sparckjava初识

sparckjava依赖的jar包极少，使用简单，配置route，指定http方法，指定路径即可建立http服务。

一般可用来做简单web程序或restapi服务,引入(maven)和使用简单(直接使用静态类即可)。

官网是：http://sparkjava.com/

简单程序例子：

pom.xml添加dependency

<dependency>
   <groupId>com.sparkjava</groupId>
   <artifactId>spark-core</artifactId>
   <version>2.2</version>
</dependency>

代码：

package com.mongodb;

import spark.Request;
import spark.Response;
import spark.Route;
import spark.Spark;

public class HelloWorldSparkStyle {

	public static void main(String[] args){
		Spark.get("/",new Route() {
			
			@Override
			public Object handle(Request arg0, Response arg1) throws Exception {
				return "hello world from sparkjava.";
			}
		});
	}
}

可以看到eclipse控制台输出
