第三方登录，首先需要设计扩展性的表结构。参照如下：本文主要写第三方登录的代码。

浅谈数据库用户设计：http://www.cnblogs.com/jiqing9006/p/5937733.html

可绑定可扩展的账号系统：http://blog.cocosdever.com/2016/03/08/The-design-principle-and-implementation-of-extensible-account-system-1/

第三方登录流程是：先获取code---->然后获取access\_token----->根据token获取用户信息。

前台页面实现步骤：点击微博登录按钮---->打开一个子窗口，进行授权------>授权完成，跳转到首页或上次浏览的页面。

1、写第三方登录的按钮，点击按钮时，打开一个子窗口。

redirect\_uri是你在微博上设置的回调地址。

      </body>
    </html>

2、回调地址页（qq.jsp、weibo.jsp）

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    
    String code = request.getParameter("code");//获取QQ返回的code
    String state = request.getParameter("state");
    %>
    <!DOCTYPE HTML>
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'weibo.jsp' starting page</title>
        
        <meta http-equiv="pragma" content="no-cache">

        <script type="text/javascript" src="http://statics.2cto.com/js/jquery.min.js"></script>
        <script>
            $(function(){
                    var code = "<%=code%>";
                    var state = "<%=state%>";
                    $.ajax({
                        url:"http://localhost:8080/cms_manage/api/qqLogin",
                        type:"post",
                        data:{code:code,state:state},
                        dataType:"json",
                        success:function(result){
                            result = JSON.stringify(result);
                            console.log(result);
                            //把返回的数据传给父窗口的隐藏域中
                            window.opener.document.getElementById("qq").value = result;
                            //授权完成后，关闭子窗口
                            window.opener.closeQQWin();
                        }
                    });
            });
        </script>
      </head>
      
      <body>
            登录成功。
      </body>
    </html>

qq.jsp和weibo,jsp是一样的。。。
