java把excel数据写入Oracle数据库，此处需要引入两个文件：ojdbc14.jar，jxl-2.6.10.jar，首先在oracle建立表exceltest,excel文件内容与其对应,此处注意：(excel版本太高了 报错：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.准备好的excel内容(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数据导入到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();
}
}

4.执行效果，查看数据库表：
