zipkin使用mysql保存数据

zipkin和mysql结合保存zipkin在项目监控中得到的所有数据。

			<artifactId>zipkin-server</artifactId>
		</dependency>
		<!-- 我的zipkin版本是1.19.0，所以zipkin-storage-mysql也是1.19.0.前面改到版本比较高的，1.26.0就一直报错。所以版本要匹配好 -->

			<groupId>io.zipkin.java</groupId>
		    <artifactId>zipkin-storage-mysql</artifactId>
		    <version>1.19.0</version>

		<!-- 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>

　　bootstrap.yml 省略部分配置，放到配置中心也行,

schema: classpath:/mysql.sql配置在数据库创建完以后，可以删除，不然每次都会寻找这个sql，耗费时间。

spring:
  rabbitmq:
    host: ${RABBIT_HOST:localhost}
  datasource:
    schema: classpath:/mysql.sql
    url: jdbc:mysql://${MYSQL_HOST:localhost}/test
    username: root
    password: root
# Switch this on to create the schema on startup:
    initialize: true
    continueOnError: true
sleuth:
    enabled: false
zipkin:
  storage:
    type: mysql
