This is a Play 2.3 Java project to demo Acceptto CAS service.
- Install Play 2.3 (Activator)
git clone https://github.com/acceptto-corp/acceptto-sso-java-clientcd acceptto-sso-java-clientactivator run- Open a browser and navigate to localhost:9000
Activator will automatically download all dependencies which may take some time depending on your internet connection.
You can use this sample and change it to meet your needs or you can create your own client from scratch. We use pac4j as CAS client and play-pac4j for Play integration.
Create a new play-java project:
activator new
Add the following dependencies:
libraryDependencies ++= Seq(
"org.pac4j" % "play-pac4j_java" % "1.3.0-SNAPSHOT",
"org.pac4j" % "pac4j-cas" % "1.6.0-SNAPSHOT"
)Add the following resolver:
resolvers ++= Seq(
"Sonatype snapshots repository" at "https://oss.sonatype.org/content/repositories/snapshots/"
)Config CAS client in onStart method of Global settings class.
import org.pac4j.cas.client.CasClient;
import org.pac4j.core.client.Clients;
import org.pac4j.play.Config;
import play.Application;
import play.GlobalSettings;
import play.Play;
public class Global extends GlobalSettings {
@Override
public void onStart(final Application app) {
final String baseUrl = Play.application().configuration().getString("baseUrl");
final String casUrl = Play.application().configuration().getString("casUrl");
// CAS
final CasClient casClient = new CasClient();
casClient.setCasLoginUrl(casUrl);
final Clients clients = new Clients(baseUrl + "/callback", casClient);
Config.setClients(clients);
}
}Authentication controller should inherit from JavaController then you can use:
getRedirectActionto obtain the redirection actiongetUserProfileto obtain user profile if it was available
package controllers;
import play.*;
import play.mvc.*;
import views.html.*;
import org.pac4j.play.java.*;
import org.pac4j.core.profile.CommonProfile;
public class Application extends JavaController {
public static Result index() {
final CommonProfile profile = getUserProfile();
final String url = getRedirectAction("CasClient", "/").getLocation();
return ok(views.html.index.render(profile, url));
}
@RequiresAuthentication(clientName = "CasClient")
public static Result protectedIndex() {
// profile
final CommonProfile profile = getUserProfile();
return ok(views.html.protectedIndex.render(profile));
}
}If the user is not authorized by Acceptto he or she will see the Authenticate with Acceptto CAS button, otherwise he or she will see the authorized profile information.
@(profile : org.pac4j.core.profile.CommonProfile, urlCas: String)
<div>
@profile match {
case _: org.pac4j.cas.profile.CasProfile => {
<p>
<a href="logout">Logout</a>
</p>
@profile
}
case _ => {
<a href="@urlCas">Authenticate with Acceptto CAS</a><br />
}
}
</div>The final step is to set your routes.
GET / controllers.Application.index()
GET /protected/index.html controllers.Application.protectedIndex()
GET /callback org.pac4j.play.CallbackController.callback()
POST /callback org.pac4j.play.CallbackController.callback()
GET /logout org.pac4j.play.CallbackController.logoutAndRedirect()
