【Java】基于SQL数据库系统实现的人力资源管理系统
本学期的数据库课设作业，时间有限界面还有一些基本表没有建立完善。
但还是第一次完整地完成数据库以及相关系统程序设计。
还有JAVA链接所需包（JDBC以及xml.bind.jar）的安装放在下一条博客。
系统设计与功能实现
一.定义主界面类
package edu;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test15 {
public static void main(String[] args) {
JFrame jframe = new JFrame("人力资源管理系统") ;
Dimension d = new Dimension(300,400);
Point p = new Point (250,350);
jframe.setSize(d);
jframe.setLocation(p);
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setVisible(true);
JButton button1 = new JButton("添加");
JButton button2 = new JButton("修改");
JButton button3 = new JButton("查询");
JButton button4 = new JButton("删除");
JButton button5 = new JButton("浏览");
JButton button6 = new JButton("部门");
FlowLayout flow = new FlowLayout(FlowLayout.LEFT,20,30);
JPanel panel = new JPanel(flow);
panel.setSize(300,400);
panel.setBackground(Color.red);
panel.add(button1);
panel.add(button2);
panel.add(button3);
panel.add(button4);
panel.add(button5);
panel.add(button6);
jframe.getContentPane().add(panel);
button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Add add =new Add();
}
});
button2.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Change change =new Change();
}
});
button3.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Ask ask =new Ask();
}
});
button4.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Delete delete =new Delete();
}
});
button5.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Look look =new Look();
}
});
button6.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Db db =new Db();
}
});
}
}
