java 实现yaml 数据转json与map

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
 b:
 c: 3
 d: 4
"; 
        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.
