resource = Resource.create({"service.name": "checkout-api"})
provider = TracerProvider(resource=resource)
provider.add_span_processor(
BatchSpanProcessor(OTLPSpanExporter(endpoint="http://otel-collector:4317", insecure=True)))
trace.set_tracer_provider(provider)
tracer = trace.get_tracer("checkout")生产用 BatchSpanProcessor 批量发送；调试期可临时加 ConsoleSpanExporter 打印导出内容。
