Моя задача — получить данные о ценах aws procuct, поэтому я делаю следующее:

1. задайте переменные среды (AWS_ACCESS_KEY_ID и AWS_SECRET_ACCESS_KEY)

2. заполните pom.xml (в Eclipse) с помощью кода:

 <dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-pricing</artifactId>
    <version>1.11.513</version>
</dependency>
  

3. затем я кодирую метод тестирования, подобный коду:

 public static void testDescribeServices() {
    System.out.println("nn begin ....");
    AWSPricing client = AWSPricingClientBuilder.standard().withRegion("us-east-1").build();
    System.out.println("step 0001");
    DescribeServicesRequest servicesRequest = new DescribeServicesRequest();
    servicesRequest.setServiceCode("AmazonEC2");
    DescribeServicesResult result = client.describeServices(servicesRequest);
    List<Service> serviceList = result.getServices();
}
  

4. запустите метод testDescribeServices(), сообщение на консоли выглядит следующим образом: (Я был разочарован)

 begin ....

попробовав некоторые настройки, я добился некоторого прогресса, и новый метод :

 public static void testDescribeServices(String accessKey, String secretKey) {
    BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(accessKey, secretKey);
    AWSCredentialsProvider credentialsProvider = new AWSStaticCredentialsProvider(basicAWSCredentials);
    AWSPricingClientBuilder builder = AWSPricingClientBuilder.standard();
    builder.setCredentials(credentialsProvider);
    builder.withRegion("us-east-1");
    CsmConfigurationProvider csmConfigurationProvider = new EnvironmentVariableCsmConfigurationProvider();
    builder.setClientSideMonitoringConfigurationProvider(csmConfigurationProvider);
    System.out.println("step 0001");
    AWSPricing awsPricing = builder.build();
    System.out.println("step 0002");
    DescribeServicesRequest servicesRequest = new DescribeServicesRequest();
    servicesRequest.setServiceCode("AmazonEC2");
    System.out.println("step 0003");
    DescribeServicesResult result = awsPricing.describeServices(servicesRequest);
    System.out.println("nn step 0004");
    List<Service> serviceList = result.getServices();
    System.out.println("nn step 0005");
}
  

Однако результатом является
