首先根據(jù)數(shù)據(jù)庫的內(nèi)容創(chuàng)建一個model，賦予所有鍵名，并獲得get和set方法，為了以后檢查方便，最好再設(shè)置toString方法

package com.gjp.Model;public class Model {private int zwid;// idprivate String flname;// 分類名稱private double money;// 金額private String zhangHu;// 賬戶名稱private String createtime;// 創(chuàng)建時間private String description;public int getZwid() {return zwid;}public void setZwid(int zwid) {this.zwid = zwid;}public String getFlname() {return flname;}public void setFlname(String flname) {this.flname = flname;}public double getMoney() {return money;}public void setMoney(double money) {this.money = money;}public String getZhangHu() {return zhangHu;}public void setZhangHu(String zhangHu) {this.zhangHu = zhangHu;}public String getCreatetime() {return createtime;}public void setCreatetime(String createtime) {this.createtime = createtime;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}@Overridepublic String toString() {return "Model [zwid=" + zwid + ", flname=" + flname + ", money=" + money + ", zhangHu=" + zhangHu+ ", createtime=" + createtime + ", description=" + description + "]";}}

鏈接數(shù)據(jù)庫使用到JDBCUtils工具類，這里使用使用工具類進行稍微的修改，因為要存儲漢子，utf8格式

package com.gjp.Utils;import javax.sql.DataSource;import org.apache.commons.dbcp.BasicDataSource;public class JDBCUtils {public static final String DRIVER_CLASS_NAME = "com.mysql.jdbc.Driver";public static final String URL = "jdbc:mysql://localhost:3306/gjp?useUnicode=true&characterEncoding=UTF-8";public static final String USERNAME = "root";public static final String PASSWORD = "liuyang";private static BasicDataSource dataSource = new BasicDataSource();static {dataSource.setDriverClassName(DRIVER_CLASS_NAME);dataSource.setUrl(URL);dataSource.setUsername(USERNAME);dataSource.setPassword(PASSWORD);}public static DataSource getDataSource() {return dataSource;} }

這個程序主要是實現(xiàn)對數(shù)據(jù)庫的增刪改查，在Dao層中實現(xiàn)數(shù)據(jù)庫的操作

package com.gjp.Dao;import java.sql.SQLException; import java.util.ArrayList; import java.util.List;import org.apache.commons.dbutils.QueryRunner; import org.apache.commons.dbutils.handlers.BeanListHandler;import com.gjp.Model.Model; import com.gjp.Utils.JDBCUtils;public class ZhangWuDao {QueryRunner qr = new QueryRunner(JDBCUtils.getDataSource());public List<Model> selectAll() throws SQLException{String sql = "select * from gjp_zhangwu"; return qr.query(sql, new BeanListHandler<Model>(Model.class));}public List<Model> select(String start,String end) throws SQLException{String sql = "select * from gjp_zhangwu where createtime between ? AND ?";Object[] params = {start,end};return qr.query(sql, new BeanListHandler<Model>(Model.class), params);}public void edit(int id,String flname,Double money,String zhangHu,String time,String des) throws SQLException{String sql = "insert into gjp_zhangwu values(?,?,?,?,?,?)";Object[] param = {id,flname,money,zhangHu,time,des};qr.update(sql, param);}public void delAll() throws SQLException{String sql = "delete from gjp_zhangwu";qr.update(sql);}public void delById(int id) throws SQLException{String sql = "delete from gjp_zhangwu where zwid = ?";qr.update(sql,id);}public void add(String flname,double money,String zhangHu,String time,String des) throws SQLException{String sql = "insert into gjp_zhangwu(flname,money,zhangHu,createtime,description) values (?,?,?,?,?)";Object[] param = {flname,money,zhangHu,time,des};qr.update(sql, param);}}

在Service層中實現(xiàn)對數(shù)據(jù)庫的各種操作

package com.gjp.Service;import java.sql.SQLException; import java.util.List;import com.gjp.Dao.ZhangWuDao; import com.gjp.Model.Model;public class ZhangWuService {ZhangWuDao zhangwuDao = new ZhangWuDao();public List<Model> selectAll() throws SQLException{return zhangwuDao.selectAll();}public List<Model> select(String start,String end) throws SQLException{return zhangwuDao.select(start, end);}public void edit(int id,String flname,Double money,String zhangHu,String time,String des) throws SQLException{zhangwuDao.edit(id, flname, money, zhangHu, time, des);}public void delAll() throws SQLException{zhangwuDao.delAll();}public void delById(int id) throws SQLException{zhangwuDao.delById(id);}public void add(String flname,double money,String zhangHu,String time,String des) throws SQLException{zhangwuDao.add(flname, money, zhangHu, time, des);} }

