如何使用java在kubernetes pod中创建mysql转储文件

import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class MySQLDump {
    public static void main(String[] args) {
        String url = "jdbc:mysql://mysql-service:3306/dbname";
        String user = "username";
        String password = "password";
        
        try (Connection conn = DriverManager.getConnection(url, user, password);
             Statement stmt = conn.createStatement();
             ResultSet rs = stmt.executeQuery("SELECT * FROM tablename INTO OUTFILE '/path/to/dump/file';")) {
            
            // 使用Java的IO操作将结果写入文件
            Writer writer = new OutputStreamWriter(new FileOutputStream("/path/to/dump/file"), "UTF-8");
            while (rs.next()) {
                // 处理结果集并写入文件
                // ...
            }
            writer.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
