X-B3-SpanId常数在哪里定义？

[英]Where is X-B3-SpanId constant defined?

原文 2019-06-14 19:02:58 5 1 java/ spring-cloud-sleuth/ brave

In https://static.javadoc.io/org.springframework.cloud/spring-cloud-sleuth-core/1.2.0.RELEASE/org/springframework/cloud/sleuth/Span.html#SPAN_ID_NAME there's a constant for X-B3-SpanId but that constant does not appear to be in spring-cloud-sleuth-core-2.1.0.RELEASE.jar 在https://static.javadoc.io/org.springframework.cloud/spring-cloud-sleuth-core/1.2.0.RELEASE/org/springframework/cloud/sleuth/Span.html#SPAN_ID_NAME中， X-B3-SpanId有一个常数X-B3-SpanId但该常量似乎不在spring-cloud-sleuth-core-2.1.0.RELEASE.jar

Is there a new place for that constant? 有没有这个常数的新地方？

1 个解决方案

With Sleuth 2.0 we've migrated to Brave ( https://github.com/apache/incubator-zipkin-brave ) as the new Tracer library. 借助Sleuth 2.0，我们已迁移到Brave（ https://github.com/apache/incubator-zipkin-brave ）作为新的Tracer库。 The new place for that constant is here https://github.com/apache/incubator-zipkin-brave/blob/v5.6.4/brave/src/main/java/brave/propagation/B3Propagation.java but mind you that it's a package scope value. 该常量的新位置在这里https://github.com/apache/incubator-zipkin-brave/blob/v5.6.4/brave/src/main/java/brave/propagation/B3Propagation.java，但请注意，它是包范围值。 Which means that you have to define your own constant. 这意味着您必须定义自己的常量。 You can however retrieve it via the https://github.com/apache/incubator-zipkin-brave/blob/9fc4a977aba15c5af7a4bacddaf4d7f7267a663a/brave/src/main/java/brave/propagation/B3Propagation.java#L81 keys method. 但是，您可以通过https://github.com/apache/incubator-zipkin-brave/blob/9fc4a977aba15c5af7a4bacddaf4d7f7267a663a/brave/src/main/java/brave/propagation/B3Propagation.java#L81 keys方法进行检索。

哪个记录 X-B3-SpanId 或 SpanId？ X-B3-TraceId 还是 TraceId？（春天的侦探） - Which to log X-B3-SpanId or SpanId? X-B3-TraceId or TraceId? (Spring sleuth)

测试X = A，B或C. - Test if X = A, B or C

在返回语句中具有常量变量的三元运算符。返回a> b？a：b +1; 或返回1 + a> b？a：b; - Ternary operator with constant variable in return statement. return a>b?a:b + 1; or return 1 + a>b?a:b;
