Introduction

Play Framework is a free and open-source web application framework that adheres to the model-view-controller (MVC) architectural paradigm. It is developed in Scala and may be accessed from other programming languages that have been converted to JVM bytecode, such as Java. It seeks to improve developer efficiency by utilizing convention over configuration, hot code reloading, and error display in the browser.

Scala programming language support has been provided from the framework's version 1.1. The framework core was rebuilt in Scala in version 2.0. SBT was used for build and deployment, and templates now use Scala rather than Apache Groovy. 

In this article, we will explain the Embedding Play Framework, So before we start with Embedding Play, sit tight and concentrate completely here.

About 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.

Play, being a full-stack framework, offers all of the components required to construct Web Applications and REST services, such as an integrated HTTP server, form handlingCSRF protectiona robust routing system, I18n support, and more. 

Play saves valuable development time by directly supporting common actions and allowing you to see the effects of your effort right away.

 

Embedding Play Framework

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.*;
You can also try this code with Online Java Compiler
Run Code

 

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

construct a server
Server server =
    Server.forRouter(
        (components) ->
            RoutingDsl.fromComponents(components)
                .GET("/hello/:to")
                .routingTo((request, to) -> ok("Hello " + to))
                .build());
You can also try this code with Online Java Compiler
Run Code

 

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

he httpPort method may be used to check the port
CompletionStage<WSResponse> response =
    ws.url("http://localhost:" + server.httpPort() + "/hello/world").get();
You can also try this code with Online Java Compiler
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());
You can also try this code with Online Java Compiler
Run Code

 

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

server.stop();
You can also try this code with Online Java Compiler
Run Code

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.
