Tracing.propagationFactory介绍

[英]This supports edge cases like GRPC Metadata propagation which doesn't use String keys.
[中]这支持边缘情况，比如不使用字符串键的GRPC元数据传播。

代码示例

/**
 * When a trace leaves the process, it needs to be propagated, usually via headers. This utility
 * is used to inject or extract a trace context from remote requests.
 */
// Implementations should override and cache this as a field.
public Propagation<String> propagation() {
 return propagationFactory().create(Propagation.KeyFactory.STRING);
}

代码示例来源：origin: openzipkin/brave

GrpcTracing(Builder builder) { // intentionally hidden constructor

 Propagation.Factory propagationFactory = tracing.propagationFactory();

  propagationFactory = GrpcPropagation.newFactory(propagationFactory);
 }
 propagation = propagationFactory.create(AsciiMetadataKeyFactory.INSTANCE);

}
