类名称：Tracer
方法名：completeRequestSpan

Tracer.completeRequestSpan介绍

[英]Completes the current span by calling #completeAndLogSpan(Span,boolean) on it, empties the MDC by calling #unconfigureMDC(), and clears out the #currentSpanStackThreadLocal stack.

This should be called by the overall request when the request is done. At the point this method is called there should just be one span left on the #currentSpanStackThreadLocal stack - the overall request span. If there is more than 1 then that indicates a bug with the usage of this class where a child span is created but not completed. If this error case is detected then and all spans will be logged/popped and an error message will be logged with details on what went wrong.
[中]通过调用#completeAndLogSpan（span，布尔值）来完成当前span，通过调用#unconfigureMDC（）清空MDC，并清除#currentSpanStackThreadLocal堆栈。
当请求完成时，应该由整体请求调用。在调用此方法时，#currentSpanStackThreadLocal堆栈上应该只剩下一个跨度，即整个请求跨度。如果超过1，则表示该类的使用存在错误，其中创建了一个子跨度，但尚未完成。如果检测到此错误情况，则会记录/弹出所有跨度，并记录错误消息，详细说明出错原因。
