json

BufferedReader br = new BufferedReader(new InputStreamReader(
                    (ServletInputStream) request.getInputStream()));
            String line = null;
            StringBuffer sb = new StringBuffer();
            while ((line = br.readLine()) != null) {
                sb.append(line);
            }
            String appMsg=sb.toString();

获取到了json字符串,然后就可以转bean了
