如何从Excel读取SQL查询并传递给JDBC代码

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileInputStream;
import java.sql.*;

public class ExcelToJDBC {
    public static void main(String[] args) {
        String excelFilePath = "path/to/excel/file.xlsx";
        String sheetName = "Sheet1";

        try {
            FileInputStream fis = new FileInputStream(excelFilePath);
            Workbook workbook = new XSSFWorkbook(fis);
            Sheet sheet = workbook.getSheet(sheetName);

            // Assuming the SQL query is in the first cell of the first row
            Row firstRow = sheet.getRow(0);
            Cell firstCell = firstRow.getCell(0);
            String sqlQuery = firstCell.getStringCellValue();

            // JDBC connection
            String jdbcUrl = "jdbc:mysql://localhost:3306/database";
            String username = "username";
            String password = "password";
            Connection connection = DriverManager.getConnection(jdbcUrl, username, password);

            // Execute SQL query
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(sqlQuery);

            // Process the result set
            while (resultSet.next()) {
                // Do something with the data
            }

            // Close resources
            resultSet.close();
            statement.close();
            connection.close();

            workbook.close();
            fis.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
