java解析sql备份文件，并转换成excel表格

可以使用Java中的JDBC（Java Database Connectivity）技术连接到数据库，并执行SQL语句来解析SQL备份文件。然后可以使用Apache POI（一个Java库）来生成Excel文件并将数据写入其中。

以下是一个简单的示例代码，仅供参考：

import java.io.BufferedReader;
import java.io.FileReader;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class SqlToExcelConverter {
    public static void main(String[] args) {
        String sqlFilePath = "path/to/sql/backup/file.sql";
        String excelFilePath = "path/to/excel/file.xlsx";
        String databaseUrl = "jdbc:mysql://localhost:3306/mydatabase";
        String databaseUser = "root";
        String databasePassword = "password";

        List<String> queries = readSqlQueries(sqlFilePath);
        List<List<String>> data = new ArrayList<>();

        try (Connection conn = DriverManager.getConnection(databaseUrl, databaseUser, databasePassword)) {
            Statement stmt = conn.createStatement();

            for (String query : queries) {
                ResultSet rs = stmt.executeQuery(query);

                while (rs.next()) {
                    List<String> row = new ArrayList<>();
                    for (int i = 1; i <= rs.getMetaData().getColumnCount(); i++) {
                        row.add(rs.getString(i));
                    }
                    data.add(row);
                }
            }

            XSSFWorkbook workbook = new XSSFWorkbook();
            Row headerRow = workbook.createSheet().createRow(0);

            for (int i = 0; i < data.get(0).size(); i++) {
                Cell cell = headerRow.createCell(i);
                cell.setCellValue("Column " + (i + 1));
            }

            int rowIndex = 1;
            for (List<String> row : data) {
                Row dataRow = workbook.getSheetAt(0).createRow(rowIndex++);
                int cellIndex = 0;
                for (String value : row) {
                    Cell cell = dataRow.createCell(cellIndex++);
                    cell.setCellValue(value);
                }
            }

            workbook.write(new FileOutputStream(excelFilePath));
            workbook.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static List<String> readSqlQueries(String sqlFilePath) {
        List<String> queries = new ArrayList<>();
        try (BufferedReader reader = new BufferedReader(new FileReader(sqlFilePath))) {
            StringBuilder queryBuilder = new StringBuilder();
            String line;

            while ((line = reader.readLine()) != null) {
                if (line.trim().endsWith(";")) {
                    queryBuilder.append(line.trim());
                    queries.add(queryBuilder.toString());
                    queryBuilder.setLength(0);
                } else {
                    queryBuilder.append(line.trim());
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return queries;
    }
}
