Dur­ing yesterday’s per­sonal Hackathon, I started a project which I might intro­duce here some­time.  But the coolest rev­e­la­tion was (again) how easy it was to get up and running.

1. Cre­ate a new Play Project
2. Add Secure Social and con­fig­ure it for Twit­ter, and use the InMem­o­ryUserSer­vice from the exam­ples.  (all this is described here http://​secure​so​cial​.ws/​g​u​i​d​e​/​g​e​t​t​i​n​g​-​s​t​a​r​t​e​d​.​h​tml and only takes a minute)
3. Add the depen­decy to twitter4j to your Build.scala like this:
   "org.twitter4j"% "twitter4j-core"% "3.0.3"
4. Secure your con­troller action method to force the (Login) Authen­ti­ca­tion with Twit­ter.  Remem­ber — because you are using the InMem­o­ryUserSer­vice none of the Authen­ti­ca­tion data is stored — you will have to recon­nect each time.
   @SecureSocial.SecuredAction
5. I then added these stan­dard meth­ods to get the Authen­ti­cated Twit­ter User, Token, Secret and the twitter4J Con­nec­tion: (The tokenSe­cret, token and cur­rent User are com­ing from the Secure Social Oauth1 Con­nec­tion, and are used to authen­ti­cate the Twit­ter Con­nec­tion.
   public static Twitter getTwitterInstance() {
// The factory instance is re-useable and thread safe.
TwitterFactory factory = new TwitterFactory();
Twitter twitter = new TwitterFactory().getInstance();twitter.setOAuthConsumer(Play.application().configuration().getString("securesocial.twitter.consumerKey"), Play.application().configuration().getString("securesocial.twitter.consumerSecret"));
twitter4j.auth.AccessToken accessToken = new twitter4j.auth.AccessToken(token(), tokenSecret());
twitter.setOAuthAccessToken(accessToken);
return twitter;
}
public static String tokenSecret() {
String retval = "";
scala.collection.Iterator iterator = Application.getCurrentUser().oAuth1Info().iterator();
while (iterator.hasNext()) {
OAuth1Info oAuth1Info = iterator.next();
retval = oAuth1Info.secret();
}
return retval;
}
public static String token() {
String retval = "";
scala.collection.Iterator iterator = Application.getCurrentUser().oAuth1Info().iterator();
while (iterator.hasNext()) {
OAuth1Info oAuth1Info = iterator.next();
retval = oAuth1Info.token();
}
return retval;
}
public static Identity getCurrentUser() {
return (Identity) ctx().args.get(SecureSocial.USER_KEY);
}

6. Then I added some code in my Con­troller to list (for exam­ple) my Fol­low­ers
   
long cursor = -1;
IDs ids;
System.out.println("Listing following ids.");
do {
ids = twitter.getFriendsIDs(cursor);
for (long id : ids.getIDs()) {
twitter4j.User twitterUser = twitter.showUser(id);
twitterUsers.put(twitterUser.getScreenName(), new TwitterUser(id,twitterUser));
System.out.println(id);
}
} while ((cursor = ids.getNextCursor()) != 0);


Yes, that is it…
