使用Map<String, String>来接收

Gson gson = new Gson();

String json;
try {
    BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream(), "utf-8"));  
    StringBuffer sb = new StringBuffer("");
    String temp;
    while ((temp = br.readLine()) != null) {
        sb.append(temp);
    }
    br.close();
    json = sb.toString();
    Map<String, String> result = gson.fromJson(json, new TypeToken<Map<String, String>>(){}.getType());
    System.out.println(result.get("name"));
    System.out.println(result.get("id"));
} catch (Exception e) {
    e.printStackTrace();
}
