Java developers-Embedding Play

Embedding Play Framework

While Play apps are most typically utilized as their own container, a Play server may also be embedded within your own existing application. This may be used in conjunction with the Twirl template compiler and the Play routes compiler, but they are not required. A popular use case for embedding a Play application is when you simply have a few very simple routes. The Server factory methods are the easiest approach to launching an embedded Play server. 

If all you need to do is offer some simple routes, you may use the Routing DSL, which requires the following imports:

import play.routing.RoutingDsl;
import play.server.Server;
import static play.mvc.Controller.*;

Then, using the forRouter method, you can construct a server:

Server server =
    Server.forRouter(
        (components) ->
            RoutingDsl.fromComponents(components)
                .GET("/hello/:to")
                .routingTo((request, to) -> ok("Hello " + to))
                .build());

By default, this will launch a server in test mode on a random port. The httpPort method may be used to check the port:

CompletionStage<WSResponse> response =
    ws.url("http://localhost:" + server.httpPort() + "/hello/world").get();

Run Code

You may set up the server by specifying a port and/or mode:

Server server =
    Server.forRouter(
        (components) ->
            RoutingDsl.fromComponents(components)
                .GET("/hello/:to")
                .routingTo((request, to) -> ok("Hello " + to))
                .build());

To stop the server after it has been launched, just use the stop method:

server.stop();

Frequently Asked Questions

Is Play a framework or a Library?

Play is a Java and Scala Framework

What Exactly is this Play Framework?

Play is a high-productivity Java and Scala online application framework that connects web application components and APIs. Online developers created Play to aid with the creation of web applications.

Explain what exactly it is, Scala.

Scala is a powerful statically typed overall programming language that can be used for both object-oriented and functional programming. Many of Scala's design decisions are intended to answer concerns leveled against Java.

What tools are available in Embedding Play?

Java class compilers, in particular, are widely accessible from a variety of vendors. They are reasonably priced and may be used on PC, Mac, and UNIX workstations. These class compilers are also employed in the development of commercial applications and Web applets. As a result, the development environments are more advanced than the majority of the tools now used by embedded developers.

Is Java Appropriate for Embedded Play Systems?

Embedded developers often use a different set of evaluation criteria than traditional software developers. Even if Java is the finest language for creating commercial programs and Web  applets, it may not be suitable for use as an embedded language. Deterministic behavior, a compact memory footprint, and efficient execution are among the most significant requirements for embedded languages.
