java 实现将java对象转为yaml文件

首先我们建两个类，以下两个类展示的是一个学生拥有多个手机号码联系人.

先是学生类:

package com.ming.yaml.beans;

import java.util.ArrayList;
import java.util.List;

/**
 * 学生类
 * @author ming
 *
 */
public class Student {

    private int id;

    private String name;

    private int age;

    //一个学生有多个电话号码
    List<Tel> tels=new ArrayList<Tel>();

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public List<Tel> getTels() {
        return tels;
    }

    public void setTels(List<Tel> tels) {
        this.tels = tels;
    }

}

然后是联系人:

package com.ming.yaml.beans;

/**
 * 联系人电话类
 * @author ming
 *
 */
public class Tel {

    private String name;

    private String tel;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getTel() {
        return tel;
    }

    public void setTel(String tel) {
        this.tel = tel;
    }

}

测试代码:

package com.ming.yaml;

import java.io.FileWriter;
import java.util.ArrayList;
import java.util.List;

import org.yaml.snakeyaml.Yaml;

import com.ming.yaml.beans.Student;
import com.ming.yaml.beans.Tel;

/**
 *
 * @author ming
 *
 */
public class Test1 {

    public static void main(String[] args) throws Exception{
        Student stu=new Student();
        stu.setName("路飞");
        stu.setAge(24);
        stu.setId(1);
        Tel t=new Tel();
        t.setName("张三");
        t.setTel("10123041445");
        Tel t1=new Tel();
        t1.setName("李四");
        t1.setTel("19923041455");
        List<Tel> tels=new ArrayList<Tel>();
        tels.add(t);
        tels.add(t1);
        stu.setTels(tels);
        Yaml yaml = new Yaml();
        yaml.dump(stu, new FileWriter("stu.yaml"));

    }
}

最后产生的stu.yaml文件的代码如下:

!!com.ming.yaml.beans.Student
age: 24
id: 1
name: 路飞
tels:
- {name: 张三, tel: '10123041445'}
- {name: 李四, tel: '19923041455'}
