Tracer.startRequestWithRootSpan介绍

[英]Starts new span stack (i.e. new incoming request) without a parent span by creating a root span with the given span name. If you have parent span info then you should call #startRequestWithChildSpan(Span,String) or #startRequestWithSpanInfo(String,String,String,boolean,String,SpanPurpose) instead). The newly created root span will have a span purpose of SpanPurpose#SERVER.

NOTE: This method will cause the returned span's Span#getUserId() to contain null. If you have a user ID you should use #startRequestWithRootSpan(String,String) instead.

WARNING: This wipes out any existing spans on the span stack for this thread and starts fresh, therefore this should only be called at the request's entry point when it's expected that the span stack should be empty. If you need to start a child span in the middle of a request somewhere then you should call #startSubSpan(String,SpanPurpose) instead.
[中]通过使用给定的跨距名称创建根跨距，在没有父跨距的情况下启动新的跨距堆栈（即新的传入请求）。如果您有父span信息，那么您应该调用#startRequestWithChildSpan（span，String）或#startrequestwithspan信息（String，String，String，boolean，String，SpanPurpose）。新创建的根span的span purpose为span purpose#SERVER。
注意：此方法将导致返回的span的span#getUserId（）包含null。如果您有用户ID，则应使用#startRequestWithRootSpan（String，String）。
警告：这将清除该线程的跨度堆栈上的所有现有跨度，并重新开始，因此，只有在预期跨度堆栈应为空时，才应在请求的入口点调用它。如果您需要在某个请求的中间启动一个子跨度，那么您应该调用SysString子String（String，SabVAIL）。
