java导入excel表到数据库

可以使用Apache POI库来读取Excel文件，然后使用JDBC连接数据库，将数据插入到数据库中。以下是一个简单的示例代码：

import java.io.FileInputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ExcelToDatabase {
    public static void main(String[] args) {
        String jdbcUrl = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";
        String excelFilePath = "data.xlsx";

        try (Connection connection = DriverManager.getConnection(jdbcUrl, username, password);
             FileInputStream inputStream = new FileInputStream(excelFilePath);
             Workbook workbook = new XSSFWorkbook(inputStream)) {

            Sheet sheet = workbook.getSheetAt(0);
            String sql = "INSERT INTO mytable (column1, column2, column3) VALUES (?, ?, ?)";
            PreparedStatement statement = connection.prepareStatement(sql);

            int rowNumber = 0;
            for (Row row : sheet) {
                if (rowNumber == 0) {
                    rowNumber++;
                    continue;
                }

                Cell cell1 = row.getCell(0);
                String column1 = cell1.getStringCellValue();

                Cell cell2 = row.getCell(1);
                int column2 = (int) cell2.getNumericCellValue();

                Cell cell3 = row.getCell(2);
                double column3 = cell3.getNumericCellValue();

                statement.setString(1, column1);
                statement.setInt(2, column2);
                statement.setDouble(3, column3);

                statement.addBatch();

                if (rowNumber % 100 == 0) {
                    statement.executeBatch();
                }
            }

            workbook.close();

            statement.executeBatch();

            System.out.println("Data imported successfully.");

        } catch (Exception e) {
            System.out.println("Error: " + e.getMessage());
        }
    }
}
