首先引入snakeyaml-1.16.jar的包.

 

直接上代码:

package com.ming.yaml;import java.util.Map;import org.yaml.snakeyaml.Yaml;public class Test {    public static void main(String[] args) {        //yaml转json        Yaml yaml = new Yaml();         String document = " a: 1\n b:\n c: 3\n d: 4\n";         System.out.println(document);         System.out.println(yaml.dump(yaml.load(document)));                //yaml Map取值        Yaml yaml1 = new Yaml();        String document1 = "hello: 25";         Map map = (Map) yaml.load(document1);         System.out.println("{hello=25}"+ map.toString());        System.out.println(""+new Long(25)+map.get("hello"));     }}

 

运行效果如下:

 

 

先笔记一下，也许有用.
