fastjson（阿里）方法生成JSON数据：

与Gson类似，创建相应类，再使用JSON.toJSONString（）添加对象

---

要求：生成如下JSON数据

1.{“age”:3,”name”:”zhangsan”,”sex”:true,”weight”:180}

---

代码：

package com.qf.demo7;

import com.alibaba.fastjson.JSON;

/**

 * Gson   toJson

 * FastJson   toJsonString

 * @author Administrator

 *

 */

public class Test {

    public static void main(String[] args) {

        Person1 person = new Person1("zhangsan",true,3,180);

        String json = JSON.toJSONString(person);

        System.out.println(json);

    }

}

class Person1{

    private String name;

    private boolean sex;

    private int age;

    private int weight;

    public Person1(String name,boolean sex, int age,int weight) {

        super();

        this.name = name;

        this.sex = sex;

        this.age = age;

        this.weight = weight;

    }

    public Person1() {

        super();

    }

    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 int getWeight() {

        return weight;

    }

    public void setWeight(int weight) {

        this.weight = weight;

    }

    public boolean isSex() {

        return sex;

    }

    public void setSex(boolean sex) {

        this.sex = sex;

    }

    @Override

    public String toString() {

        return "Person [name=" + name + "sex = "+sex+", age=" + age + "]";

    }

}
