java中将字符串或者数组转化为json格式

贴源码

字符串转化为json：

String str = "{\"deviceId\":\"" + listById.get(i).getDeviceid() + "\",\"deviceName\":\"" + listById.get(i).getDeviceName() + "\",\"designer\":\"" + 
listById.get(i).getDesigner()  +"\",\"supervision\":\"" + listById.get(i).getSupervision() + "\",\"construction\":\"" + listById.get(i).getConstruction() + "\" }";

JSONObject jso= new JSONObject,fromObjecrt(str);

josn.put("key",jso);

数组转化为json格式：

List sdList = this.bindService.getSdByUserId(userId);
listById = this.bindService.getBindbyUserId(userId);      
String arr[] = new String[sdList.size()+listById.size()];
for (int i = 0; i < listById.size(); i++) {       
arr[i] = "{\"deviceId\":\"" + listById.get(i).getDeviceid() + "\",\"deviceName\":\"" + listById.get(i).getDeviceName() + "\",\"designer\":\"" + 
listById.get(i).getDesigner()  +"\",\"supervision\":\"" + listById.get(i).getSupervision() + "\",\"construction\":\"" + listById.get(i).getConstruction() + "\" }";      
}
for (int i = 0; i < sdList.size(); i++) {
arr[i+listById.size()] = "{\"deviceId\":\"" + sdList.get(i).getDeviceid() + "\",\"deviceName\":\"" + sdList.get(i).getDeviceName() + "\",\"designer\":\"" +
sdList.get(i).getDesigner() +"\",\"supervision\":\"" + sdList.get(i).getSupervision() + "\",\"construction\":\"" + sdList.get(i).getConstruction() + "\" }";
}

JSONArray json1 = JSONArray.fromObject(arr); 

json.put("result", "0");
json.put("MyDevice",json1);
PrintToJson.print(this.response, json);
