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());
        }
    }
