看了很多资料都依赖的spring-cloud-starter-zipkin，结果版本各种不兼容，其实向zipkin发送信息依赖spring-cloud-sleuth-zipkin即可。
spring-cloud-starter-sleuth: 依赖该包即可打开链路追踪
spring-cloud-sleuth-zipkin: 该包负责向zipkin发送信息

zipkin.base-url: zipkin服务地址端口
zipkin.sender.type: 发送类型，除了web还有一些其他类型。如kafka等。
sleuth.sampler.probability: 0-1的数字，默认0.1。1代表所有请求都被追踪。
logging.level.org.springframework.cloud.sleuth: DEBUG 打开后可看到每次请求的traceId和spanId。
