Play Framework • Makes it easy to build web applications with Java and Scala. • Is based on a lightweight, stateless, web-friendly architecture. • Built on Akka, provides predictable and minimal resources consumption (CPU, memory, threads) for • highly-scalable applications.

Servidor: 1 CPU 2 GB Ram

Play Framework • • Develop using Java or Scala Is reactive Use the architecture MVC Uses Netty as App Server, AKKA Http since 2. 6. x (Fewer configurations) • Simulates the behavior of JRebel (more code, less deploys)

Web Services • Hyper. Text Transfer Protocol (HTTP) • Allows communication between a client and a server • Provide a standard means of interoperating between different software apps • Characterized for interoperability and extensibility • Based on XML

SOAP • Simple Object Access Protocol • XML-based • Use WSDL as specification description (Web Services Description Language) • Need to follow a communication protocol

Restful • Software Architecture based on HTTP method (Get, Post, Put, Delete, etc) • Typically use JSON, but can use XML, Text

JSON • • • Java. Script Object Notation Is a lightweight data-interchange format Self-describing Human-reading Is a Protocol

JSON Example

JSON Scheme

Package controllers; import play. libs. Json; import play. mvc. Controller; import play. mvc. Result; public class Home. Controller extends Controller { public Result index(){ Json. Node json = request(). body(). as. Json(); Post. Request request = Json. from. Json(json, Post. Request. class); return ok(Json. to. Json(request)); } }
