老师布置了第二个JAVA作业，让写人事管理系统。

代码思路参考自：清华大学出版设出版的《Java课程设计案例精编（第3版）》

作业是老师在十月一日哦放假前让写的，所以十一回家写了俩界面，然后回到学校老师说先

不做这个，先写一个订餐系统，后来为了参加十一月的区域赛就搁置了这个作业，参加完

区域赛白天还要练题没怎么写，都是晚上快睡觉的时候写了几个界面，断断续续把界面写完

了，这周五、周六一鼓作气把这个给写完了，正好周一上课老师检查。

项目下载地址：https://github.com/wenyaxinluoyang/HRManagement

项目运行环境：

jdk 1.8.0_141

mysql 5.5.27

关于项目几个问题：

1.是否可以把项目发到邮箱？

答：没法发，原因两点，这个代码两三年前写的，那么久远，现在我都毕业工作了，电脑也换了，我没这个代码。

2.关于github的，没有账号的。

答：个知识个代码托管的地方，我记忆中注册好像不需要翻墙，直接去注册就好了，然后去下载代码，

不知道怎么下载，百度一下就好，这些操作都特别简单。

3.关于问题，你的项目在我的环境能够成功运行？

答：纠正一点这个项目下载后一定要配备我说的环境，而不是在你的环境运行。

举个例子：工作的时候，技术总监已经说了我们开发项目要用哪个版本的jdk,框架spring用哪个版本，

我们工作人员也按照要求进行开发，然后可以成功运行我们的代码。当我们把项目部署到服务器的时候，

我们服务器的环境配置的和开发环境是会保持一致的，然后我们的代码才能有最大的可能不发生问题跑起来，

我们绝不会任由喜爱，在服务器上随便安装与开发时候不相同的版本的东西，然后对开发人员说，你的代码

要在这个环境中跑起来。时间推移，版本更新，里面的某些内容发生了改变，万一了以前版本的代码不兼容，

代码将永远跑不起来。

我上学的时候jdk发展到1.8,1.9我们大部分都用1.8

现在，写文章时间为2019.06.23，jdk现在版本发展到1.12， 1.11，可以看到和项目开发时的版本相差

很大了。同样项目中使用的mysql等工具，经过几年的发展，版本更新很快，版本跨度这么大，已经出现

了兼容问题。好多使用我代码的人，配置了较高版本的jdk，结果界面无法显示，都是jdk太高导致的。

4.关于数据库链接问题？

改数据库连接对应的用户名和密码，要到DataOperator中修改。

项目使用mysql作为数据库。如果你更换成sqlserver或oracle，那么数据库驱动也要修改为sqlserver或

oracle的驱动，如果mysql用了与项目不同的版本，请记得修改驱动的对应版本。

5.运行代码时无法显示问题

这个是根据很多人遇到反应的，问题所在jdk版本过高，出现对旧版本代码的兼容问题。

解决方案，换成1.8.0_141或比他不要高太多的版本。

6.关于数据库（指用mysql）改了用户名和密码还报错的。

这是最近一个同学新遇到的问题，我之前没见过。改了用户名和密码后，还提示无法连接数据库，

数据库驱动版本也对，是因为高版本的驱动对应数据库连接的写法与低版本的不同，直接百度

抛出的异常，然后根据网上经验修改连接。

7.关于无法修改员工部门的问题

我代码的bug，在PersonBean中修改员工信息的update语句中我忘记写部门了，大家可以自行加上。

8.建议

建议从下载到环境配置到项目导入自己完成，包括驱动，一切前期工作自己完成。然后认真看

一下代码，代码逻辑非常简单，核心代码就是数据库操作，jdbc编程都是固定格式的，看一个

能明白其他的。然后出现什么问题了可以在留言询问了。本来我在评论区留了我的QQ号，

说起来真是后悔，有些同学什么都不管，每一步都希望我告诉他，包括下载和eclipse导入项目

之类的基本操做，让我觉得有点难以接受。甚至我在上班的时候，在外面朋友聚会的时候都在

QQ上回复大家遇到的问题，我有时会气得都锤桌子了，真的不能什么都依靠作者，自己一点

脑子都不想动。

人事管理系统功能简介：

人事管理系统主要用来实现各种人事管理功能，这些功能包括人员基本信息管理，部门

管理，人员调动管理，人员考核管理以及劳资管理这些模块。

系统功能图：

数据库设计：

员工信息表：Person

未使用员工编号表：unUsedPersonId

部门信息表：DeptTable

未使用部门编号表：unUsedDeptId

人员调动历史表：jobChange

人员考核历史表：assessChange

劳资历史记录表：salaryChange

系统主界面图：(HrMain.java)

