Using the AWS SDK for Java

By: Emiley J in Java Tutorials on 2023年05月03日 [フレーム]

The AWS SDK for Java is a collection of APIs provided by Amazon Web Services for Java developers to build Java applications that interact with AWS services such as Amazon S3, EC2, DynamoDB, and others.

To use the AWS SDK for Java, follow these steps:

Download and install the Java Development Kit (JDK) version 7 or higher.
Download the AWS SDK for Java from the AWS website or use a package manager like Maven or Gradle to include it in your project.
Import the AWS SDK for Java into your Java project by adding the necessary dependencies.
Set up the AWS SDK for Java by providing your AWS access key and secret key, which can be obtained from the AWS Management Console.
Use the SDK to interact with AWS services in your Java application.

Here's a sample Java code that uses the AWS SDK for Java to upload a file to Amazon S3:

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.PutObjectRequest;
public class S3Uploader {
 public static void main(String[] args) {
 String accessKey = "your-access-key";
 String secretKey = "your-secret-key";
 String region = "us-west-2";
 String bucketName = "your-bucket-name";
 String objectKey = "your-object-key";
 String filePath = "/path/to/your/file";
 BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
 AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
 .withCredentials(new AWSStaticCredentialsProvider(credentials))
 .withRegion(region)
 .build();
 PutObjectRequest request = new PutObjectRequest(bucketName, objectKey, new File(filePath));
 s3Client.putObject(request);
 System.out.println("File uploaded successfully");
 }
}

This code uses the AWS SDK for Java to create an AmazonS3 client, set up the necessary credentials and region, and upload a file to an S3 bucket.
