Java代码实现excel数据导入到Oracle
1.首先需要两个jar包jxl.jar,ojdbc.jar(注意版本,版本不合适会报版本错误)
2.代码:
- import java.io.File;
- import java.io.FileInputStream;
- import java.io.IOException;
- import java.io.InputStream;
- import jxl.Cell;
- import jxl.Sheet;
- import jxl.Workbook;
- import jxl.read.biff.BiffException;
- /**
- * excel数据导入到oracle
- * @author sh
- * 2010-05-11
- */
- public class InsertData {
- public static void main(String[] args) throws Exception {
- InsertData in = new InsertData();
- in.insert(“F:/myJob/hah.xls”,“information”);
- }
- /**
- *
- * @param path
- * 要解析的excel文件路径
- * @param dataTable
- * 要写入到数据库中的表名
- * @throws BiffException
- * @throws IOException
- */
- public void insert(String path,String dataTable) throws BiffException, IOException {
- File file = new File(path);
- // 创建新的Excel 工作簿
- Workbook rwb = null;
- rwb = Workbook.getWorkbook(file);
- // 得到工作簿中的第一个表索引即为excel下的sheet1,sheet2,sheet3…
- Sheet sheet = rwb.getSheets()[0];
- int rsColumns = sheet.getColumns();// 列数
- int rsRows = sheet.getRows();// 行数
- String simNumber = “” ;//每个单元格中的数据
- DBUtils jdbc=new DBUtils();
- String str=“”;//拼接要插入的列
- for (int j = 0; j <rsColumns; j++) {
- Cell cell = sheet.getCell(j, 0);
- simNumber = cell.getContents();
- if(j==rsColumns-1){
- str += simNumber ;
- }else{
- str += simNumber+“,”;
- }
- }
- for (int i = 1; i < rsRows; i++) {
- String sql = “insert into “+dataTable+“(“+str+“) values(“;//拼接sql
- System.out.println(str);
- for (int j = 0; j < rsColumns; j++) {
- Cell cell = sheet.getCell(j, i);
- simNumber = cell.getContents();
- if(j==rsColumns-1){
- sql += “‘”+ simNumber+“‘” ;
- }else{
- sql +=“‘”+ simNumber+“‘,”;
- }
- }
- sql += ” )”;
- jdbc.executeUpdate(sql);//执行sql
- }
- jdbc.closeStmt();
- jdbc.closeConnection();
- }
- }
