Reference

Definition

Package:: com.azure.storage.blob

Maven Artifact:: com.azure:azure-storage-blob:12.16.0

Overloads

Creates a new block blob. By default this method will not overwrite an existing blob.

Code Samples

try {
     client.uploadFromFile(filePath);
     System.out.println("Upload from file succeeded");
 } catch (UncheckedIOException ex) {
     System.err.printf("Failed to upload from file %s%n", ex.getMessage());
 }

uploadFromFile(String filePath, boolean overwrite)

Creates a new block blob, or updates the content of an existing block blob.

Code Samples

try {
     boolean overwrite = false;
     client.uploadFromFile(filePath, overwrite);
     System.out.println("Upload from file succeeded");
 } catch (UncheckedIOException ex) {
     System.err.printf("Failed to upload from file %s%n", ex.getMessage());
 }

uploadFromFile(String filePath, ParallelTransferOptions parallelTransferOptions, BlobHttpHeaders headers, Map<String,String> metadata, AccessTier tier, BlobRequestConditions requestConditions, Duration timeout)

Creates a new block blob, or updates the content of an existing block blob.

To avoid overwriting, pass "*" to setIfNoneMatch(String ifNoneMatch).

Code Samples

BlobHttpHeaders headers = new BlobHttpHeaders()
     .setContentMd5("data".getBytes(StandardCharsets.UTF_8))
     .setContentLanguage("en-US")
     .setContentType("binary");

 Map<String, String> metadata = Collections.singletonMap("metadata", "value");
 BlobRequestConditions requestConditions = new BlobRequestConditions()
     .setLeaseId(leaseId)
     .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));
 Long blockSize = 100L * 1024L * 1024L; // 100 MB;
 ParallelTransferOptions parallelTransferOptions = new ParallelTransferOptions().setBlockSizeLong(blockSize);

 try {
     client.uploadFromFile(filePath, parallelTransferOptions, headers, metadata,
         AccessTier.HOT, requestConditions, timeout);
     System.out.println("Upload from file succeeded");
 } catch (UncheckedIOException ex) {
     System.err.printf("Failed to upload from file %s%n", ex.getMessage());
 }
