spring应用中多次读取httppost方法中的流遇到的问题

@RequestMapping("/XXX.do")
  public void XXX(HttpServletRequest request, HttpServletResponse response) throws IOException {
    JSONObject jsonObject = WebUtils.getParameters(request);
　　　　 //业务处理
    ResponseUtil.setResponse(response, MessageFactory.createSuccessMsg());
  }

  public static JSONObject getParameters(HttpServletRequest request) throws IOException {
    InputStream is = null;
    is = new BufferedInputStream(request.getInputStream(), BUFFER_SIZE);
    int contentLength = Integer.valueOf(request.getHeader("Content-Length"));
    byte[] bytes = new byte[contentLength];
    int readCount = 0;
    while (readCount < contentLength) {
      readCount += is.read(bytes, readCount, contentLength - readCount);
    }
    String requestJson = new String(bytes, AppConstants.UTF8);
    if (StringUtils.isBlank(requestJson)) {
      return new JSONObject();
    }
    JSONObject jsonObj = JsonUtils.toJSONObject(requestJson);
    return jsonObj;
  }

/**
 * Web流多次读写过滤器
 *
 * 拦截所有请求，主要是针对第三方提交过来的请求.
 * 为什么要做成可多次读写的流，因为可以在aop层打印日志。
 * 但是不影响controller层继续读取该流
 *
 * 该filter的原理：https://stackoverflow.com/questions/10210645/http-servlet-request-lose-params-from-post-body-after-read-it-once/17129256#17129256
