alibaba Json 与对象之间的互相转换

本文主要记录如何实现 alibaba Json 与对象之间的互转操作，使用了 fastjson-1.2.39.jar 包实现：

1、pom 文件：

<!--fastjson-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.39</version>
</dependency>

2、实体类：

import lombok.Data;

import java.util.Date;

@Data
public class Staff {

    private String personName;
    private String person_id;
    private String personnation;
    private Integer AGE;
    private String sex;
    private Integer telPhone;
    private Date birthday;
}

3、启动类：

import com.alibaba.fastjson.JSON;

public class ceshi {

    /**
     * json字符串 与 对象的互相转化
     */
    @Test
    public void jsonToBeanObject(){

        // bean : personName, person_id, personnation, AGE, sex, telPhone, birthday(Date)
        // json : personname, person_id, personNation, aGe, SEX, telPhone, birthday

        // json字符串转化为对象
        String jsonString = "{personname:'Antony','person_id':'371xxxxxxxxxxx','personNation':'汉族','aGe':'13','SEX':'male','telPhone':'88888','birthday': '2020-02-14 00:00:00'}";
        Staff staff = JSON.parseObject(jsonString, Staff.class);
        log.info(staff.toString());

        // 对象转化为json字符串
        String jsonStr = JSON.toJSONString(staff);
        log.info(jsonStr);
        
        // 对象转化为jsonObject
        (JSONObject)JSON.toJSON(staff);
    }

}

结果：
