我正在尝试使用azure monitor opentelemetry exporter client library for java将所有跟踪/跨度从spring cloud sleuth导出到azure monitor。这种集成似乎只适用于最新版本的springcloudsleuth，在最近的依赖版本更新之后。
但不是使用 azureMonitorExporter.export(spanData) 手动地，我想通过为azureexporter添加一个配置来自动导出整个应用程序的所有跟踪/跨度。这样就可以很容易地添加到新项目中。
我没有太多使用spring/sleuth/opentelemetry的经验，但是azuremonitorexporter实现了spanexporter，所以我认为一个选项可以是创建一个包含以下内容的配置类。

@Bean
public SpanExporter exporter() {
    return new AzureMonitorExporterBuilder()
        .instrumentationKey("{KEY}")
        .buildExporter();
};

然后可以在主类中使用：

@Autowired
SpanExporter exporter;

但是，我不确定这是否是正确的方法，也不知道如何从这里继续让导出程序开始自动将跟踪/跨度导出到azure monitor。
我的pom.xml如下所示：
