java把excel數據寫入Oracle數據庫（.xls文件）（轉）

java把excel數據寫入Oracle數據庫，此處需要引入兩個文件：ojdbc14.jar，jxl-2.6.10.jar，首先在oracle建立表exceltest,excel文件內容與其對應,此處注意：(excel版本太高了 報錯：Exception in thread "main" jxl.read.biff.BiffException: Unable to recognize，把文件保存成excel 97-2003即可)

1.建表

-- Create table
create table EXCELTEST
(
  line1 VARCHAR2(20),
  line2 VARCHAR2(20),
  line3 VARCHAR2(20),
  line4 VARCHAR2(20)
)

2.準備好的excel內容(excel 97-2003)

3.java文件：

package excel;

import java.io.File;
import java.io.IOException;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;

/**
 * excel數據導入到oracle
 * @author

 */
public class excelToOracle {
    public static void main(String[] args) throws Exception {

        excelToOracle in = new excelToOracle();
        in.insert("F:/test.xls","exceltest");

    }

    /**
     *
     * @param path
     *            要解析的excel文件路徑
      * @param dataTable
     *            要寫入到數據庫中的表名
     * @throws BiffException
     * @throws IOException
     */
    public void insert(String path,String dataTable) throws BiffException, IOException {

        File file = new File(path);
        // 創建新的Excel 工作簿
        Workbook rwb = null;
        rwb = Workbook.getWorkbook(file);

        // 得到工作簿中的第一個表索引即爲excel下的sheet1,sheet2,sheet3...
        Sheet sheet = rwb.getSheets()[0];
        int rsColumns = sheet.getColumns();// 列數
        int rsRows = sheet.getRows();// 行數
        String simNumber = "" ;//每個單元格中的數據

        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);//執行sql

        }
        jdbc.closeStmt();
        jdbc.closeConnection();
    }

}
