//2.用戶填寫資料，點(diǎn)擊注冊(cè)，插入數(shù)據(jù)成功，state字段默認(rèn)是0,同時(shí)生成一個(gè)ActiCode（用傳過來的郵箱、密碼、和當(dāng)前時(shí)間加密形成）也存入數(shù)據(jù)庫
//3.發(fā)送郵件。。。提示用戶登錄郵箱激活。。。郵件中帶一個(gè)激活成功頁的URL，URL里有兩個(gè)參數(shù)（1，用戶ID，2：激活碼）
//4.用戶登錄郵箱點(diǎn)擊鏈接，來到處理激活的業(yè)務(wù)邏輯頁面或Servlet，得到URL中兩個(gè)參數(shù)，以這兩個(gè)參數(shù)為條件查詢數(shù)據(jù)庫里的數(shù)據(jù)，如果有，取當(dāng)前時(shí)間和之前存入數(shù)據(jù)庫的過期時(shí)間作比較，看是否過期，過期，刪除數(shù)據(jù)庫中該條記錄，并轉(zhuǎn)到失敗頁面，沒過期，查看鏈接傳過來的激活碼與數(shù)據(jù)庫字段激活碼是否一致，不一致，同樣刪除數(shù)據(jù)庫中該條記錄，并跳轉(zhuǎn)到激活失敗界面，一致，則將字段state為1，激活成功，轉(zhuǎn)到激活成功頁。。。
二、具體實(shí)現(xiàn)代碼
1.首先，準(zhǔn)備一個(gè)簡(jiǎn)單的測(cè)試頁面
<body> <div id=”main” style=”margin:0 auto;width:500px;”> <form id=”reg” action=”user.action?op=reg” method=”post”> <p> E-mail：<input type=”text” class=”input” name=”email” id=”email”> </p> <p> 密 碼：<input type=”password” class=”input” name=”pwd” id=”pwd”> </p> <p> <input type=”submit” class=”btn” value=”提交注冊(cè)” > </p> </form> </div> </body>
2.點(diǎn)擊提交注冊(cè)，來到user.action?op=reg，注意帶的參數(shù)op指我要做的操作，用于后面的Servlet做判斷該做什么操作，下面的代碼完成了形成激活碼、過期時(shí)間等表示當(dāng)前注冊(cè)用戶的狀態(tài)的信息存入數(shù)據(jù)庫并發(fā)送郵件的過程。（郵件內(nèi)容自定義，可以忽略我的）

這是QQ郵箱設(shè)置，一般開啟1、2、4
這是收到的激活郵件
根據(jù)用戶所填郵箱跳轉(zhuǎn)相應(yīng)郵箱登錄地址的代碼
