思路：

1.注冊帳戶時(shí)把用戶存入數(shù)據(jù)庫并且設(shè)置用戶狀態(tài)不可用，同時(shí)給注冊的郵箱發(fā)郵件。

2.郵箱的內(nèi)容應(yīng)該是鏈接到項(xiàng)目的激活方法，并且傳入?yún)?shù)（注冊的郵箱和驗(yàn)證碼）。（http://localhost:8080/email/user/register?action=activate&email=1434244213@qq.com&validateCode=b4dc9b79b75d9aa7d6c332e780a375c2）

3.點(diǎn)擊鏈接會(huì)對(duì)郵箱、驗(yàn)證碼、激活時(shí)間進(jìn)行驗(yàn)證，如果激活成功，更改用戶狀態(tài)為可用。
