Swift Tutorial

Welcome to the OpenStack Java SDK tutorial.

Here you can find a step by step to start working on Swift.

Enjoy!

Setting up Eclipse Project

1. File > New > Other > Maven Project
2. Check on “Create a simple project (skip archetype selection)”
3. Set the following properties

Group Id	Artifact Id	Version
org.openstack	openstack-swift-demo	0.0.1-SNAPSHOT

Configure Maven

Edit your pom.xml (it should look similar to the one below)

<?xml version="1.0"?>

  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

Write the HelloWorld class

package org.openstack.demos.swift;

import java.io.File;
import java.util.HashMap;
import java.util.List;
import java.util.Properties;

import org.openstack.api.storage.AccountResource;
import org.openstack.client.OpenStackClient;
import org.openstack.model.storage.swift.SwiftStorageObject;
import org.openstack.model.storage.swift.SwiftStorageObjectProperties;

public class TestingSwift {

  public static void main(String[] args) {

    	Properties properties = System.getProperties();
	properties.put("verbose", "true");
	properties.put("auth.credentials", "passwordCredentials");
	properties.put("auth.username", "demo");
	properties.put("auth.password", "secret0");
	properties.put("auth.tenantName", "demo");
	properties.put("identity.endpoint.publicURL","http://192.168.1.43:5000/v2.0");

	OpenStackClient openstack = OpenStackClient.authenticate(properties);

	AccountResource account = openstack.getStorageEndpoint();

	account.container("hellocontainer").put();

	account.container("hellocontainer").object("dir1").put();

	account.container("hellocontainer").object("test1")
		.put(new File("pom.xml"), new SwiftStorageObjectProperties() {{
		  setContentType("application/xml");
		  getCustomProperties().putAll(new HashMap<String, String>() {{
		    put("customkey.1", "customvalue.1");
                  }});
		}});

	List<SwiftStorageObject> objects = account.container("hellocontainer").get();

	for (SwiftStorageObject o : objects) {
		System.out.println(o.getName() + " (" + o.getContentType() + ")");
	}
  }
}

HPCloud using the StorageClient (high level api)

[to try the code below you have to build from source, RC3 not releleased yet]

package org.openstack.demos;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Properties;

import org.openstack.client.OpenStackClient;
import org.openstack.client.StorageClient;

public class TestingSwiftClient {
	
	public static final File TEST_FILE = new File("<your_file_path>");
	
	public static final String TEST_FILE_CONTENT_TYPE = "<your_file_content_type>";
	
	public static final String TEST_CONTAINER = "test-container";
	
	public static final String TEST_DIRECTORY = "test-directory";
	
	public static final String TEST_SUBDIRECTORY = "test-directory/test-subdirectory";
	
	public static final String TEST_OBJECT = "test-object";
	
	public static final String TEST_SUBDIRECTORY_OBJECT = "test-directory/test-subdirectory/test-object2";

	public static void main(String[] args) throws IOException {

		Properties properties = System.getProperties();
		properties.put("verbose", "true");
		properties.setProperty("auth.credentials", "apiAccessKeyCredentials");
		properties.setProperty("auth.accessKey", "<your_hpcloud_access_key>");
		properties.setProperty("auth.secretKey", "<your_hpcloud_secret_key>");
		properties.setProperty("auth.tenantId", "<your_hpcloud_tenant_id>");
		properties.put("identity.endpoint.publicURL","<your_hpclud_identity_endpoint>");

		StorageClient swift = OpenStackClient.authenticate(properties).getStorageClient();
		swift.createContainer(TEST_CONTAINER);
		
			swift.createDirectory(TEST_CONTAINER, TEST_DIRECTORY);
			
				swift.createObject(TEST_CONTAINER, TEST_OBJECT, TEST_FILE,
                                new HashMap<String, String>() {{
					put("Content-Type", TEST_FILE_CONTENT_TYPE);
				}});
				
				swift.getObjectAsString(TEST_CONTAINER, TEST_OBJECT);
				
				swift.createDirectory(TEST_CONTAINER, TEST_SUBDIRECTORY);
				
					swift.createObject(TEST_CONTAINER, TEST_SUBDIRECTORY_OBJECT, TEST_FILE);
					
					swift.getObjectAsString(TEST_CONTAINER, TEST_OBJECT);

					swift.deleteObject(TEST_CONTAINER, TEST_SUBDIRECTORY_OBJECT);
				
				swift.deleteObject(TEST_CONTAINER, TEST_SUBDIRECTORY);
				
				swift.deleteObject(TEST_CONTAINER, TEST_OBJECT);
			
			swift.deleteObject(TEST_CONTAINER, TEST_DIRECTORY);
		
		swift.deleteContainer(TEST_CONTAINER);
		
	}
}
