SoundCloud API Java Client and plugin for the Spring Social Framework ( http://www.springsource.org/spring-social )

Use Cases:

To make calls to the SoundCloud Api on behalf of a user (for example favoriting a track), the SoundCloud user must give their permission to your application.  The authentication dance required (where the user is directed to a permission dialog on SoundCloud and then redirected back to your applicaiton) is handled perfectly by the Spring Social framework.  

To use this functionality, create a Spring Social-enabled webapp and simply register the SoundCloudConnectionFactory with the ConnectionFactoryRegistry, eg:

@Bean
  @Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
	public ConnectionFactoryLocator connectionFactoryLocator() {
		ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
		registry.addConnectionFactory(new SoundCloudConnectionFactory(environment.getProperty("soundCloud.consumerKey"),
				environment.getProperty("soundCloud.consumerSecret")));
				return registry;
	}

Once the user has given permission to your Spring Social webapp to use their SoundCloud account ( seee http://www.springsource.org/spring-social for more details ), an authenticated API client can be obtained from the user's connection:

  	Connection<SoundCloud> soundcloudConnection = connectionRepository.findPrimaryConnection(SoundCloud.class);

    SoundCloud authenticatedSoundCloudApi = soundcloud.getApi();
    
  	Page<Track> tracks = authenticatedSoundCloudApi.tracksOperations().search("monsieur adi dancing with the dj");
    
    Track firstResult = tracks.getNumberOfElements() > 0 ? tracks.getContent().get(0) : null;
    
    if (firstResult != null)
    {
        authenticatedSoundCloudApi.meOperations().favoriteTrack(firstResult.getId());
    }

As mentioned above the Spring Social framework here is managing the authentication dance - behind the scenes Spring Social has obtained a SoundCloud session key which is linked to the user's authorisation.  Outside of a Spring-Social enabled webapp, the authenticated API client could be constructed as follows.

    SoundCloud authenticatedSoundCloudApi = new SoundCloudTemplate("myApiKey","mySessionKey");

To make unauthenticated calls (ie. those which do not require an end user's permission) - for example searching for tracks or viewing a user's favorites, this module can be used standalone outside of a Spring-Social-enabled webapp.

To use the API in this way, simply create a new SoundCloudTemplate instance, passing in your applications API key:

    SoundCloud unauthenticatedSoundCloudApi = new SoundCloudTemplate("myApiKey");

    Page<Track> tracks = unauthenticatedSoundCloudApi.usersOperations().userOperations("mattslip").getFavorites();

Usage:

To use this module, either checkout the project, build and install locally ("mvn install" from the base directory of your checkout) or add the following repository to your project's pom:

<repositories>
     <repository>
        <id>opensourceagility-snapshots</id>
        <url>http://repo.opensourceagility.com/snapshots</url>
    </repository>
</repositories>

Then simply add the following dependency to your project's pom:

      <dependency>
         <groupId>org.springframework.social<groupId>
         <artifactId>spring-social-lastfm</artifactId>
         <version>1.0.1-SNAPSHOT</version>
     </dependency>
