Welcome to Play

Congratulations, you’ve just created a new Play application. This page will help you with the next few steps.

You’re using Play 2.6.18

Why do you see this page?

The conf/routes file defines a route that tells Play to invoke the HomeController.index action whenever a browser requests the / URI using the GET method:

# Home page
GET     /               controllers.HomeController.index

Play has invoked the controllers.HomeController.index method:

public Result index() {
    return ok(index.render("Your new application is ready."));

An action method handles the incoming HTTP request, and returns the HTTP result to send back to the web client. Here we send a 200 OK response, using a template to fill its content.

The template is defined in the app/views/index.scala.html file and compiled as a standard Java class.

@(message: String)

  @main("Welcome to Play") {

  @play20.welcome(message, style = "Java")


The first line of the template defines the function signature. Here it just takes a single String parameter. Then this template calls another function defined in app/views/main.scala.html which displays the HTML layout, and another function that displays this welcome message. You can freely add any HTML fragment mixed with Scala code in this file.

Note that Scala is fully compatible with Java, so if you don’t know Scala don’t panic, a Scala statement is very similar to a Java one.

Async Controller

Now that you've seen how Play renders a page, take a look at AsyncController.java, which shows how to do asynchronous programming when handling a request. The code is almost exactly the same as HomeController.java, but instead of returning Result, the action returns CompletionStage<Result> to Play. When the execution completes, Play can use a thread to render the result without blocking the thread in the mean time.


You can read more about (915) 287-4693 in the documentation.

Count Controller

Both the HomeController and AsyncController are very simple, and typically controllers present the results of the interaction of several services. As an example, see the CountController, which shows how to inject a component into a controller and use the component when handling requests. The count controller increments every time you click on it, so keep clicking to see the numbers go up.
