java后台接收json數據 以及將json轉成map

//獲取json對象
BufferedReader br = new BufferedReader(new
        InputStreamReader(req.getInputStream(), "UTF-8"));
String line = null;
StringBuilder sb = new StringBuilder();
while ((line = br.readLine()) != null) {
    sb.append(line);
}
String reqBody = sb.toString();

//轉成map
Map maps = (Map) JSON.parse(reqBody)
