Java中JSON格式的解码与编码(2)

本文主要实验从map转为json,从javabean转为json,以及从json转为javabean

javabean

package com.lql;import java.util.Arrays;public class Student {private String name;private int age;private String[] skills;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[] getSkills() {return skills;}public void setSkills(String[] skills) {this.skills = skills;}@Overridepublic String toString() {return "Student [name=" + name + ", age=" + age + ", skills="+ Arrays.toString(skills) + "]";}}

解析类

package com.lql;import java.util.HashMap;import java.util.Map;import net.sf.json.JSONObject;public class JSONParse {public static void main(String[] args) {// map 转为jsonMap map = new HashMap();map.put("name", "zhangsan");map.put("age", 20);map.put("skills", new String[]{"java","php"});JSONObject jsonObject = JSONObject.fromObject(map);System.out.println(jsonObject);// bean转化为jsonStudent student = new Student();student.setName("zhangsan");student.setAge(20);String[] skills = {"java", "php"};student.setSkills(skills);JSONObject jsonObject2 = JSONObject.fromObject(student);System.out.println(jsonObject2);// json转化为beanString json = "{'age':20,'name':'zhangsan','skills':['java','php']}";JSONObject jsonObject3 = JSONObject.fromObject(json);Student student2 = (Student) JSONObject.toBean(jsonObject, Student.class);System.out.println(student2);}}