可以发现主界面是两个分离面板，将左侧的树形结构和右侧的面板隔开。左侧的树形结构清晰地

表示出了该系统地功能。设计该界面左侧是一个树，人事管理系统是树根root,然后有四个一级节点，

接下来是若干个二级节点（叶子节点）。该界面主要响应的事件有，当点击根节点的时候，显示图中

右侧界面，当点击一级节点的时候，如果该节点没有展开，则先展开该节点。当点击叶子节点的时候

将相应的面板显示在右侧区域中。

1.基本信息管理模块：实现对人员信息的增删查该操作，以及对部门的增删查改操作。

1.1 添加人员信息界面（NodeOnePanelOne.java）

该模块主要实现添加员工信息功能，当点击获取新编号按钮的时候，清空所有文本框，并为欲添加的人员

自动分配一个编号。点击添加按钮的时候，首先判断数据库中不能为空的字段在文本框中是否为空，如果

为有是空的值则拒绝插入，否则插入到Person，并弹出提示信息信息插入成功。

1.2 修改人员信息界面（NodeOnePanelTwo.java）

该模块用来实现信息修改功能，首先通过在Person中查找，将人员的编号和姓名等信息绑定到选择人员信息

下拉列表，然后可以选择人员，选中某个人员后从Person中将该人员的基本信息查找出来，并在文本框显示。

对于性别、出生年月、民族这三个信息由于在通常情况下不常变动，则设置文本框不可修改，其他信息可以

进行修改，点击修改按钮的时候，同样要进行信息的检测，看信息输入是否正确，如果正确则更新表中对应

的记录，否则拒绝更新，点击清空按钮的时候，清空所有文本框内的内容。

1.3 删除人员信息界面（NodeOnePanelThree.java）

该模块用来实现删除员工记录的功能，首先在右侧面板初始化的时候，我们先从Person中查找需要的信息

并显示在右侧，当点中界面中表的一条记录时，将该员工的信息显示在下部文本框中，当点击删除按钮

的时候，删除该记录，并刷新界面。

1.4 查询人员信息界面（NodeOnePanelFour.java）

该界面和上个界面相似，就是将所有员工的信息显示在界面上。

1.5 部门管理界面（NodeOnePanelFive.java）

该界面可以实现部门的增删查改功能。初始化面板的时候，将DeptTable总的所有信息绑定到该界面上，

当点击获取新编号的时候，清空文本框，给欲添加的部门分配一个编号，当点击添加按钮的时候，需要

检测信息输入是否合法。当选中表中的一条记录，将该部门的信息显示在下部文本框中，然后可以对一级

部门和二级部门进行修改，当点击修改按钮的时候，检测信息是否合法，合法则修改并提示用户修改成功，

否则拒绝修改，如果修改成功，则该界面也需要跟着刷新。当点击删除按钮的时候，由于数据库中表的级

联关系， 如果Person表中还有对应部门的员工，则不允许删除，否则可以删除。当点击清空按钮的时候，

清空所有文本框内的内容。

2.人员调动模块：实现对人员工作的调动以及对调动历史的查询。

2.1人员调动：（NodeTwoPanelOne.java）

该模块实现人员部门的调动，从Person表中查询图中字段相应的信息并显示，并从DeptTable表中查询所有

部门并将这些部门绑定到新部门下拉列表框中，选择调入新部门后，更新Person表中的信息，并且将该调动

记录添加到jobChange表中。

2.2调动历史查询（NodeTwoPanelTwo.java）

该界面从jobChange表中读出所有信息并在界面上显示。

3.人员考核管理模块：实现对员工工作的考核，并显示考核记录。

3.1人员考核（NodeThreePanelOne.java）

同样从Person表中取出图中相应的信息并在面板上显示，当选择一条记录的时候，将其信息在下方文本框

显示，点击确定按钮的时候，将Person表中的相关信息更新，并将该考核记录插入assessChange表中。

3.2考核历史查询（NodeThreePanelTwo.java） 

该界面将assessChange表的内容进行显示。

4.劳资管理：用来实现员工工资的调整和劳资历史的查询。

4.1劳资分配管理(NodeFourPanelOne.java)

该模块用来实现员工工资的调整，同样从Person中取出相应的信息并生成表格显示在界面上，当选中一条记录

时，将该记录的信息在下方文本框中显示，点击确定按钮后，更新Person中的信息，弹出修改提示，并将该劳资

历史插入到salaryChange表中。

4.2劳资历史查询（NodeFourPanelTwo.java）

从salaryChange表中取出所有信息在界面上显示。

总结：

虽然这个系统书上有代码，但是并没有直接上手写，在课上一直都是没着手写代码，而是看书上的功能描述，

首先还是分析系统的功能和结构，然后看表的设计，然后思考功能的实现。做什么都得自己先理好思路才能

更好、更快、更正确地写出来。对书上代码做了一些改进。
