网站用户注册：
主要实现如下两个功能:
1、用户在网站上注册完成后给用户发一封邮件。
2、用户通过邮件激活后才可以登录。
思路：
首先需要一个思路:
用户在前台点击注册，向controller提交请求，把用户提交过来的信息封装成一个user(需要的信息有name,pwd,email这3个是用户填写的,我们帮用户生成的是id和一个邮箱激活链接地址的唯一标识码acode，还要一个用来识别用户是否已经点击链接的变量active)。 如果用户点击了链接后，我们会将用户的状态修改为true【对应的“”1”】，当我们登入时，会根据返会的actived状态，来判断用户是否已经激活了账户，若未激活，则登录不进去，否则，则可以；
并且不能使用该邮箱重复注册用户，所以每次注册用户时，都会先通过邮箱查询该邮箱是否已经注册过了，没有，则可以注册，否则不行。
用户点了激活链接后，再自动跳转到登录页面！
