1	# AWS SDK for Java 2.x - Amazon S3
2
3	## Overview
4
5	Provides patterns for S3 operations: bucket management, object upload/download with multipart support, presigned URLs, S3 Transfer Manager, and S3-specific configurations using AWS SDK for Java 2.x.
6
7	## When to Use
8
9	- Creating, listing, or deleting S3 buckets with proper configuration
10	- Uploading or downloading objects from S3 with metadata and encryption
11	- Working with multipart uploads for large files (>100MB) with error handling
12	- Generating presigned URLs for temporary access to S3 objects
13	- Copying or moving objects between S3 buckets with metadata preservation
14	- Setting object metadata, storage classes, and access controls
15	- Implementing S3 Transfer Manager for optimized file transfers
16	- Integrating S3 with Spring Boot applications for cloud storage
17
18	## Quick Reference
19
20	\| Operation \| Method \| Notes \|
21	\|-----------\|--------\|-------\|
22	\| Create bucket \| `createBucket()` \| Wait with `waiter().waitUntilBucketExists()` \|
23	\| Upload object \| `putObject()` \| Use `RequestBody.fromFile()` \|
24	\| Download object \| `getObject()` \| Streams to file or memory \|
25	\| Delete objects \| `deleteObjects()` \| Batch up to 1000 keys \|
26	\| Presigned URL \| `presigner.presignGetObject()` \| Max 7 days expiration \|
27
28	### Storage Classes
29
30	\| Class \| Use Case \|
31	\|-------\|----------\|
32	\| `STANDARD` \| Frequently accessed data \|
33	\| `STANDARD_IA` \| Infrequently accessed data \|
34	\| `GLACIER` \| Long-term archive \|
35	\| `INTELLIGENT_TIERING` \| Automatic cost optimization \|
36
37	## Instructions
38
39	### 1. Add Dependencies
40
41	```xml
42	<dependency>
43	<groupId>software.amazon.awssdk</groupId>
44	<artifactId>s3</artifactId>
45	<version>2.20.0</version>
46	</dependency>
47
48	<dependency>
49	<groupId>software.amazon.awssdk</groupId>
50	<artifactId>s3-transfer-manager</artifactId>
51	<version>2.20.0</version>
52	</dependency>
53	```
54
55	### 2. Create S3 Client
56
57	```java
58	S3Client s3Client = S3Client.builder()
59	.region(Region.US_EAST_1)
60	.build();
61
62	// With retry logic
63	S3Client s3Client = S3Client.builder()
64	.region(Region.US_EAST_1)
65	.overrideConfiguration(b -> b
66	.retryPolicy(RetryPolicy.builder()
67	.numRetries(3)
68	.build()))
69	.build();
70	```
71
72	### 3. Create Bucket
73
74	```java
75	CreateBucketRequest request = CreateBucketRequest.builder()
76	.bucket(bucketName)
77	.build();
78
79	s3Client.createBucket(request);
80
81	// Wait until ready
82	s3Client.waiter().waitUntilBucketExists(
83	HeadBucketRequest.builder().bucket(bucketName).build()
84	);
85	```
86
87	### 4. Upload Object
88
89	```java
90	PutObjectRequest request = PutObjectRequest.builder()
91	.bucket(bucketName)
92	.key(key)
93	.contentType("application/pdf")
94	.serverSideEncryption(ServerSideEncryption.AES256)
95	.storageClass(StorageClass.STANDARD_IA)
96	.build();
97
98	s3Client.putObject(request, RequestBody.fromFile(Paths.get(filePath)));
99
100	// Validate upload completion
101	HeadObjectResponse headResp = s3Client.headObject(HeadObjectRequest.builder()
102	.bucket(bucketName)
103	.key(key)
104	.build());
105	```
106
107	### 5. Download Object
108
109	```java
110	GetObjectRequest request = GetObjectRequest.builder()
111	.bucket(bucketName)
112	.key(key)
113	.build();
114
115	s3Client.getObject(request, Paths.get(destPath));
116	```
117
118	### 6. Generate Presigned URL
119
120	```java
121	try (S3Presigner presigner = S3Presigner.create()) {
122	GetObjectRequest getRequest = GetObjectRequest.builder()
123	.bucket(bucketName)
124	.key(key)
125	.build();
126
127	GetObjectPresignRequest presignRequest = GetObjectPresignRequest.builder()
128	.signatureDuration(Duration.ofMinutes(10))
129	.getObjectRequest(getRequest)
130	.build();
131
132	String url = presigner.presignGetObject(presignRequest).url().toString();
133	}
134	```
135
136	### 7. Use Transfer Manager (Large Files)
137
138	```java
139	try (S3TransferManager tm = S3TransferManager.create()) {
140	UploadFileRequest request = UploadFileRequest.builder()
141	.putObjectRequest(req -> req.bucket(bucketName).key(key))
142	.source(Paths.get(filePath))
143	.build();
144
145	FileUpload upload = tm.uploadFile(request);
146	CompletedFileUpload result = upload.completionFuture().join();
147	}
148	```
149
150	## Best Practices
151
152	### Performance
153	- Use S3 Transfer Manager: Automatic multipart uploads for files >100MB
154	- Reuse S3 Client: Clients are thread-safe; reuse throughout application
155	- Enable async operations: Use `S3AsyncClient` for I/O-bound operations
156	- Configure timeouts: Set appropriate timeouts for large file operations
157
158	### Security
159	- Use temporary credentials: IAM roles or AWS STS for short-lived tokens
160	- Enable encryption: Use AES-256 or AWS KMS for sensitive data
161	- Use presigned URLs: Avoid exposing credentials with temporary access
