json学习系列（8）JSON与JAVA数据的相互转换实例

一.完整案例

先定义一个java实体对象，如下:

package com.pcitc.json.cnblog;

/**

 * SimInfo实体对象

 *

 * @Description

 * @author admin

 * @created 2015年6月30日 上午10:23:21

 * @version

 * @history

 * @see

 */

public class SimInfo {

    private String addTime;

    private String iccid;

    private int id;

    private String imei;

    private String imsi;

    private String phoneType;

    private String remark;

    private String tel;

    public String getAddTime() {

        return addTime;

    }

    public void setAddTime(String addTime) {

        this.addTime = addTime;

    }

    public String getIccid() {

        return iccid;

    }

    public void setIccid(String iccid) {

        this.iccid = iccid;

    }

    public int getId() {

        return id;

    }

    public void setId(int id) {

        this.id = id;

    }

    public String getImei() {

        return imei;

    }

    public void setImei(String imei) {

        this.imei = imei;

    }

    public String getImsi() {

        return imsi;

    }

    public void setImsi(String imsi) {

        this.imsi = imsi;

    }

    public String getPhoneType() {

        return phoneType;

    }

    public void setPhoneType(String phoneType) {

        this.phoneType = phoneType;

    }

    public String getRemark() {

        return remark;

    }

    public void setRemark(String remark) {

        this.remark = remark;

    }

    public String getTel() {

        return tel;

    }

    public void setTel(String tel) {

        this.tel = tel;

    }

}

1. json对象转换为java对象

@Test

    public void jsonToJava() {

        String json = "[{\"addTime\":\"2011-09-19 14:23:02\",\"iccid\":\"1111\",\"id\":0,\"imei\":\"2222\",\"imsi\":\"3333\",\"phoneType\":\"4444\",\"remark\":\"aaaa\",\"tel\":\"5555\"}]";

        // 接收{}对象，此处接收数组对象会有异常

        if (json.indexOf("[") != -1) {

            json = json.replace("[", "");

        }

        if (json.indexOf("]") != -1) {

            json = json.replace("]", "");

        }

        // 把字符串形式的JSON串转换成JSON对象

        JSONObject obj = JSONObject.fromObject(json);

        // 把JSON对象转成java对象

        SimInfo simInfo = (SimInfo) JSONObject.toBean(obj, SimInfo.class);

        // 输出java对象的相关属性

        System.out.println(simInfo.getAddTime());

        System.out.println(simInfo.getIccid());

        System.out.println(simInfo.getImei());

        System.out.println(simInfo.getImsi());

        System.out.println(simInfo.getPhoneType());

        System.out.println(simInfo.getRemark());

        System.out.println(simInfo.getTel());

        System.out.println(simInfo.getId());

    }

输出结果:

二. 基于json-lib.jar包Json实例程序的一些总结

1. 把一个JSON字符串转换成JSON对象的两种方式：

String json = "[{\"addTime\":\"2011-09-19 14:23:02\",\"iccid\":\"1111\",\"id\":0,\"imei\":\"2222\",\"imsi\":\"3333\",\"phoneType\":\"4444\",\"remark\":\"aaaa\",\"tel\":\"5555\"}]";

if (json.indexOf("[") != -1) {

            json = json.replace("[", "");

        }

        if (json.indexOf("]") != -1) {

            json = json.replace("]", "");

        }

方式一:

JSONObject obj = JSONObject.fromObject(json);

方式二:

JSONObject obj = (JSONObject) JSONSerializer.toJSON(json);

2. JSONObject to DynaBean

String json = "{name=\"json\",bool:true,int:1,double:2.2}";

JSONObject jsonObject = JSONObject.fromObject(json);

//抽象的写法：DynaBean bean = (DynaBean) JSONSerializer.toJava( jsonObject );

Object bean = JSONObject.toBean(jsonObject);

//Object bean1 = JSONSerializer.toJava(jsonObject);

3. JSONObject to JavaBean

String json = "{name:\"zhangsan\",age:25,hight:1.72,sex:true}";

JSONObject jsonObject = JSONObject.fromObject(json);

UserBean bean = (UserBean) JSONObject.toBean(jsonObject, UserBean.class);

4. JSONArray to List

String json = "[\"first\",\"second\"]";

JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON(json);

List output = (List) JSONSerializer.toJava(jsonArray);

5. JSONArray to array

String json = "[\"first\",\"second\"]";

JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON(json);

JsonConfig jsonConfig = new JsonConfig();

jsonConfig.setArrayMode(JsonConfig.MODE_OBJECT_ARRAY);

Object[] output = (Object[]) JSONSerializer.toJava(jsonArray, jsonConfig);
