We Keep Coding

Can we use the same instance of AWS S3 TransferManager or should we create a new instance for each file upload?

I am using a Spring Boot app to expose an API tasked with uploading file to AWS S3.
I am using a single instance of S3 client in the application:
#Bean
public AmazonS3 s3Client() {
BasicAWSCredentials credentials = new BasicAWSCredentials(awsAccessKey, awsSecretAccessKey);
AmazonS3ClientBuilder amazonS3ClientBuilder = AmazonS3ClientBuilder
.standard()
.withCredentials(new AWSStaticCredentialsProvider(credentials))
.withEndpointConfiguration(
new AwsClientBuilder.EndpointConfiguration(
endpointUrl, Regions.EU_WEST_1.getName()));
return amazonS3ClientBuilder.build();
}
Can I create a bean for TransferManager in a similar fashion and reuse the same instance across requests or do I need to create a fresh instance for every API call to upload a file?
What is the recommended practice here?

The recommended practice is to move away from AWS SDK for Java V1. Amazon recommends that you use AWS SDK for Java V2. Now to upload content to an Amazon S3 bucket, you can use the S3TransferManager.
If you are not familiar with using the V2 SDK, I recommend that you read the Developer Guide.
Here is a code example of how to use this to upload an object. And you can use the same instance to upload different objects. All you need to do is to set to pass the correct the values to transferManager.uploadFile().
package com.example.transfermanager;
import software.amazon.awssdk.auth.credentials.EnvironmentVariableCredentialsProvider;
import software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.transfer.s3.FileUpload;
import software.amazon.awssdk.transfer.s3.S3TransferManager;
import java.nio.file.Paths;

*/
public class UploadObject {
public static void main(String[] args) {
final String usage = "\n" +
"Usage:\n" +
" <bucketName> <objectKey> <objectPath> \n\n" +
"Where:\n" +
" bucketName - The Amazon S3 bucket to upload an object into.\n" +
" objectKey - The object to upload (for example, book.pdf).\n" +
" objectPath - The path where the file is located (for example, C:/AWS/book2.pdf). \n\n" ;
if (args.length != 3) {
System.out.println(usage);
System.exit(1);
}
long mb = 1024;
String bucketName = args[0];
String objectKey = args[1];
String objectPath = args[2];
System.out.println("Putting an object into bucket "+bucketName +" using the S3TransferManager");
ProfileCredentialsProvider credentialsProvider = ProfileCredentialsProvider.create();
Region region = Region.US_EAST_1;
S3TransferManager transferManager = S3TransferManager.builder()
.s3ClientConfiguration(cfg ->cfg.region(region)
.credentialsProvider(credentialsProvider)
.targetThroughputInGbps(20.0)
.minimumPartSizeInBytes(10 * mb))
.build();
uploadObjectTM(transferManager, bucketName, objectKey, objectPath);
System.out.println("Object was successfully uploaded using the Transfer Manager.");
transferManager.close();
}
public static void uploadObjectTM( S3TransferManager transferManager, String bucketName, String objectKey, String objectPath) {
FileUpload upload =
transferManager.uploadFile(u -> u.source(Paths.get(objectPath))
.putObjectRequest(p -> p.bucket(bucketName).key(objectKey)));
upload.completionFuture().join();
}
}
UPDATE
As the above API still appears to be in Preview Mode (judging from Maven repo):
https://mvnrepository.com/artifact/software.amazon.awssdk/s3-transfer-manager
You can use the Amazon S3 V2 Service Client to upload objects. V2 is still better practice then V1.
You can use this code:
package com.example.s3;
// snippet-start:[s3.java2.s3_object_upload.import]

looking for a sample code to read parameter value from aws parameter store

looking for a sample java code to read parameter store values like RDS connection string from aws parameter store. appreicate code or any reference links. thanks.

Here is the V2 (not V1) example to read a specific parameter value from the AWS parameter store:
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ssm.SsmClient;
import software.amazon.awssdk.services.ssm.model.GetParameterRequest;
import software.amazon.awssdk.services.ssm.model.GetParameterResponse;
import software.amazon.awssdk.services.ssm.model.SsmException;
public class GetParameter {
public static void main(String[] args) {
final String USAGE = "\n" +
"Usage:\n" +
" GetParameter <paraName>\n\n" +
"Where:\n" +
" paraName - the name of the parameter\n";
if (args.length < 1) {
System.out.println(USAGE);
System.exit(1);
}
// Get args
String paraName = args[0];
Region region = Region.US_EAST_1;
SsmClient ssmClient = SsmClient.builder()
.region(region)
.build();
try {
GetParameterRequest parameterRequest = GetParameterRequest.builder()
.name(paraName)
.build();
GetParameterResponse parameterResponse = ssmClient.getParameter(parameterRequest);
System.out.println("The parameter value is "+parameterResponse.parameter().value());
} catch (SsmException e) {
System.err.println(e.getMessage());
System.exit(1);
}
}
}

import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagement;
import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagementClientBuilder;
import com.amazonaws.services.simplesystemsmanagement.model.GetParametersRequest;
import com.amazonaws.services.simplesystemsmanagement.model.GetParametersResult;
...
private static AWSSimpleSystemsManagement ssmclient = AWSSimpleSystemsManagementClientBuilder

