需求：网站接入qq,sina微博登录，本文最后付效果图：
说明：大部分网站本身是需要用户概念的，很多操作依附于用户，而qq或微博作为一种登录方式指向用户而已，我参考了一下其他网站的做法，
一般有如下两种做法：
1，强制绑定：用户第一次通过qq登录时必须与该网站账户绑定，也就是用户必须要先有一个此网站账户才能登录成功
2，互相独立，用户第一次通过qq登录时直接重新为用户注册一个账户，如以用户名为qq_123456直接注册一个账户，与其他账户无关；
站在用户角度考虑下，可能需要更多的选择性，因此我是如下考虑的:
用户登录后在个人中心中也可设置绑定。
---------------------------------------------------------------------------------------------------
现在大部分第三方的登录OAuth2.0为标准，所以开发流程基本都一致，一般都是一下步骤：
1，申请接入，获取appid&appkey（接入后又第三方发放）
2，用户登录第三方下发token，
3，通过token获取用户唯一标示，一般是一个openId
api地址：
qq:http://wiki.connect.qq.com/api列表
sina：http://open.weibo.com/wiki/授权机制
qq&sina也提供了java sdk
https://github.com/sunxiaowei2014/weibo4j-oauth2-beta3.1.1/
http://qzonestyle.gtimg.cn/qzone/vas/opensns/res/doc/qqConnect_Server_SDK_java_v2.0.zip
sina的虽然开源了，但里面很多代码写的有问题，用的之后需要注意
------------------------------------------------------------------------------------------------------------
数据结构方面需要加以一张表用来维护登录方式和用户关联（通过openId以及登录方式确定唯一性）
网站引入，appid,appkey,回调地址的配置有不再赘述了
代码基本上参照sdk中的demo就可以了，
简单贴一下controller（springMVC架构）中的代码吧
AUthController为父类，存放一些第三方登录的通用方法，BindController为用户绑定提供方法，第三方登录的controller基本上就是一个登录跳转方法，一个回调方法，以及一些接口api的调用

注：该流程为用户首次使用第三方登录时流程
1,登录页面放置第三方登录图标
2，点击图标接入第三方接口，可跳转至第三方登录界面
3，第三方登录完成，用户账户绑定
4，用户登录后，可在个人设置中管理第三方登录的绑定
