//解析请求的Json数据
private String getRequestPostData(HttpServletRequest request) {
    String response = "";
    try {
        int contentLength = request.getContentLength();
        if (contentLength < 0) {
            return null;
        }
        byte buffer[] = new byte[contentLength];
        for (int i = 0; i < contentLength; ) {
            int len = request.getInputStream().read(buffer, i, contentLength - i);
            if (len == -1) {
                break;
            }
            i += len;
        }
        response = new String(buffer, "utf-8");
    } catch (IOException e) {
        e.printStackTrace();
    }
    return response;
}

然后去调用此方法即可
