Spark - A micro framework for creating web applications in Kotlin and Java 8 with minimal effort

Quick start

Java

import static spark.Spark.*;

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

Kotlin

import spark.kotlin.*

fun main(args: Array) {
    val http: Http = ignite()

    http.get("/hello") {
        "Hello Spark Kotlin!"
    }
}

Run and view

http://localhost:4567/hello

（注意：这个Spark和 Apache Spark不一样；这个Spark是一个框架，Apache Spark是一个大数据的分析计算引擎）
