How to access Span and Baggage item in Java?

[gvkarthik93]

I have a client-server architecture. Microservice A is building a span using the following code and sending request to Microservice B.

@RequestMapping("/chaining") public String chaining() { Span span = tracer.buildSpan("build-span-test").start(); span.setBaggageItem("baggage-key", "baggage-value"); span.close(); ResponseEntity<String> response = restTemplate.getForEntity("http://localhost:8092/receive", String.class); return "Chaining + " + response.getBody(); }

Now how can I access this span and baggage on Microservice B?

Following is the code I have for Microservice B:

@RequestMapping("/receive") String testhome(@RequestHeader HttpHeaders headers) { return "Response from Server"; }

I tried buldspan but it's building new span. Can you please tell me what I need to put in this code to access the span and baggage built on Microservice A in the Microservice B?
