赖也行 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<!--/ zipkin storage mysql. -->

　　

配置：

server:
  port: 9411
spring:
  datasource:
    schema: classpath:/mysql.sql # 已经存在数据库及其表，则可不写
    url: jdbc:mysql://localhost:3306/zipkin
    username: root
    password: root
# Switch this on to create the schema on startup:
    initialize: true
    continueOnError: true
  sleuth:
    enabled: false
zipkin:
  storage:
    type: mysql

　　

在启动类添加数据源驱动：

package com.thunisoft.maybeesleuthcenter;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import zipkin.server.EnableZipkinServer;
import zipkin.storage.mysql.MySQLStorage;
 
import javax.sql.DataSource;
 
@EnableZipkinServer
@SpringBootApplication
public class MaybeeSleuthcenterApplication {
 
	public static void main(String[] args) {
		SpringApplication.run(MaybeeSleuthcenterApplication.class, args);
	}
 
	@Bean
	public MySQLStorage mySQLStorage(DataSource datasource) {
		return MySQLStorage.builder().datasource(datasource).executor(Runnable::run).build();
	}
}