...
GetParametersRequest paramRequest = new GetParametersRequest()
.withNames(parameterName).withWithDecryption(encrypted);
GetParametersResult paramResult = new GetParametersResult();
paramResult = ssmclient.getParameters(paramRequest);

I think GitHub may be of help. I searched for SsmClient getParameter language:java and some of the results seem promising.
This one for example:
public static String getDiscordToken(SsmClient ssmClient) {
GetParameterRequest request = GetParameterRequest.builder().
name("/discord/token").
withDecryption(Boolean.TRUE).
build();
GetParameterResponse response = ssmClient.getParameter(request);
return response.parameter().value();
}

Is there any way to get the file content which is triggring azure blob trigger?

So I have created a Azure blob trigger, and it is working fine as soon as I put some file or create some directory on the blob the trigger happens.
Question: Now I can not figure out how can I get the same file content which causes the blob trigger.
I can get the files using Azure storage library, but I am going to upload lots of files on the blob and want to do some processing on the file which has just written on the blob.
Thanks in advance

It looks pretty straightforward from the example documentation - https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob#trigger---java-example
#FunctionName("blobprocessor")
public void run(
#BlobTrigger(name = "file",
dataType = "binary",
path = "myblob/{name}",
connection = "MyStorageAccountAppSetting") byte[] content,
#BindingName("name") String filename,
final ExecutionContext context
) {
context.getLogger().info("Name: " + filename + " Size: " + content.length + " bytes");
}
The content gets passed in as a byte array.

One of the way we can get the file content is
#FunctionName("BlobTrigger-Java")
public void blobTriggerWhenUploadFile(
#BlobTrigger(name = "content", path = "data/{name}", dataType = "binary", connection = "StorageConnection") String content,
#BindingName("name") String name,
final ExecutionContext context
) {
This is working code
import com.microsoft.azure.functions.annotation.*;
import com.microsoft.azure.functions.*;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
import org.apache.commons.io.IOUtils;
/**
* Azure Functions with Azure Blob trigger.
*/
public class BlobTriggerFunction {
/**
* This function will be invoked when a new or updated blob is detected at the specified path. The blob contents are provided as input to this function.
*
* #return
*/
#FunctionName("BlobTrigger-Java")
public void blobTriggerWhenUploadFile(
#BlobTrigger(name = "content", path = "data/{name}", dataType = "binary", connection = "StorageConnection") byte[] content,
#BindingName("name") String name,
final ExecutionContext context
) {
context.getLogger().info("Java Blob trigger function processed a blob. Name: " + name + "\n Size: " + content.length + " Bytes");
//String result=new String(content,StandardCharsets.UTF_8);
InputStream inputStream = new ByteArrayInputStream(content);
String result = null;
try {
result = IOUtils.toString(inputStream, StandardCharsets.UTF_8);
} catch (IOException e) {
throw new RuntimeException(e);
}
context.getLogger().info("The upload file content is: " + result);
}
}

AmazonS3Client(credentials) is deprecated

I'm trying to read the files available on Amazon S3, as the question explains the problem. I couldn't find an alternative call for the deprecated constructor.
Here's the code:
private String AccessKeyID = "xxxxxxxxxxxxxxxxxxxx";
private String SecretAccessKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
private static String bucketName = "documentcontainer";
private static String keyName = "test";
//private static String uploadFileName = "/PATH TO FILE WHICH WANT TO UPLOAD/abc.txt";
AWSCredentials credentials = new BasicAWSCredentials(AccessKeyID, SecretAccessKey);
void downloadfile() throws IOException
{
// Problem lies here - AmazonS3Client is deprecated
AmazonS3 s3client = new AmazonS3Client(credentials);
try {
System.out.println("Downloading an object...");
S3Object s3object = s3client.getObject(new GetObjectRequest(
bucketName, keyName));
System.out.println("Content-Type: " +
s3object.getObjectMetadata().getContentType());
InputStream input = s3object.getObjectContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
while (true) {
String line = reader.readLine();
if (line == null) break;
System.out.println(" " + line);
}
System.out.println();
} catch (AmazonServiceException ase) {
//do something
} catch (AmazonClientException ace) {
// do something
}
}
Any help? If more explanation is needed please mention it.
I have checked on the sample code provided in .zip file of SDK, and it's the same.

