如何在java中创建mysql数据库的备份

ProcessBuilder pb = new ProcessBuilder("mysqldump", "-u", "用户名", "-p密码", "数据库名", "-r", "备份文件路径");

Process process = pb.start();
int exitCode = process.waitFor();

if (exitCode == 0) {
    System.out.println("数据库备份成功！");
} else {
    System.out.println("数据库备份失败！");
}

import java.io.IOException;

public class DatabaseBackup {
    public static void main(String[] args) {
        try {
            ProcessBuilder pb = new ProcessBuilder("mysqldump", "-u", "用户名", "-p密码", "数据库名", "-r", "备份文件路径");
            Process process = pb.start();
            int exitCode = process.waitFor();

            if (exitCode == 0) {
                System.out.println("数据库备份成功！");
            } else {
                System.out.println("数据库备份失败！");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
