Javaweb實(shí)現(xiàn)員工信息管理系統(tǒng)

2年前作者：編程小菜雞~~分類：Toy博客閱讀(21)違法舉報(bào)

這篇具有很好參考價(jià)值的文章主要介紹了Javaweb實(shí)現(xiàn)員工信息管理系統(tǒng)。希望對(duì)大家有所幫助。如果存在錯(cuò)誤或未考慮完全的地方，請(qǐng)大家不吝賜教，您也可以點(diǎn)擊"舉報(bào)違法"按鈕提交疑問。

員工信息管理系統(tǒng)

一、項(xiàng)目介紹

1、項(xiàng)目用到的技術(shù)棧

開發(fā)工具：idea
語言：java、js、html+ajax
數(shù)據(jù)庫：MySQL
服務(wù)器：Tomcat
框架：mybatis、jQuery、layui

2、項(xiàng)目實(shí)現(xiàn)功能

管理員、部門負(fù)責(zé)人、員工登錄和退出功能以及用戶注冊(cè)功能（根據(jù)不同的賬號(hào)密碼進(jìn)入不同的頁面，注冊(cè)頁面以及登錄都有校驗(yàn)
管理員可查看公司內(nèi)部所有人員信息，增刪改查員工信息，部門信息，工資調(diào)整、員工請(qǐng)假信息
部門負(fù)責(zé)人可以查看公司內(nèi)部人員信息，本部門內(nèi)人員的請(qǐng)假信息，審批本部門請(qǐng)假信息、增刪改查本部門內(nèi)的員工信息、管理部門內(nèi)員工工資信息
普通職員可以查看所有員工信息，查詢工資、修改密碼、實(shí)現(xiàn)請(qǐng)假功能

3、實(shí)現(xiàn)過程

寫需求分析，畫ER圖
搭建基本結(jié)構(gòu)
構(gòu)建MVC框架
編寫代碼

二、項(xiàng)目展示

1、登錄界面以及用戶注冊(cè)界面

用戶登錄
用戶注冊(cè)界面

2、員工可實(shí)現(xiàn)功能

員工界面首頁
員工請(qǐng)假頁面
員工查詢工資

3、管理員可實(shí)現(xiàn)功能

管理員界面首頁
管理員查看部門信息
管理員查看所有人員賬號(hào)密碼
管理員查看請(qǐng)假信息
管理員修改信息（修改時(shí)信息回顯）

4. 部門負(fù)責(zé)人實(shí)現(xiàn)功能

查詢所有員工信息
查詢本部門員工信息（可修改）
本部門請(qǐng)假信息

三、項(xiàng)目代碼

項(xiàng)目基本結(jié)構(gòu)
數(shù)據(jù)庫表
1. dept表字段：
2. emp表字段：
3. leavetable表字段
4. sal表字段
5. user表字段