You can either use AmazonS3ClientBuilder or
AwsClientBuilder as alternatives.
For S3, simplest would be with AmazonS3ClientBuilder.
BasicAWSCredentials creds = new BasicAWSCredentials("access_key", "secret_key");
AmazonS3 s3Client = AmazonS3ClientBuilder
.standard()
.withCredentials(new AWSStaticCredentialsProvider(creds))
.build();

Use the code listed below to create an S3 client without credentials:
AmazonS3 s3Client = AmazonS3ClientBuilder.standard().build();
An usage example would be a lambda function calling S3.

You need to pass the region information through the
com.amazonaws.regions.Region object.
Use AmazonS3Client(credentials, Region.getRegion(Regions.REPLACE_WITH_YOUR_REGION))

You can create S3 default client as follows(with aws-java-sdk-s3-1.11.232):
AmazonS3ClientBuilder.defaultClient();

Deprecated with only creentials in constructor, you can use something like this:
val awsConfiguration = AWSConfiguration(context)
val awsCreds = CognitoCachingCredentialsProvider(context, awsConfiguration)
val s3Client = AmazonS3Client(awsCreds, Region.getRegion(Regions.EU_CENTRAL_1))

Using the AWS SDK for Java 2.x, one can also build its own credentialProvider like so:
// Credential provider
package com.myproxylib.aws;
import software.amazon.awssdk.auth.credentials.AwsCredentials;
import software.amazon.awssdk.auth.credentials.AwsCredentialsProvider;
public class CustomCredentialsProvider implements AwsCredentialsProvider {
private final String accessKeyId;
private final String secretAccessKey;
public CustomCredentialsProvider(String accessKeyId, String secretAccessKey) {
this.secretAccessKey = secretAccessKey;
this.accessKeyId = accessKeyId;
}
#Override
public AwsCredentials resolveCredentials() {
return new CustomAwsCredentialsResolver(accessKeyId, secretAccessKey);
}
}
// Crenditals resolver
package com.myproxylib.aws;
import software.amazon.awssdk.auth.credentials.AwsCredentials;
public class CustomAwsCredentialsResolver implements AwsCredentials {
private final String accessKeyId;
private final String secretAccessKey;
CustomAwsCredentialsResolver(String accessKeyId, String secretAccessKey) {
this.secretAccessKey = secretAccessKey;
this.accessKeyId = accessKeyId;
}
#Override
public String accessKeyId() {
return accessKeyId;
}
#Override
public String secretAccessKey() {
return secretAccessKey;
}
}
// Usage of the provider
package com.myproxylib.aws.s3;
public class S3Storage implements IS3StorageCapable {
private final S3Client s3Client;
public S3Storage(String accessKeyId, String secretAccessKey, String region) {
this.s3Client = S3Client.builder().credentialsProvider(new CustomCredentialsProvider(accessKeyId, secretAccessKey)).region(of(region)).build();
}
NOTE:
of course, the library user can get the credentials from wherever he wants, parse it into a java Properties before calling the S3 constructor.
When possible, favour the other methods mentionned in other answers and doc. My use case was necessary for this.

implementation 'com.amazonaws:aws-android-sdk-s3:2.16.12'
val key = "XXX"
val secret = "XXX"
val credentials = BasicAWSCredentials(key, secret)
val s3 = AmazonS3Client(
credentials, com.amazonaws.regions.Region.getRegion(
Regions.US_EAST_2
)
)
val expires = Date(Date().time + 1000 * 60 * 60)
val keyFile = "13/thumbnail_800x600_13_photo.jpeg"
val generatePresignedUrlRequest = GeneratePresignedUrlRequest(
"bucket_name",
keyFile
)
generatePresignedUrlRequest.expiration = expires
val url: URL = s3.generatePresignedUrl(generatePresignedUrlRequest)
GlideApp.with(this)
.load(url.toString())
.apply(RequestOptions.centerCropTransform())
.into(image)

I verified following code below which is working through fiddler proxy. Thanks to how to Capture https with fiddler, in java post which gave me hints:
System.setProperty("http.proxyHost", "127.0.0.1");
System.setProperty("https.proxyHost", "127.0.0.1");
System.setProperty("http.proxyPort", "8888");
System.setProperty("https.proxyPort", "8888");
System.setProperty("javax.net.ssl.trustStore", "C:\\Program Files\\Java\\jdk1.8.0_102\\bin\\FiddlerKeyStore");
System.setProperty("javax.net.ssl.trustStorePassword", "mypassword");

For others who face issue like me we can connect to azure mediaservices using network proxy by using below code
// Set up the MediaContract object to call into the Media Services account
Configuration configuration = MediaConfiguration.configureWithOAuthAuthentication(
mediaServiceUri, oAuthUri, clientId, clientSecret, scope);
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_HOST, "Hostvalue");
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_PORT, "Portvalue");
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_SCHEME, "http");
MediaContract mediaService = MediaService.create(configuration);
Now use the mediaService to perform other operations.
