fastjson（阿里）方法生成JSON數據：

與Gson類似，創建相應類，再使用JSON.toJSONString（）添加對象

---

要求：生成如下JSON數據

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

---

代碼：

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;}@Overridepublic String toString() {return "Person [name=" + name + "sex = "+sex+", age=" + age + "]";}}
