How to init " AWSPricing client " by AWSPricingClientBuilder the latest version sdk? - aws-java-sdk

Question

My task is to get aws procuct pricing data, so I do the things as follows:
set the Environment Variables(AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY)
fill the pom.xml(in Eclipse) with the code:
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-pricing</artifactId>
<version>1.11.513</version>
</dependency>
then I code the test method like the code:
public static void testDescribeServices() {
System.out.println("\n\n 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();
}
run the method testDescribeServices(), the message on the console is like this: (I was disappointed)
begin ....

Answer 1

after trying some setting , I make some progress, and the new method is :
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("\n\n step 0004");
List<Service> serviceList = result.getServices();
System.out.println("\n\n step 0005");
}
However, the result is
Exception in thread "main" com.amazonaws.services.pricing.model.AWSPricingException: User: arn:aws:iam::285906155448:user/dev1 is not authorized to perform: pricing:DescribeServices **(Service: AWSPricing; Status Code: 400; Error Code: AccessDeniedException; Request ID: 13155463-4198-11e9-8f92-f1f731c320f2)**
