包路径：io.opencensus.trace.Tracing
类名称：Tracing

Tracing介绍

[英]Class that manages a global instance of the TraceComponent.
[中]类，该类管理TraceComponent的全局实例。

 // 4. Create a scoped span, a scoped span will automatically end when closed.
 // It implements AutoClosable, so it'll be closed when the try block ends.

 // 5. Gracefully shutdown the exporter, so that it'll flush queued traces to Jaeger.
