DatabaseImportPage为主程序入口

代码逻辑

数据库连接池

引入所需要的包，我这里导入了mysql和oracle的包

接着我们创建mysql数据库连接池

public class MysqlConnection {
    public static Connection connection; // 声明Connection对象
    public MysqlConnection(String url, String username, String password) throws SQLException, ClassNotFoundException {
        Class.forName("com.mysql.cj.jdbc.Driver");
        this.connection = getConnection(url, username, password);
    }
 
 
    public static void main(String[] args) throws SQLException, ClassNotFoundException { // 主方法，测试连接
        String dbAddress = "localhost:3306";
        String dbname = "sqltool";
        String user = "root";
        String password = "shangyi";
        String type = "mysql";
 
        String url = "jdbc:mysql://localhost:3306/sqltool";
 
        MysqlConnection m = new MysqlConnection(url,user,password);
        java.sql.Connection con = m.connection;
 
    }
 
}

oracle数据库连接池

public class OracleConnection {
 
    private static OracleConnection oracleConnection;
    public static Connection connection; // 声明Connection对象
    public OracleConnection(String url, String username, String password) throws SQLException {
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
        } catch (ClassNotFoundException e) {
            throw new RuntimeException(e);
        }
 
        this.connection = DriverManager.getConnection(url, username, password);
    }
 
 
    public static void main(String[] args) throws SQLException { // 主方法，测试连接
    }
}

我们的程序主函数是 DatabaseImportPage，我们在主程序里编写函数与数据库连接池交互

我们先创建了一个Connection对象并设置为null，接着我们根据传入的参数确定他需要oracle和mysql两个连接对象中的哪一个，然后将创建好的连接对象与我们之前创建的Connection连接起来

 
        Connection con = null;
        if (dbtype == "mysql") {
            String url = "jdbc:" + dbtype + "://" + dbAddress + "/" + dbname;
 
            MysqlConnection mysql;
            try {
                mysql = new MysqlConnection(url, user, password);
            } catch (SQLException e) {
                JOptionPane.showMessageDialog(null, "连接失败：" + e.getMessage(), "提示", JOptionPane.ERROR_MESSAGE);
                throw new RuntimeException(e);
            } catch (ClassNotFoundException e) {
                throw new RuntimeException(e);
            }
 
            con = mysql.connection;
 
 
        }else{
            String url = "jdbc:" + dbtype +":thin:@"+dbAddress+":"+dbname;
 
            System.out.println(url);
 
            OracleConnection oracleConnection;
            try {
                oracleConnection = new OracleConnection(url,user,password);
            } catch (SQLException e) {
                JOptionPane.showMessageDialog(null, "连接失败：" + e.getMessage(), "提示", JOptionPane.ERROR_MESSAGE);
                throw new RuntimeException(e);
            }
            con = oracleConnection.connection;
        }

sql文件读取

首先，我们编写文本识别函数

这里我们用到了 juniversalchardet 这个包，他可以帮助我们识别文本的编码格式，这里我们创建一个bufferInputStream对象来读取文本内容，然后创建一个UniversalDetector对象来检测输入的文本，得到结果就结束循环

我们最后返回得到的字符个编码格式

public static Charset detectFileEncoding(String filePath) throws IOException {
        FileInputStream fis = new FileInputStream(new File(filePath));
        BufferedInputStream bis = new BufferedInputStream(fis);
 
        Charset charset = Charset.defaultCharset();
        byte[] buffer = new byte[4096];
        UniversalDetector detector = new UniversalDetector(null);
 
        int bytesRead;
        while ((bytesRead = bis.read(buffer)) != -1) {
            if (detector.isDone()) {
                break;
            }
 
            detector.handleData(buffer, 0, bytesRead);
        }
 
        detector.dataEnd();
        String encoding = detector.getDetectedCharset();
        if (encoding != null) {
            charset = Charset.forName(encoding);
        }
 
        detector.reset();
        bis.close();
        fis.close();
 
        return charset;
    }

接着，我们编写读取和写入文件的代码，以及递归查询文件夹下所有的sql文本的函数

public class FileHandle {
 
    // 读取文本内容
    public static String readFileContent(String filePath,String type) throws FileNotFoundException {
        String encoding = type;
        try {
            Charset fileEncoding = FileEncoding.detectFileEncoding(filePath);
            System.out.println("File Encoding: " + fileEncoding.name());
            encoding = fileEncoding.name();
        } catch (IOException e) {
            System.out.println("Error occurred while detecting file encoding: " + e.getMessage());
        }
 
