1)如何开发一个将excel中的所有数据传输到oracle数据库的软件?
2)Excel工作表中的单元格可能会根据用户提供的输入而有所不同,因此我们必须动态读取excel并根据列值创建临时表?
请建议我如何做,如果可能的话,建议我一个示例链接
提前致谢
使用浏览按钮
读取文件名 fileName = new File(item.getName()).getName();
String filePath = uploadPath + File.separator + fileName;
//System.out.println("File Name : "+fileName);
//System.out.println("File Path : "+filePath);
File storeFile = new File(filePath);
// saves the file on disk
if(fileName != null && fileName.length()>0){
System.out.println("Store File : "+fileName);
item.write(storeFile);
fileInp=item.getInputStream();
阅读给定的Excel文件
System.out.println("Started reading Excel File");
String[] title = new String[6];
String[] val = new String[6];
workbook = new HSSFWorkbook(fileInp);
Sheet worksheet = workbook.getSheetAt(0);
rowCount = worksheet.getLastRowNum();
Row row = worksheet.getRow(0);
Cell col1 = row.getCell((short) 0);
title[0] = col1.getStringCellValue();
Cell col2 = row.getCell((short) 1);
title[1] = col2.getStringCellValue();
Cell col3 = row.getCell((short) 2);
title[2] = col3.getStringCellValue();
Cell col4 = row.getCell((short) 3);
title[3] = col4.getStringCellValue();
Cell col5 = row.getCell((short) 4);
title[4] = col5.getStringCellValue();
Cell col6 = row.getCell((short) 5);
title[5] = col6.getStringCellValue();
for (int i = 1; i <= rowCount; i++) {
row = worksheet.getRow(i);
Cell col;
for (int j = 0; j < 6; j++) {
col = row.getCell((short) j);
if (col != null) {
col.setCellType(HSSFCell.CELL_TYPE_STRING);
val[j] = col.getStringCellValue();
/*
* switch (col.getCellType()) { case
* HSSFCell.CELL_TYPE_STRING: val[j] =
* col.getStringCellValue(); break; case
* HSSFCell.CELL_TYPE_NUMERIC: val[j] =
* col.getNumericCellValue() + ""; break; }
*/
}
}
除此之外,我需要以动态方式执行相同的过程,在上面的情况下,我已经预先定义了列,但是我需要编写一个代码,其中i应该根据列的no来生成表是数据库中的der
