3.Dao公共类

Dao的全称是Data Access Object，即数据访问对象。本项目中应用该名称作为数据库访问类的名称，在该类中实现了数据库的驱动、连接、关闭和多个操作数据库的方法，这些方法包括不同数据表的操作方法。在介绍具体的数据库访问方

法之前，先来看一下Dao类的定义，也就是数据库驱动和连接的代码。 代码如下

publicclass Dao {

static Statement sql; static ResultSet res;

protectedstatic String dbClassName=\; protectedstatic String

dbUrl=\; protectedstatic String dbUser=\;

protectedstatic String dbPwd=\; protectedstatic String second = null;

publicstatic Connection conn=null;

static{ try{

if(conn==null){

Class.forName(dbClassName).newInstance(); conn = (Connection)

DriverManager.getConnection(dbUrl,dbUser,dbPwd); }

}catch(Exception ee){ ee.printStackTrace();

} }

3.4系统登录模块设计 1.设计登录窗体

登录模块的窗体设计由两部分组成，一部分是登录窗体，另一部分是窗体中带背景图片的内容面板。

1.创建内容面板

publicclassLoginPanelextends JPanel { publicintwidth, height; private Image img; public LoginPanel() { super();

URL url = getClass().getResource(\); img = new ImageIcon(url).getImage(); }

protectedvoid paintComponent(Graphics g) { super.paintComponent(g);

g.drawImage(img, 0, 0, this); } }

2.创建登录窗体

private LoginPanel getLoginPanel() { if (loginPanel == null) { jLabel1 = new JLabel();

jLabel1.setBounds(new Rectangle(86, 71, 55, 18)); jLabel1.setText(\密 码：\); jLabel = new JLabel();

jLabel.setText(\用户名：\);

jLabel.setBounds(new Rectangle(85, 41, 56, 18)); loginPanel = new LoginPanel(); loginPanel.setLayout(null);

loginPanel.setBackground(new Color(0xD8DDC7)); loginPanel.add(jLabel, null);

loginPanel.add(getUserField(), null); loginPanel.add(jLabel1, null);