        StringBuilder content = new StringBuilder();
        FileReader fileHandle = new FileReader(filePath);
 
//        使用系统默认的编码格式读取
//        try (BufferedReader reader = new BufferedReader(new FileReader(filePath)) ) {
//            String line;
//            while ((line = reader.readLine()) != null) {
//                content.append(line).append("\n");
//            }
//        } catch (IOException e) {
//            e.printStackTrace();
//        }
 
        try (BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), encoding))) {
            String line;
            while ((line = reader.readLine()) != null) {
                // 处理每行文本
                content.append(line).append("\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
 
        return content.toString();
    }
 
//  指定格式写入文本
    public static void SaveDate(String sqlFilePath,String text,String type){
        try {
            // 指定文件编码为UTF-8
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(sqlFilePath), type));
 
            // 写入文本到文件
            writer.write(text);
 
            // 关闭文件写入流
            writer.close();
 
        } catch (IOException e) {
            e.printStackTrace();
            System.err.println("写入文件时发生错误：" + e.getMessage());
        }
 
    }
 
    public static List<String> findSqlFiles(File folder) {
        List<String> sqlFilesList = new ArrayList<>();
 
        File[] files = folder.listFiles(new FilenameFilter() {
            @Override
            public boolean accept(File dir, String name) {
                return name.endsWith(".sql");
            }
        });
 
        if (files != null) {
            for (File file : files) {
                // 处理SQL文件，例如读取文件内容
                String filePath = file.getAbsolutePath();
                sqlFilesList.add(filePath);
 
                // 在这里可以使用文件读取方法来读取SQL文件的内容
            }
        }
 
        // 递归处理子文件夹
        File[] subfolders = folder.listFiles(new FileFilter() {
            @Override
            public boolean accept(File pathname) {
                return pathname.isDirectory();
            }
        });
 
        if (subfolders != null) {
            for (File subfolder : subfolders) {
                sqlFilesList.addAll(findSqlFiles(subfolder));
            }
        }
 
        return sqlFilesList;
    }
}

主页面

在主页面中，我们继承JFrame类，实现swing页面

接着我们创建数据库连接对象，再调用文件函数去拿所有的sql文件中的sql语句

然后，将sql语句交给执行函数执行，在执行的过程中，调用进度监督程序ProgressBarPage去实时反馈程序的进度

如果遇到程序出错的情况则启动报错程序DebugPage,去回显相关问题语句

错误处理

在错误处理页面，先根据主页面传递的错误信息进行现场回显，显示错误日志，错误的sql语句，以及报错sql语句的具体位置等信息

用户可以在页面中直接修改该语句，可以选择执行并保存，也可以选择只执行不报错修改内容

如果在执行剩余sql语句的过程中又出现报错，会继续弹出错处处理页面

进度监控

我们实现一个进度条页面，与主程序中的sql执行进度进行交互，通过某一特定数据区传递进度信息，实现实时监控

 
public class ProgressBarPage extends Frame{
 
    private static  ProgressBarPage progressBarPage ;
 
    static JFrame  frame = new JFrame("进度");
    static JProgressBar progressBar = new JProgressBar(0, 100);
 
    static JLabel statusLabel = new JLabel("正在执行：");
 
    private ProgressBarPage(){
        ImageIcon icon = new ImageIcon("src/pic/icon.jpg");
        frame.setIconImage(icon.getImage());
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.setSize(400, 150);
        frame.setLayout(new BorderLayout());
 
        progressBar.setValue(0);
        progressBar.setStringPainted(true);
 
//        frame.add(progressBar);
        frame.add(progressBar, BorderLayout.NORTH); // 将进度条放在上方
        frame.add(statusLabel, BorderLayout.CENTER); // 将状态信息放在中间
 
        // 创建窗口关闭监听器
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
 
                frame.setVisible(true);
            }
        });
 
        frame.setVisible(true);
    }
 
    public static void setProcess(int i){
        progressBar.setValue(i);
    }
 
    public static void setRunningSql(String str){
        statusLabel.setText(str);
    }
 
    public  static ProgressBarPage getProgressBarPage(){
            return new ProgressBarPage();
    }
 
    public static void close(){
        progressBarPage.setVisible(false);
    }
 
    public static class ProgressData {
        private int progress;
        private String sql;
 
        public ProgressData(int progress, String sql) {
            this.progress = progress;
            this.sql = sql;
        }
 
        public int getProgress() {
