JavaFX+Mysql 实现图书管理系统

清疚 2024-03-22 10:34 123阅读 0赞

## 前言 ##

这是一个基于JavaFx+Mysql的图书管理系统，该系统可以实现注册登录功能。  
可以对图书实现增删改查等基本功能，还可以为学生办理借书功能，若书未被借走，则可正常借出；若已被借出，则不能再被借。  
项目完整源代码放在文章末尾。

## 一、页面效果展示 ##

#### 1. 注册页面 ####

## 二、连接数据库 ##

需要插入一个 jar包，然后通过JDBC建立连接。  
（jar包放在文章末尾）\`\`\`\`\`![在这里插入图片描述][3786edb34e884b59be8d76df603ef928.png]

// 先建立连接
    String URL="jdbc:mysql://127.0.0.1:3306/数据库名称?useUnicode=true&characterEncoding=UTF-8&userSSL=false&serverTimezone=GMT%2B8";//jdbc:mysql//服务器地址/数据库名
    String USER=" ";//用户名
    String PASSWORD=" ";//密码
    Connection con=DriverManager.getConnection(URL, USER, PASSWORD); 
    // 接着执行 sql语句
    PreparedStatement pst =con.prepareStatement(sql) ;
    // 查看 sql语句的执行结果
    ResultSet rs = pstexecuteQuery();

## 三、主要功能实现 ##

#### 1.增加信息 ####

// 这个是 点击 增加信息按钮
            b1.setOnAction(new EventHandler<ActionEvent>() {
                @Override
                public void handle(ActionEvent event) {
                    Connection con=null;
    
                        if (a1.getText().isEmpty()||a2.getText().isEmpty()||a3.getText().isEmpty()||a4.getText().isEmpty()||a5.getText().isEmpty()){
                            warn shibai = new warn(stage1,"请输入完整的信息");
                        }else {
    
    
                            try {
                                con = DriverManager.getConnection(DBHelp.URL, DBHelp.USER, DBHelp.PASSWORD);
                            } catch (SQLException throwables) {
                                throwables.printStackTrace();
                            }
                            String sqll= "insert into information (ID,name,press,author,state) values (?,?,?,?,?);";
                            PreparedStatement pst11 = null;
                            try {
                                pst11 = con.prepareStatement(sqll);
                                pst11.setString(1,a1.getText());
                                pst11.setString(2,a2.getText());
                                pst11.setString(3,a3.getText());
                                pst11.setString(4,a4.getText());
                                pst11.setString(5,a5.getText());
                            } catch (SQLException throwables) {
                                throwables.printStackTrace();
                            }
                            try {
                                pst11.executeUpdate();
                            } catch (SQLException throwables) {
                                throwables.printStackTrace();
                            }
    
    
                            stage1.close();
                            stage.close();
                            Mywindow mywindow = new Mywindow();
    
                        }
    
    
                }
            });
        }

#### 2. 预定图书 ####

b1.setOnAction(new EventHandler<ActionEvent>() {
                @Override
                public void handle(ActionEvent event) {
                    if (a1.getText().isEmpty() || a2.getText().isEmpty() || a3.getText().isEmpty()){
                        warn w1 = new warn(stage2," 请输入完整信息!");
                    }else {
                        Connection connection = null;
                        try {
                            connection = DriverManager.getConnection(DBHelp.URL,DBHelp.USER,DBHelp.PASSWORD);
                        } catch (SQLException throwables) {
                            throwables.printStackTrace();
                        }
                        String sql1 = "update information set state=?,lendname=?,lendsex=?,lendnum=? where ID=?;";
                        try {
                            PreparedStatement preparedStatement=connection.prepareStatement(sql1);
                            preparedStatement.setString(1,"已借出");
                            preparedStatement.setString(2,a1.getText());
                            preparedStatement.setString(3,a2.getText());
                            preparedStatement.setString(4,a3.getText());
                            preparedStatement.setString(5,s);
                            preparedStatement.executeUpdate();
                        } catch (SQLException throwables) {
                            throwables.printStackTrace();
                        }
    
                        stage2.close();
                        stage.close();
                        Mywindow mywindow = new Mywindow();
    
    
                    }
                }
            });

#### 3.归还图书 ####

if (s1.equals("存在")){
                warn warn = new warn(stage,"该书已经未被借出!");
            } else if (!s1.equals("存在")){
    
               String sql2 = "update information set state=? , lendname=?,lendsex=?,lendnum=? where ID = ?";
               try {
                   Connection connection1 = DriverManager.getConnection(DBHelp.URL,DBHelp.USER,DBHelp.PASSWORD);
                   PreparedStatement preparedStatement = connection1.prepareStatement(sql2);
                   preparedStatement.setString(1,"存在");
                   preparedStatement.setString(2," ");
                   preparedStatement.setString(3," ");
                   preparedStatement.setString(4," ");
                   preparedStatement.setString(5,s);
                   preparedStatement.executeUpdate();
                   stage1.close();
                   Mywindow mywindow = new Mywindow();
               } catch (SQLException throwables) {
                   throwables.printStackTrace();
               }
    
           }

#### 4.查询图书 ####

String sql3 = "select * from information  where (name like '"+s+"%'||name like '%"+s+"'||name like '%"+s+"%'|| name = '"+s+"')";
    
            Connection connection = null;
            try {
                connection = DriverManager.getConnection(DBHelp.URL,DBHelp.USER,DBHelp.PASSWORD);
            } catch (SQLException throwables) {
                throwables.printStackTrace();
            }
            PreparedStatement preparedStatement = null;
            try {
                preparedStatement = connection.prepareStatement(sql3);
            } catch (SQLException throwables) {
                throwables.printStackTrace();
            }
            ResultSet resultSet = null;
            try {
                resultSet = preparedStatement.executeQuery();
            } catch (SQLException throwables) {
                throwables.printStackTrace();
            }
            if (s.isEmpty()){
                sql3 = "select * from information";
            }
    
                        try {
                            leader_log.mywindow.date(table,sql3);
                        } catch (ClassNotFoundException e) {
                            e.printStackTrace();
    
                        }
    
                }

#### 5. 删除图书 ####

Student row =  table.getSelectionModel().getSelectedItem();
                    if (row == null){
                        warn w2 = new warn(stage,"请选择您要删除的图书!");
                    }else {
                        Connection connection = null;
                        try {
                            connection = DriverManager.getConnection(DBHelp.URL, DBHelp.USER, DBHelp.PASSWORD);
                        } catch (SQLException throwables) {
                            throwables.printStackTrace();
                        }
                        String s = row.getID();
                        String sql1 = "delete from information where ID = ?;";
                        PreparedStatement preparedStatement=null;
                        try {
                            preparedStatement=connection.prepareStatement(sql1);
                            preparedStatement.setString(1,s);
                            preparedStatement.executeUpdate();
                        } catch (SQLException throwables) {
                            throwables.printStackTrace();
                        }
                        stage.close();
                        Mywindow mywindow = new Mywindow();
    
                    }
