我使用配置从我的 java 应用程序中成功推送了指标和跟踪以打开遥测收集器

        System.setProperty("otel.resource.attributes", "service.name=OtlpExporterExample");
        System.setProperty("otel.metrics.exporter", "otlp");
        OpenTelemetry openTelemetry = initOpenTelemetry();
        MeterProvider meterProvider = initOpenTelemetryMetrics();
        tracer = openTelemetry.getTracer("io.opentelemetry.example");
        Meter meter = meterProvider.get("io.opentelemetry.example");
        // custom logs here
        LongHistogram recorder = meter.histogramBuilder("super_timer").ofLongs().setUnit("ms").build();
        // sleep for a bit to let everything settle
        Thread.sleep(2000);

辅助方法是

static OpenTelemetry initOpenTelemetry() {
        OtlpGrpcSpanExporter spanExporter =
              OtlpGrpcSpanExporter.builder().setTimeout(2, TimeUnit.SECONDS)
                    .build();
        BatchSpanProcessor spanProcessor =
              BatchSpanProcessor.builder(spanExporter)
                    .setScheduleDelay(100, TimeUnit.MILLISECONDS)
                    .build();

        SdkTracerProvider tracerProvider =
              SdkTracerProvider.builder()
                    .addSpanProcessor(spanProcessor)
                    .setResource(OpenTelemetryResourceAutoConfiguration.configureResource())
                    .build();
        OpenTelemetrySdk openTelemetrySdk =
              OpenTelemetrySdk.builder().setTracerProvider(tracerProvider).buildAndRegisterGlobal();

        Runtime.getRuntime().addShutdownHook(new Thread(tracerProvider::shutdown));

        return openTelemetrySdk;
    }

    /**
     * Initializes a Metrics SDK with a OtlpGrpcMetricExporter and an IntervalMetricReader.
     *
     * @return a ready-to-use {@link MeterProvider} instance
     */
    static MeterProvider initOpenTelemetryMetrics() {
        // set up the metric exporter and wire it into the SDK and a timed reader.
        OtlpGrpcMetricExporter metricExporter = OtlpGrpcMetricExporter.getDefault();

        MetricReaderFactory periodicReaderFactory =
              PeriodicMetricReader.create(metricExporter, Duration.ofMillis(1000));

        SdkMeterProvider sdkMeterProvider =
              SdkMeterProvider.builder()
                    .registerMetricReader(periodicReaderFactory)
                    .buildAndRegisterGlobal();

        Runtime.getRuntime().addShutdownHook(new Thread(sdkMeterProvider::shutdown));
        return sdkMeterProvider;
    }

（我从 github repo 复制了这段代码）

现在我正在尝试将现有的日志记录包装器移动到更改最少的输出范围

    @WithSpan("important")
    public void info(@SpanAttribute("class") Class classObj, @SpanAttribute("message") CustomClass message) {
        System.out.println("Trace id " + Span.current().getSpanContext().getTraceId());
            System.out.println("span id " + Span.current().getSpanContext().getSpanId());
        info(classObj, JsonUtils.mapToJson(message));
    }

但没有生成跨度。withSpan可以使用哪种方法有限制吗？

上述系统输出的输出是

Trace id 00000000000000000000000000000000
span id 0000000000000000

摇篮配置

implementation('io.opentelemetry:opentelemetry-api:1.6.0')
    implementation('io.opentelemetry:opentelemetry-sdk:1.6.0')

    //pull in the autoconfigure extension so we parse the `otel.resource.attributes` system property used in the example.
    implementation('io.opentelemetry:opentelemetry-sdk-extension-autoconfigure:1.7.0-alpha')
    implementation('io.opentelemetry:opentelemetry-extension-annotations:1.7.0')
    implementation("io.opentelemetry:opentelemetry-api-metrics:1.7.0-alpha")
    implementation('io.opentelemetry:opentelemetry-sdk-metrics:1.7.0-alpha')
    implementation("io.opentelemetry:opentelemetry-exporter-otlp-metrics:1.7.0-alpha")

编辑：如果不是@WithSpan我获得跟踪器并开始/结束跨度，那么跨度确实会在收集器中结束

根据 java doc@WithSpan仅适用于使用代理的 java 应用程序的自动检测。

https://javadoc.io/static/io.opentelemetry/opentelemetry-contrib-auto-annotations/0.5.0/io/opentelemetry/contrib/auto/annotations/WithSpan.html

您要做的是手动检测应用程序。如果你想@WithSpan使用OpenTelemetry java 代理
