功能说明

基于javaweb的JSP+Servlet人事HR管理系统(java+servlet+jsp+jquery+easyui+ztree+mysql)

项目介绍

本项目为基于jsp的HR人事管理系统，可以完美运行。 主要分为超级管理员与普通管理员两种角色； 管理员主要功能包括： 系统管理员：管理员管理、修改密码； 部门信息管理：部门信息添加、部门信息查询； 员工信息管理：新员工登记、员工信息查询； 合同信息管理：合同信息添加、合同信息查询； 考勤信息管理:员工请假信息查询审核、考勤信息添加、考勤信息查询； 工资信息管理：工资信息添加、工资信息查询； 应聘信息管理：应聘信息添加、应聘信息查询； 调职信息管理：调职信息添加、调职信息查询； 离职信息管理：离职信息添加、离职信息查询； 复职信息管理：复职信息添加、复职信息查询； 系统管理； 普通管理员无法对管理员账号信息修改，其它功能类似；

环境需要

1.运行环境：java jdk 1.7;注：本项目目前仅支持jdk 1.7； 2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA; 3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可 4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；  5.数据库：MySql 5.7、8.0等版本均可； 6.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目

技术栈

1. 后端：Servlet 2. 前端：JSP+css+javascript+jQuery+easyUI+ztree

使用说明

1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven; 若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行； 3. 将项目中db.properties配置文件中的数据库配置改为自己的配置; 4. 运行项目，在浏览器中输入http://localhost:8080/login.jsp 登录 超级管理员账号密码：hsg/hsg 普通管理员账号密码：ldx/ldx
