Spark is a free and open-source software web application framework and domain-specific language written in Java. It is an alternative to other Java web application frameworks such as JAX-RS, Play framework and Spring MVC. It runs on an embedded Jetty web server by default, but can be configured to run on other webservers.

Inspired by Sinatra,[citation needed] it does not follow the model–view–controller pattern used in other frameworks, such as Spring MVC. Instead, Spark is intended for "quickly creating web-applications in Java with minimal effort."[1]

Spark was created and open-sourced in 2011 by Per Wendel, and was completely rewritten for version 2 in 2014. The rewrite was hugely centered on the Java 8 lambda philosophy, so Java 7 is officially not supported in version 2 and above.

Example (Hello World)

import static spark.Spark.*;

public class HelloWorld {
   public static void main(String[] args) {
      get("/hello", (request, response) -> "Hello World!");
   }
}
