jsonObject转jsonArray 可以给jsonObject加个属性,例如：
JSONArray ja = new JSONArray();
String[] str=StrUtil.getStringFromBlob(orderList.get(k).getORDER_PRODUCT_INFO()).split("@\\|@");
for(int i =0;i<str.length;i++){
JSONObject jo =new JSONObject();
String[] strSort=str[i].split("#\\|#");
System.out.println("商品SKU编码："+strSort[1]+"购买此商品的数量"+strSort[4]);
jo.put("sku_id", strSort[1]);
jo.put("stock_num", strSort[4]);
ja.add(jo);
}
JSONObject jsonStockNum=new JSONObject();
jsonStockNum.put("parameter", ja);
JSONObject jsonObject = JSONObject.parseObject(requestData);//解析请求的参数
if(jsonObject != null){
JSONArray jsonArray = jsonObject.getJSONArray("parameter");
if(jsonArray !=null && jsonArray.size() > 0){
JSONObject json = null;
String skuId = "";
String stockNumStr = "";
BigDecimal stockNum = new BigDecimal(0);
//商品sku集合,用于存放商品的sku
List<ProductSkuVO> productSkuList = new ArrayList<ProductSkuVO>();
//商品sku对象
ProductSkuVO productSkuVO = null;
for (int i = 0; i < jsonArray.size(); i++) {
json = jsonArray.getJSONObject(i);
//商品的sku编号
skuId = json.getString("sku_id");
//商品的购买数量
stockNumStr = json.getString("stock_num");
if(StrUtil.isNotNull(stockNumStr)){
stockNum = new BigDecimal(stockNumStr);
}
productSkuVO = new ProductSkuVO();
productSkuVO.setSKU_ID(skuId);
productSkuVO.setSTOCK_NUM(stockNum);
productSkuList.add(productSkuVO);
}
Map<String,Object> parameter = new HashMap<String, Object>();
parameter.put("parameters", productSkuList);
//循环update，回归库存
int count=productSkuService.modifyProductSkuById(parameter);
if(count == jsonArray.size()){
jsonResult.put("code", -1); //批量执行成功
}else{
jsonResult.put("code", 1); //批量执行失败
}
}
//1 字符串装换为对象，使用JSON的parse方法
alert("begin");
var text = '{"a":"1", "b":"2", "c":"3"}';
var jsonObject = JSON.parse(text, null);
alert("The jsonObject value is " +jsonObject.a + ";" + jsonObject.b + ";" + jsonObject.c);
//2 对象转换为字符串，使用JSON的stringify方法
alert(JSON.stringify(jsonObject));
//3 使用eval代替parse方法
var jsonObject2 = eval('(' + text + ')'); //这里直接写 eval(text) 会报错的
alert("The jsonObject2 value is " +jsonObject2.a + ";" + jsonObject2.b + ";" + jsonObject2.c);

//1 json对象转换为字符串

System.out.println("---->" + parseObject.toJSONString());

}
二级树状结构的json拼接：
List<SysProductClassVO> list = sysProductClassService.getSysProductClassByParentClassId(classVO); //查询出根目录
JSONArray jsonParent = new JSONArray();
if(list.size() > 0){
for (SysProductClassVO sysProductParent : list) {
List<SysProductClassVO> childList = sysProductClassService.getSysProductClassByParentClassId(sysProductParent); //根据父类的ID 查询所对应的子类
JSONArray childArray = new JSONArray();
JSONObject childObj = new JSONObject();
if(childList.size()>0){
for (SysProductClassVO sysProuctChild : childList) {
JSONObject jsonChild = new JSONObject();
jsonChild.put("childClassID",sysProuctChild.getCLASS_ID());
jsonChild.put("childClassName",sysProuctChild.getCLASS_NAME());
jsonChild.put("childIntro", sysProuctChild.getINTRO());
jsonChild.put("childClassPath", sysProuctChild.getCLASS_PATH());
jsonChild.put("childOrderNum", sysProuctChild.getORDER_NUM());
jsonChild.put("childSummaryImg", sysProuctChild.getSUMMARY_IMG());
childArray.add(jsonChild);
}
}
childObj.put("childArray", childArray);
childObj.put("parentId", sysProductParent.getCLASS_ID());
childObj.put("parentName", sysProductParent.getCLASS_NAME());
childObj.put("parentImg", sysProductParent.getSUMMARY_IMG());
jsonParent.add(childObj);
jsonResult.put("result", jsonParent);
}
jsonResult.put("code",1); //1代表查询成功并且有数据
jsonResult.put("msg", "成功有数据");
}else{
jsonResult.put("code",0); //1代表查询成功没有数据
jsonResult.put("msg", "成功无数据");
}
得到的格式是：
{
"code": 1,
"msg": "成功有数据",
"result": [
