Java Code Snippets

You can interact with Azure using the following sample code snippets:

Read VCAP_SERVICES

Sample Code

@Value("${vcap.services.objectstore.credentials.account_name}")  
String accountName; 

@Value("${vcap.services.objectstore.credentials.container_name}")  
String containerName;  

@Value("${vcap.services.objectstore.credentials.container_uri}")  
String containerUri;  

@Value("${vcap.services.objectstore.credentials.sas_token}")  
String sasToken;  

@Value("${vcap.services.objectstore.credentials.region}")   
String region;

Get container reference

Sample Code

CloudBlobContainer cloudBlobContainer = new CloudBlobContainer(new URI(containerUri + "?" + sasToken));

Get BlockBlob reference

Sample Code

String blobName = "test-blob-1";
CloudBlockBlob cloudBlockBlob = new CloudBlockBlob(new URI(containerUri + "/" + blobName + "?" + sasToken));

List blobs in the container

Sample Code

for (ListBlobItem listBlobItem : cloudBlobContainer.listBlobs()) {
	System.out.println("Storage URI: " + listBlobItem.getStorageUri());
}

Upload blob

Sample Code

String blobContent = "This is blob content text.";
InputStream inputStream = new ByteArrayInputStream(blobContent.getBytes("UTF-8"));
cloudBlockBlob.upload(inputStream, blobContent.length());

Download blob

Sample Code

OutputStream outputStream = new ByteArrayOutputStream();
cloudBlockBlob.download(outputStream);

Delete Blob
Sample Code
```
cloudBlockBlob.deleteIfExists();
```

Instead of providing blob content as text, you can provide blobs by providing file path. For more information, see Quickstart: Azure Blob Storage client library for Java SE Information published on non-SAP site .
