This article focuses on "how to solve the sleuth TraceFeignClient SpanName problem of java". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve the sleuth TraceFeignClient SpanName problem of java.

@ Override public Response execute (Request request, Request.Options options) throws IOException {String spanName = getSpanName (request); Span span = getTracer () .createSpan (spanName); if (log.isDebugEnabled ()) {log.debug ("Created new Feign span" + span) } try {AtomicReference feignRequest = new AtomicReference (request); this.spanInjector.inject (span, feignRequest); span.logEvent (Span.CLIENT_SEND); addRequestTags (request); Request modifiedRequest = feignRequest.get () If (log.isDebugEnabled ()) {log.debug ("The modified request equals" + modifiedRequest);} Response response = this.delegate.execute (modifiedRequest, options); logCr (); return response } catch (RuntimeException | IOException e) {logError (e); throw e;} finally {closeSpan (span);}} private String getSpanName (Request request) {URI uri = URI.create (request.url ()) Return uriScheme (uri) + ":" + uri.getPath ();}

The default is to generate spanName based on uri. If it is restful style, / getuser/1 / getuser/2 is 2 span.

Span is generally an operation. For example, getuser. Parameters 1. Tag should be 1.

If you want to change the default uri to span.

Option 1:

1. By adding the Headers annotation @ Headers ({"Content-Type: application/json", "Accept: application/json", Accept {contentType}}) @ PostMapping (value = "/ card-blank/batch-create") Response batchCreateCard (@ RequestBody CreateCardBlankDTO condition,@Param ("contentType") String type) directly on the request or on the class

two。 Override the getspan method to get the spanName from the request header

Option 2:

You can know the feignclient java method called by the current feign, and get the method name as spanName

Override the getspan method to get the spanName from the request header

At this point, I believe you have a deeper understanding of "how to solve the sleuth TraceFeignClient SpanName problem of java". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
