利用fastjson将map数据封装到对象中

闲来无事,偶然想到fastjson封装对象的事情,于是便做了一个测试,看来以后可以少些几个工具类了

实体:

package com.site.utils;import java.util.List;/** * Create by szw on 2017/11/24 10:17 */public class Life {    private String name;//姓名    private int age;//年龄    private String country;//国家    private List<String> friend;    public Life() {    }    @Override    public String toString() {        return "Life{" +                "name='" + name + '\'' +                ", age=" + age +                ", country='" + country + '\'' +                ", friend=" + friend +                '}';    }    public String getName() {        return name;    }    public Life(String name, int age, String country, List<String> friend) {        this.name = name;        this.age = age;        this.country = country;        this.friend = friend;    }    public void setName(String name) {        this.name = name;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    public String getCountry() {        return country;    }    public void setCountry(String country) {        this.country = country;    }    public List<String> getFriend() {        return friend;    }    public void setFriend(List<String> friend) {        this.friend = friend;    }}

测试:

package com.site.utils;import ch.qos.logback.core.net.SyslogOutputStream;import com.alibaba.fastjson.JSON;import com.alibaba.fastjson.JSONObject;import java.util.ArrayList;import java.util.HashMap;import java.util.Map;/** * Create by szw on 2017/11/24 11:16 */public class ParseBean {    public static void main(String[] args) {        Map<String, Object> hashMap = new HashMap<>();        hashMap.put("name", "诸葛亮");        hashMap.put("age", 27);        hashMap.put("country", "蜀");        hashMap.put("friend", new ArrayList<>());        String s = JSON.toJSONString(hashMap);        System.out.println(s);        Life life = JSON.parseObject(s, Life.class);        System.out.println(life.toString());    }}
