例子代码：

Student.java

 public class Student {    private int id;    private String name;    private String email;    private String address;    private Birthday birthday;     public String toString() {        return "姓名：" + this.name + " ID: " + this.id + " 地址： " + this.address + " 生日： " + this.birthday + " 邮箱： " + this.email;    }public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public Birthday getBirthday() {return birthday;}public void setBirthday(Birthday birthday) {this.birthday = birthday;}    }

Birthday.java

public class Birthday {public Birthday() {}        public Birthday(String birthday) {        super();        this.birthday = birthday;    }        private String birthday;            @Override    public String toString() {        return this.birthday;    }public String getBirthday() {return birthday;}public void setBirthday(String birthday) {this.birthday = birthday;}}

Test.java

public class JsonlibTest {private static JSONArray jsonArray = null;private static JSONObject jsonObject = null;private static Student stu = null;private Train train = null;public static void main(String args[]){jsonArray = new JSONArray();jsonObject = new JSONObject();stu = new Student();stu.setAddress("山东青岛");stu.setEmail("kalision@foxmail.com");stu.setId(1);stu.setName("kalision");Birthday day = new Birthday();day.setBirthday("1989-01-25");stu.setBirthday(day);System.out.println(JSONObject.fromObject(stu).toString());}}

输出：

{"address":"山东青岛","birthday":{"birthday":"1989-01-25"},"email":"kalision@foxmail.com","id":1,"name":"kalision"}

当然也可以用JSONArray.fromObject(stu).toString()，JSONSerializer.toJSON(stu).toString()

它们两个的区别大家可以参考另外一篇文章：
