如何使用Java编写CMS系统的数据备份功能

import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DataBackup {
    private String backupPath;

    public DataBackup(String backupPath) {
        this.backupPath = backupPath;
    }

    public void executeBackup() throws IOException {
        String directory = createDirectory();
        String fileName = generateFileName();
        // 执行数据备份的逻辑

        // 备份完成后，可以将备份文件的相关信息存储到数据库中，便于后续的管理和查询
    }

    private String createDirectory() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
        String directory = backupPath + File.separator + sdf.format(new Date());
        File dir = new File(directory);
        if (!dir.exists()) {
            dir.mkdirs();
        }
        return directory;
    }

    private String generateFileName() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
        String fileName = sdf.format(new Date()) + ".bak";
        return fileName;
    }
}

public class Main {
    public static void main(String[] args) {
        // 备份文件的存储路径
        String backupPath = "/backup";

        // 创建备份对象
        DataBackup dataBackup = new DataBackup(backupPath);

        // 执行数据备份操作
        try {
            dataBackup.executeBackup();
            System.out.println("数据备份完成！");
        } catch (IOException e) {
            System.err.println("数据备份失败：" + e.getMessage());
        }
    }
}
