本项目的文件组织结构：https://github.com/OOMMYY/EM
一个数据库连接的javaBean 一个过滤脚本的工具类，其他的除了登录界面login.html外都是jsp界面
login.html 包含提交登录信息的表单，特别要注意的是页面编码问题，在本项目中，所有的编码格式统一为UTF-8;
1 <html> 2 <style > 3 #login{ 4 position:absolute; 5 top:310px; 6 left:550px; 7 backgroud-color:blue; 8 <!--background-image: url(login.png);--> 9 } 10 #body{ 11 background-color: rgb(0,120,255); 12 <!--background-image: url(login.png);--> 13 } 14 h1 {font-size:3.75em;} 15 </style> 16 <head> 17 <meta http-equiv="content-type" content="text/html; charset=UTF-8"> 18 </head> 19 <body ID="body"> 20 <h1 align="center">欢迎登录人事管理系统</h1> 21 <div id="login"> 22 <form action="login.jsp" method="post"> 23 <p>user name: <input type="text" name="username" required="required" /></p> 24 <p>Password: <input type="password" name="password" required="required" /></p> 25 <p align="center"><input type="submit" value="login" /></p> 26 </form> 27 </div> 28 </body> 29 </html>
login.jsp 处理登录界面提交的表单
<%@ page language="java" contentType="text/html; charset=UTF-8"%> <%@ page import="java.util.*,java.text.*"%> <%@ page import="java.sql.*,util.*"%> <style> * {font-family: "宋体";font-size: 14px} </style> <center> <jsp:useBean id="db" scope="page" class="util.DB" /> <% Boolean flag=false; String username=request.getParameter("username"); String password=request.getParameter("password"); String sql = "select Password from users where EmployeeID ="+username; Connection conn = null; response.setContentType("text/html;charset=utf-8"); try { conn = db.getConn(); Statement pstmt = db.getStmt(conn); ResultSet rs = db.getRs(pstmt,sql); if(rs.next()){ String pwd=rs.getString("PassWord"); if(password.equals(pwd)){ out.println("登陆成功"); flag=true; } } if(!flag){ out.println("登陆失败"); } rs.close(); pstmt.close(); } catch (SQLException e) { e.printStackTrace(); } finally { try { conn.close(); } catch (SQLException e) { e.printStackTrace(); } } if(!flag) response.sendRedirect("login.html"); else{ session.setAttribute("ID",username); response.sendRedirect("menu.jsp"); } %> </center>
处理登录账户信息后确定用户是否合法，如果合法就转到menu.jsp;否则返回登录界面。
menu界面分三个部分，第一部分是：导航栏
第二部分是一个内置框架，用于信息显示
第三部分就是一张图片资源

在本模块还加入了改密码的功能
personalPassword.jsp是改密码的界面，该界面会提交一个包含旧密码，新密码，确认密码的表单

这个模块实现对数据库userrole表的查询和编辑功能，uerrole.jsp把数据库中的userrole表查询一遍，返回并显示结果，这里面的连接数据库时分四步.1、加载数据库驱动；2、连接数据库；3、创建会话获得结果集；4、关闭结果集与会话，断开数据库连接。注意在整个过程中要对可能出现的异常情况进行处理，在该项目中，数据库的连接操作被封装在一个javaBean中（DB.java）DB.java
在jsp中进行数据库操作之前，先实例化DB <jsp:useBean id="db" scope="page" class="util.DB"/>
DB中对数据库进行操作的方法有：获得连接 getConn();获得会话 getStmt();获得数据集 getRS();关闭连接 closeConn();关闭会话 closeStmt();关闭数据集 closeRs();

主要部分training_query.jsp输出培训信息，并能够根据权限选择性输出管理培训信息的入口;添加培训信息training_add.jsp;编辑培训信息training_editHandler.jsp;后台更新数据库training_editHandler.jsp。
这个部分的设计结构与培训管理模块一样，考核主界面evaluation_query.jsp。添加考核信息evaluation_addHandler.jsp;编辑考核信息evaluation_editHandler.jsp。
本部分与上两部分模式一样,稍有不同的是本模块没有编辑功能，但是有删除功能。奖惩信息主界面rewardandpunishment_query.jsp,添加奖惩信息rewardandpunishment_addHandler.jsp,删除奖惩信息rewardandpunishment_deleteHandler.jsp;
本部分有特点的是角色的各种权限信息用多选框显示出来了，不再是以文本框的形式输出了。角色管理主界面roler_query.jsp，修改角色的权限roler_editHandler.jsp,roler_addHandler.jsp处理添加角色及勾选相应拥有权限。
本模块也是只有具有密码管理权限的用户才能够进来的界面。password_query.jsp是密码管理界面,password_editHandler.jsp修改员工密码后更新后台数据库。

加密系统权限 |
本系统支持基于角色的访问控制。正如在业务模块的简介中所述，用户只有拥有某一业务模块的操作权限才能进行相关操作。而用户的权限来源于系统角色，即用户只能从所属的角色中获得若干权限，而本身无法被授权，授权只能对角色进行，即所谓“基于角色的访问控制”。具体的设计原则为：
1. 为每个模块设置独立的权限
业务模块和系统权限呈一一对应关系。拥有该业务模块的权限后，即可对该模块的数据进行全部操作（增、删、改、查等）。
业务模块和系统权限的对应关系如下表所示：
|

2. 将系统角色作为权限授予和撤销的基本单位
l 用户没有任何权限
l 用户获得所属角色的权限
l 用户与角色、角色与权限均呈多对多关系
l 当用户属于多个角色时，其权限为各角色权限的并集
3. 角色管理和权限管理的分离
l 只拥有角色管理权限的用户，不能管理用户角色，而无法直接控制用户的权限。
l 只拥有权限管理权限的用户，只能将用户添加到现有的角色中或移除用户的当前角色，而无法控制角色的权限。
