如何利用Java函数创建物联网传感器平台？

gcloud functions init my-sensor-platform --runtime java11

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-iot</artifactId>
  <version>1.160.2</version>
</dependency>

import com.google.cloud.functions.BackgroundFunction;
import com.google.cloud.functions.Context;
import com.google.common.io.BaseEncoding;
import com.google.gson.Gson;
import com.google.gson.JsonElement;
import functions.eventpojos.CloudEvent;
import functions.eventpojos.IotCoreEventData;
import java.nio.charset.StandardCharsets;

public class SensorEventHandler implements BackgroundFunction<CloudEvent> {

  private static final Gson gson = new Gson();

  @Override
  public void accept(CloudEvent event, Context context) {
    IotCoreEventData eventData = gson.fromJson(event.getData().toString(), IotCoreEventData.class);

    String payload = new String(
        BaseEncoding.base64().decode(eventData.getBinaryData().getBytes(StandardCharsets.UTF_8)),
        StandardCharsets.UTF_8);
    System.out.println("Received payload: " + payload);
  }
}

gcloud functions deploy SensorEventHandler
