版本要求
SpringBoot、OpenFeign和Zipkin都要求2.1.*
核心代码
- jar包引入

- 相关配置
spring:
cloud:
nacos:
discovery:
server-addr: 10.211.55.16:8848
#feign客户端的命名必须使用中划线,不能使用下划线
application:
name: zipkin-user-service
zipkin:
base-url: http://127.0.0.1:9411/
###全部采集
# 抽样率,默认是0.1(90%的数据会被丢弃)
# 这边为了测试方便,将其设置为1.0,即所有的数据都会上报给zipkin
sleuth:
sampler:
probability: 1.0
效果展示
a、成功链路信息:
- 项目中获取链路信息:
request.getHeader("X-B3-TraceId")+",spanid:"+ request.getHeader("X-B3-SpanId")
-
每一个都是服务端,如果调用其他的话会有客户端的链路
b、失败链路信息:
- 错误信息里可以看到具体的错误
"tags": {
"error": "Request processing failed; nested exception is java.lang.ArithmeticException: / by zero",
"http.method": "GET",
"http.path": "/sendmsg",
"mvc.controller.class": "MsgServiceImpl",
"mvc.controller.method": "sendMsg"
},
