Java构造和解析Json数据的两种方法详解一——json-lib

转自：http://www.cnblogs.com/lanxuezaipiao/archive/2013/05/23/3096001.html

在www.json.org上公布了很多JAVA下的json构造和解析工具，其中org.json和json-lib比较简单，两者使用上差不多但还是有些区别。下面首先介绍用json-lib构造和解析Json数据的方法示例。

用org.son构造和解析Json数据的方法详解请参见我下一篇博文：Java构造和解析Json数据的两种方法详解二

一、介绍

JSON-lib包是一个beans,collections,maps,java arrays 和XML和JSON互相转换的包，主要就是用来解析Json数据，在其官网http://www.json.org/上有详细讲解，有兴趣的可以去研究。

二、下载jar依赖包：可以去这里下载

三、基本方法介绍

1. List集合转换成json方法

List list = new ArrayList();
list.add( "first" );
list.add( "second" );
JSONArray jsonArray2 = JSONArray.fromObject( list );

2. Map集合转换成json方法

Map map = new HashMap();
map.put("name", "json");
map.put("bool", Boolean.TRUE);
map.put("int", new Integer(1));
map.put("arr", new String[] { "a", "b" });
map.put("func", "function(i){ return this.arr[i]; }");
JSONObject json = JSONObject.fromObject(map);

3. Bean转换成json代码

JSONObject jsonObject = JSONObject.fromObject(new JsonBean());

4. 数组转换成json代码

boolean[] boolArray = new boolean[] { true, false, true };
JSONArray jsonArray1 = JSONArray.fromObject(boolArray);

5. 一般数据转换成json代码

JSONArray jsonArray3 = JSONArray.fromObject("['json','is','easy']" );

6. beans转换成json代码

List list = new ArrayList();
JsonBean2 jb1 = new JsonBean2();
jb1.setCol(1);
jb1.setRow(1);
jb1.setValue("xx");

JsonBean2 jb2 = new JsonBean2();
jb2.setCol(2);
jb2.setRow(2);
jb2.setValue("");

list.add(jb1);
list.add(jb2);
JSONArray ja = JSONArray.fromObject(list);

四、演示示例

这里以基本的几个常用方法进行测试

package com.json;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

/**
 * 使用json-lib构造和解析Json数据
 *
 * @author Alexia
 * @date 2013/5/23
 *
 */
public class JsonTest {

    /**
     * 构造Json数据
     *
     * @return
     */
    public static String BuildJson() {

        // JSON格式数据解析对象
        JSONObject jo = new JSONObject();

        // 下面构造两个map、一个list和一个Employee对象
        Map<String, String> map1 = new HashMap<String, String>();
        map1.put("name", "Alexia");
        map1.put("sex", "female");
        map1.put("age", "23");

        Map<String, String> map2 = new HashMap<String, String>();
        map2.put("name", "Edward");
        map2.put("sex", "male");
        map2.put("age", "24");

        List<Map> list = new ArrayList<Map>();
        list.add(map1);
        list.add(map2);

        Employee employee = new Employee();
        employee.setName("wjl");
        employee.setSex("female");
        employee.setAge(24);

        // 将Map转换为JSONArray数据
        JSONArray ja1 = JSONArray.fromObject(map1);
        // 将List转换为JSONArray数据
        JSONArray ja2 = JSONArray.fromObject(list);
        // 将Bean转换为JSONArray数据
        JSONArray ja3 = JSONArray.fromObject(employee);

        System.out.println("JSONArray对象数据格式：");
        System.out.println(ja1.toString());
        System.out.println(ja2.toString());
        System.out.println(ja3.toString());

        // 构造Json数据，包括一个map和一个Employee对象
        jo.put("map", ja1);
        jo.put("employee", ja2);
        System.out.println("\n最终构造的JSON数据格式：");
        System.out.println(jo.toString());

        return jo.toString();

    }

    /**
     * 解析Json数据
     *
     * @param jsonString Json数据字符串
     */
    public static void ParseJson(String jsonString) {

        // 以employee为例解析，map类似
        JSONObject jb = JSONObject.fromObject(jsonString);
        JSONArray ja = jb.getJSONArray("employee");

        List<Employee> empList = new ArrayList<Employee>();

        // 循环添加Employee对象（可能有多个）
        for (int i = 0; i < ja.size(); i++) {
            Employee employee = new Employee();

            employee.setName(ja.getJSONObject(i).getString("name"));
            employee.setSex(ja.getJSONObject(i).getString("sex"));
            employee.setAge(ja.getJSONObject(i).getInt("age"));

            empList.add(employee);
        }

        System.out.println("\n将Json数据转换为Employee对象：");
        for (int i = 0; i < empList.size(); i++) {
            Employee emp = empList.get(i);
            System.out.println("name: " + emp.getName() + " sex: "
                    + emp.getSex() + " age: " + emp.getAge());
        }

    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        ParseJson(BuildJson());
    }

}

运行结果如下

五、与org.json比较

json-lib和org.json的使用几乎是相同的，我总结出的区别有两点：

1. org.json比json-lib要轻量得多，前者没有依赖任何其他jar包，而后者要依赖ezmorph和commons的lang、logging、beanutils、collections等组件

2. json-lib在构造bean和解析bean时比org.json要方便的多，json-lib可直接与bean互相转换，而org.json不能直接与bean相互转换而需要map作为中转，若将bean转为json数据，首先需要先将bean转换为map再将map转为json，比较麻烦。

总之，还是那句话—适合自己的才是最好的，大家要按需选取使用哪种方法进行解析。最后给大家介绍两款解析Json数据的工具：一是在线工具JSONEdit（http://braincast.nl/samples/jsoneditor/）；另一个是Eclipse的插件JSON Tree Analyzer，都很好用，推荐给大家使用！