接下來就是各個界面的具體內(nèi)容

1.主頁面 這里沒有什么要說的，就是一個簡單的可以選擇功能的跳轉(zhuǎn)窗口

package com.gjp.View;import java.awt.EventQueue;import javax.swing.JFrame; import java.awt.Toolkit; import javax.swing.JLabel; import javax.swing.ImageIcon; import java.awt.Font; import java.awt.Color; import javax.swing.JButton; import java.awt.event.ActionListener; import java.io.File; import java.awt.event.ActionEvent;public class Index {private JFrame frame;private final JLabel lblNewLabel = new JLabel("");/*** Launch the application.*/public static void index() {EventQueue.invokeLater(new Runnable() {public void run() {try {Index window = new Index();window.frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}/*** Create the application.*/public Index() {initialize();}/*** Initialize the contents of the frame.*/private void initialize() {frame = new JFrame();frame.setTitle("管家婆記賬系統(tǒng)");frame.setResizable(false);frame.setBounds(550, 200, 892, 589);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.getContentPane().setLayout(null);JLabel label = new JLabel("歡迎進入管家婆記賬軟件");label.setForeground(Color.DARK_GRAY);label.setFont(new Font("宋體", Font.PLAIN, 45));label.setBounds(174, 42, 532, 55);frame.getContentPane().add(label);JButton btnNewButton = new JButton("好的");btnNewButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent arg0) {Function function = new Function();function.function();frame.dispose();}});btnNewButton.setFont(new Font("宋體", Font.PLAIN, 30));btnNewButton.setBounds(701, 476, 171, 55);frame.getContentPane().add(btnNewButton);lblNewLabel.setIcon(new ImageIcon("F:\\Eclipse_Java\\gjp.jpg"));lblNewLabel.setBounds(0, 0, 885, 553);frame.getContentPane().add(lblNewLabel);} }

2.查詢窗口，這個窗口實現(xiàn)了查詢和條件查詢，具體的實現(xiàn)過程就是在窗口中加一個JTable插件在其中設(shè)置他的model值，條件查詢時，修改其中的model即可，注意這個窗口中查出來的內(nèi)容不能修改。

3.刪除 根據(jù)id值刪除，在這里我封裝了一個類isNumber，用來判斷id值是否為int類型

package com.gjp.View;import java.awt.EventQueue; import java.awt.Font; import java.sql.SQLException; import java.util.List;import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTable; import javax.swing.JTextField; import javax.swing.table.DefaultTableModel;import com.gjp.Model.Model; import com.gjp.Service.ZhangWuService;import javax.swing.JButton; import javax.swing.JScrollPane; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; import java.awt.Color;public class Delete {private JFrame frame;private JTable table;private JLabel lblid;private JLabel lblId;private JTextField textField;private String[] Names = { "id", "用途", "金額", "賬戶", "創(chuàng)建時間", "說明" };ZhangWuService zhangwu = new ZhangWuService();List<Model> list1 = zhangwu.selectAll();Object[][] data = new Object[list1.size()][Names.length];private JLabel label_1;private isNumber isnumber = new isNumber();private static int con = 0;/*** Launch the application.*/public static void delete() {EventQueue.invokeLater(new Runnable() {public void run() {try {Delete window = new Delete();window.frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}/*** Create the application.* * @throws SQLException*/public Delete() throws SQLException {initialize();}/*** Initialize the contents of the frame.* * @throws SQLException*/private void initialize() throws SQLException {frame = new JFrame();frame.setResizable(false);frame.setBounds(550, 200, 892, 589);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.getContentPane().setLayout(null);table = new JTable();table.setFont(new Font("宋體", Font.PLAIN, 22));table.setBounds(0, 113, 874, 431);table.setRowHeight(30);frame.getContentPane().add(table);DefaultTableModel model = new DefaultTableModel(query(list1), Names);table.setModel(model);lblid = new JLabel("請輸入id刪除");lblid.setFont(new Font("宋體", Font.PLAIN, 25));lblid.setBounds(34, 26, 176, 34);frame.getContentPane().add(lblid);lblId = new JLabel("id：");lblId.setFont(new Font("宋體", Font.PLAIN, 23));lblId.setBounds(280, 53, 72, 27);frame.getContentPane().add(lblId);textField = new JTextField();textField.setFont(new Font("宋體", Font.PLAIN, 23));textField.setBounds(316, 58, 86, 24);frame.getContentPane().add(textField);textField.setColumns(10);JButton button = new JButton("刪除");button.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {String ids = textField.getText();int min = (Integer) model.getValueAt(0, 0);int max = (Integer) model.getValueAt(list1.size()-1, 0); // System.out.println(isnumber.isNumber(ids));if (isnumber.isNumber(ids)) {int id = Integer.parseInt(ids);if (id < min || id > max) {label_1.setText("請輸入有效id！");} else {label_1.setText("");try {List list2 = zhangwu.selectAll();for(int i = 0;i < list2.size();i++){model.removeRow(0);System.out.println("yes");}zhangwu.delById(id);list1 = zhangwu.selectAll();data = query(list1);System.out.println(list1);for(int j = 0;j < list1.size();j++){model.addRow(data[j]);}} catch (SQLException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}}}else{label_1.setText("請輸入數(shù)字！");}}});button.setFont(new Font("宋體", Font.PLAIN, 23));button.setBounds(431, 51, 123, 31);frame.getContentPane().add(button);JScrollPane scrollPane = new JScrollPane();scrollPane.setBounds(858, 113, 16, 431);frame.getContentPane().add(scrollPane);label_1 = new JLabel("");label_1.setForeground(Color.RED);label_1.setFont(new Font("宋體", Font.PLAIN, 24));label_1.setBounds(34, 73, 210, 27);frame.getContentPane().add(label_1);JLabel label = new JLabel("");label.setIcon(new ImageIcon("F:\\Eclipse_Java\\gjp.jpg"));label.setBounds(0, 0, 885, 553);frame.getContentPane().add(label);}public Object[][] query(List<Model> list) throws SQLException {for (int i = 0; i < list.size(); i++) {for (int j = 0; j < Names.length; j++) {data[i][0] = list.get(i).getZwid();data[i][1] = list.get(i).getFlname();data[i][2] = list.get(i).getMoney();data[i][3] = list.get(i).getZhangHu();data[i][4] = list.get(i).getCreatetime();data[i][5] = list.get(i).getDescription();}}return data;} }

4.修改 先實現(xiàn)查詢功能，查詢出來后直接在table中修改
