CRM項(xiàng)目
一、登錄模塊全程思路分析
登錄模塊：
1、對(duì)用戶名和密碼的校驗(yàn)，并存儲(chǔ)在cookie中，方便后期的免登錄操作。
2、對(duì)用戶基本信息的修改，通過獲取表單用戶修改的數(shù)據(jù)，進(jìn)行Ajax請(qǐng)求，對(duì)修改之后id對(duì)應(yīng)用戶進(jìn)行數(shù)據(jù)庫信息修改
3、修改密碼，獲取用戶輸入的表單數(shù)據(jù)，進(jìn)行service層校驗(yàn)，判斷原密碼，新密碼確認(rèn)密碼，最后對(duì)數(shù)據(jù)庫用戶密碼進(jìn)行修改
4、每次修改信息后會(huì)自動(dòng)清楚cookie內(nèi)的數(shù)據(jù)，退出重新登錄
5、service層會(huì)調(diào)用很多工具類提供便潔業(yè)務(wù)處理

二、營(yíng)銷模塊全程思路分析
營(yíng)銷模塊：
1、主要進(jìn)行營(yíng)銷機(jī)會(huì)的添加、刪除、編輯
2、首先通過靜態(tài)頁面的監(jiān)聽，判斷執(zhí)行什么操作
2.1、點(diǎn)擊添加：對(duì)應(yīng)js調(diào)用addorupdata()方法-->open開啟規(guī)定好大小的頁面，
跳轉(zhuǎn)controller下addorupdata(Integer id,Model model)方法進(jìn)行判斷是
否有id,無則直接轉(zhuǎn)發(fā)靜態(tài)資源頁面addorupdata.ftl頁面，此時(shí)open的小頁面便
有一個(gè)空的表單頁面了。
2.2、點(diǎn)擊修改：對(duì)js調(diào)用addorupdata(id)方法-->open開啟規(guī)定好大小的頁面，
帶id轉(zhuǎn)發(fā)至controller層addorupdata(Integer id,Model model)方法判斷
id是否有值，有則存入對(duì)應(yīng)id的User對(duì)象于model中，轉(zhuǎn)發(fā)至addorupdata.ftl頁
面，此時(shí)open的小頁面便是一個(gè)有內(nèi)容的表單。
2.3、點(diǎn)擊刪除：js文件會(huì)直接調(diào)用deletesale(data),直接獲取要?jiǎng)h除對(duì)象的id,
多個(gè)這返回拼接一個(gè)ids=1&ids=2&ids=3發(fā)送Ajax請(qǐng)求至controller層調(diào)用delete(Integer[] ids)
方法對(duì)其進(jìn)行處理。
3、其次，判斷什么操作之后，便會(huì)彈出對(duì)應(yīng)窗口addorupdata.ftl，此時(shí)對(duì)應(yīng)js對(duì)其監(jiān)聽是否提交
3.1、點(diǎn)擊提交，則會(huì)判斷表單提交數(shù)據(jù)中是否含有id值，有則發(fā)送Ajax請(qǐng)求至controller層
調(diào)用updata(User user)方法對(duì)其進(jìn)行修改。
3.2、點(diǎn)擊提交，id無值，則發(fā)送Ajax請(qǐng)求至controller層調(diào)用add(User user)方法對(duì)其進(jìn)行添加
4、刪除這里直接寫一個(gè)批量刪除即可，無序打開小窗口，直接Ajax請(qǐng)求，調(diào)用controller層的delete方法進(jìn)行處理
其余模塊的邏輯，于營(yíng)銷模塊思路一致，不做更多概述~，源碼直接看上傳資源
