JSON数据处理

问题：JSON数据处理

描述：接收JS传值：JSON串，先用PO类去解析，报错，后发现是数组形式的数据

public ShippingmodelVO buildSaveModeJson(String json) {
	if (json == null) {
		return null;
	}
	ShippingmodelVO shippingmodelVO = new ShippingmodelVO();
	shippingmodelVO = (ShippingmodelVO) com.alibaba.fastjson.JSONObject.parseObject(json, ShippingmodelVO.class);
	return shippingmodelVO;
}

需解释JSON串：

"{ "imglist ":[{ "fileurl ": "g2/M00/02/B7/wKjfnFXLZpHuLCJ9AAT1_ewj8K0778
.jpg "},{ "fileurl ": "g2/M00/02/B7/wKjfnFXLZpWO93EKAAT1_ewj8K0500.jpg "},{ "fileurl ": "g2/M00/02/B7
/wKjfnFXLZprUAhodAASqRMbKzSo930.jpg "}]}"

解决方式：

JSONObject dataObj = JSONObject.fromObject(json);
String datas = dataObj.getString("imglist");
JSONArray array = JSONArray.fromObject(datas);
String arrayString[] = new String[array.size()];
for(int i=0 ;i < arrayString.length;i++)
arrayString[i] = array.getJSONObject(i).getString("fileurl");

整理JAVA中各种数据类型与JSON间的转换：
