修改eureka-client-zipkin 项目添加rabbitMQ 依赖

<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-stream-binder-rabbit</artifactId>
		</dependency>

增加配置：

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.password=guest
spring.rabbitmq.username=guest
 
 
# zipkin链接方式
spring.zipkin.sender.type=rabbit
#是否启动zipkin，默认为true
spring.zipkin.enabled=true
# 支持通过服务发现来定位host name：
spring.zipkin.locator.discovery.enabled=true
 

重新启动项目eureka-client-zipkin。

使用 以下命令重新启动zipkin-server-xxx.jar :

 java -jar zipkin-server.jar --STORAGE_TYPE=mysql --MYSQL_DB=springboot --MYSQL_USER=root --MYSQL_PASS=000000 --MYSQL_HOST=localhost --MYSQL_TCP_PORT=3306
 

请求：http://localhost:8788/main  返回8792

查看数据库表

zipkin_annotations表中数据如下：

zipkin_dependencies表数据为空，不清楚原因，知道的朋友解释下。

zipkin_spans表中数据ruxi如下：

关闭eureka-client，再次请求上边链接，请求失败。但是数据库中没有增加记录，目前也不太清楚为什么，需要进一步研究一下，知道的 朋友huan欢迎留言交流。
