Try code below to get a SAS token with read permission for a blob :

import com.azure.storage.blob.sas.BlobServiceSasSignatureValues;
import com.azure.storage.blob.sas.BlobSasPermission;
import com.azure.storage.blob.BlobClient;
import com.azure.storage.blob.BlobServiceClient;
import com.azure.storage.blob.BlobServiceClientBuilder;
import java.time.OffsetDateTime;

public class App {
        public static void main(String[] args) {

                String connString = "<storage account connection string>";
                String containerName = "<container name>";
                String blobName = "<blob name>";

                BlobServiceClient client = new BlobServiceClientBuilder().connectionString(connString).buildClient();
                BlobClient blobClient = client.getBlobContainerClient(containerName).getBlobClient(blobName);

                BlobSasPermission blobSasPermission = new BlobSasPermission().setReadPermission(true); // grant read
                                                                                                       // permission
                                                                                                       // onmy
                OffsetDateTime expiryTime = OffsetDateTime.now().plusDays(2); // after 2 days expire
                BlobServiceSasSignatureValues values = new BlobServiceSasSignatureValues(expiryTime, blobSasPermission)
                                .setStartTime(OffsetDateTime.now());

                System.out.println(blobClient.getBlobUrl() + "?" + blobClient.generateSas(values));

        }
}

maven dependency:

<dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-storage-blob</artifactId>
  <version>12.9.0</version>
</dependency>
