In this way, with the addition of two configuration items and no changes to one line of code, we started the distributed call chain tracking function based on Zipkin and Java chassis.
**Note **If other dependencies in the project also introduce a zipkin (such as Spring Cloud), which may cause the zipkin version to be inconsistent and run incorrectly, you need to declare the zipkin version in the project pom.
+
+### Providing the full http.path
+
+The default http.path returned by Java Chassis is the operation path, which is different from the path of other frameworks. You can return the full http.path as follows.
+
+Setting the value of servicecomb.tracing.workWithThirdParty to true in the file of micoservice.yaml.
+
+```
+ servicecomb:
+ handler:
+ chain:
+ Consumer:
+ default: loadbalance,tracing-consumer
+ Provider:
+ default: tracing-provider
+ tracing:
+ workWithThirdParty: true
+```

**注意 **如果项目中的其他依赖也引入了 zipkin （例如 Spring Cloud），可能导致 zipkin 版本不一致而运行出错，这时需要在项目 pom 中声明 zipkin 版本。
+### 提供完整的http.path
+
+由于Java Chassis中默认返回的http.path是operation路径，相较于其他框架的路径区别较大，可以通过下述方式，返回完整的http.path
+
+在microservice.yaml文件中设置配置项：servicecomb.tracing.workWithThirdParty的值为true
+
+```
+ servicecomb:
+ handler:
+ chain:
+ Consumer:
+ default: loadbalance,tracing-consumer
+ Provider:
+ default: tracing-provider
+ tracing:
+ workWithThirdParty: true
+```
