javabean生成json文件 java生成json格式数据的文件

话不多说直接上代码

package ram;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import java.io.*;

public class Main {

    //存放json数据
    public static void main(String[] args) throws IOException {
        //输出路径
        String path = "D:\\WangZY\\data\\data1.json";
        //实例化userall 自己写的一个userall方法 代码在下方
        UserAll userAll = new UserAll();
        //路径
        File file = new File(path);
        //判断路径是否存在，不存在就创建
        if(!file.getParentFile().exists()){
            file.getParentFile().mkdir();
        }
        file.createNewFile();
        //写入的路径 和 编码格式
        Writer writer = new OutputStreamWriter(new FileOutputStream(file),"UTF-8");
        //循环输出XXX条数据随意改（输出10000条json数据）
        for (int i = 1; i <=10000 ; i++) {
            //调用userall中的添加数据方法 User自己写的类 代码在下方
            User user = userAll.getUserAll();
            //（01）  标准json格式 建议用下方的（02）
            //String userData = JSON.toJSONString(user,SerializerFeature.PrettyFormat,SerializerFeature.WriteMapNullValue,           SerializerFeature.WriteDateUseDateFormat);
            //拿到数据 （02）
            String userData = JSON.toJSONString(user);
            //将数据写入
            writer.write(userData+"\n");
            System.out.println(Main.class+"输出了："+"\t"+i+"条数据！！！");
        }
        writer.flush();
        writer.close();
    }
}

user类代码
就是定义几个json需要的元素

package ram;

public class User {

    private String id;//id
    private String name;//姓名
    private int age; // 年龄
    private String sex;//性别
    private String province; //省份
    private String city; //城市
    private String pione;//手机号
    private String profession; //职业
    private String salary; //工资
    private String hobby; //爱好
    private String date;  //访问时间

    public User() {

    }

    public User(String id, String name, int age, String sex, String province, String city, String pione, String profession, String salary, String hobby, String date) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.sex = sex;
        this.province = province;
        this.city = city;
        this.pione = pione;
        this.profession = profession;
        this.salary = salary;
        this.hobby = hobby;
        this.date = date;
    }

    public String getId() {
        return id;
    }

    public void setId(String 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 String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public String getProvince() {
        return province;
    }

    public void setProvince(String province) {
        this.province = province;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getPione() {
        return pione;
    }

    public void setPione(String pione) {
        this.pione = pione;
    }

    public String getProfession() {
        return profession;
    }

    public void setProfession(String profession) {
        this.profession = profession;
    }

    public String getSalary() {
        return salary;
    }

    public void setSalary(String salary) {
        this.salary = salary;
    }

    public String getHobby() {
        return hobby;
    }

    public void setHobby(String hobby) {
        this.hobby = hobby;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }
}

UserAll的代码
这里面的赋值我都是自己写的随机方法（随机姓名，随机id，随机性别··············）

package ram;

import org.apache.commons.lang.RandomStringUtils;

import static ram.RandomTest.*;//自己写的一个随机类 
import static ram.SiteAll.place;//自己洗的一个随机城市方法

public class UserAll {

    //添加信息
    public static User getUserAll(){
        User user = new User();
        //RandomTest 是一个自写的随机的类
        //设置id
             user.setId(RandomStringUtils.random(6,"1234567890"));
        //设置姓名 赋值我全是调用的自己写的随机方法 你们可以直接写值比如 ·· user.setName("自己随意就好")
        user.setName(RandomTest.RandomName());
        //设置年龄
        user.setAge(RandomTest.getUserAge());
        //设置性别
        user.setSex(RandomTest.getUserSex()==1?"男":"女");
        //设置省份
        String[] string = place[getUserRandom(place.length)];
        user.setProvince(string[0]);
        //设置城市
        user.setCity(string[(getUserRandom((string.length)))]);
        //设置手机号
        user.setPione(RandomTest.getUserPhone());
        //设置职业
        String zhiYe = (getUserZhiYe()==1?"打野":getUserZhiYe()==2?
                "法师":getUserZhiYe()==3?"射手":getUserZhiYe()==4?"辅助":"上单");
        user.setProfession(zhiYe);
        //设置工资
        user.setSalary(RandomTest.getUserSalary());
        //设置爱好
        String hobby = (getUserHobby()==1?"打球":getUserHobby()==2?"打游戏":getUserHobby()==3?"看电影":
                getUserHobby()==4?"玩手机":getUserHobby()==5?"吃零食":getUserHobby()==6?"购物":
                        getUserHobby()==7?"看女人":getUserHobby()==8?"睡觉":getUserHobby()==9?"学习":"炸街");
        user.setHobby(hobby);
        //设置时间
        user.setDate(RandomTest.getUserDate());
        return user;
    }

}

自己去写的路径里找输出的文件
给你们看一下结果

感觉好理解的伙伴们 记得给点个赞哦！！！

谢谢观看！！
