使用的代码示 AWS IoT FleetWise 例 AWS SDKs
以下代码示例向您展示了如何 AWS IoT FleetWise 使用 AWS 软件开发套件 (SDK)。
基础知识是向您展示如何在服务中执行基本操作的代码示例。
操作是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。
开始使用
以下代码示例展示了如何开始使用 AWS IoT FleetWise。

public class HelloFleetwise {
public static void main(String[] args) {
ListSignalCatalogs();
}
public static void ListSignalCatalogs() {
try (IoTFleetWiseClient fleetWiseClient = IoTFleetWiseClient.builder()
.region(Region.US_EAST_1)
.credentialsProvider(DefaultCredentialsProvider.create())
.build()) {
ListSignalCatalogsRequest request = ListSignalCatalogsRequest.builder()
.maxResults(10) // Optional: limit per page
.build();
ListSignalCatalogsIterable paginator = fleetWiseClient.listSignalCatalogsPaginator(request);
boolean found = false;
for (ListSignalCatalogsResponse response : paginator) {
for (SignalCatalogSummary summary : response.summaries()) {
found = true;
System.out.println("Catalog Name: " + summary.name());
System.out.println("ARN: " + summary.arn());
System.out.println("Created: " + summary.creationTime());
System.out.println("Last Modified: " + summary.lastModificationTime());
System.out.println("---------------");
}
}
if (!found) {
System.out.println("No AWS Fleetwise Signal Catalogs were found.");
}
} catch (IoTFleetWiseException e) {
System.err.println("Error listing signal catalogs: " + e.awsErrorDetails().errorMessage());
throw new RuntimeException(e);
}
}
