java读取2003及2007版的excel

读取excel2003需要使用apache提供的jxl.jar这个jar包：

InputStream is = new FileInputStream(fileDir);

jxl.Workbook rwb = Workbook.getWorkbook(is);

Sheet rs = rwb.getSheet(0);

int rsColumns = rs.getColumns();

int rsRows = rs.getRows();

if (i < rsRows) {

for (int j = 0; j < rsColumns; j++) {

rs.getCell(j, i).getContents();

}

}

读取2007需要使用apache得poi包：

import org.apache.poi.xssf.usermodel.XSSFRow;

import org.apache.poi.xssf.usermodel.XSSFSheet;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

XSSFWorkbook xwb=new XSSFWorkbook(fileDir);

XSSFSheet sheet=xwb.getSheetAt(0);

XSSFRow row;

String cell=null;

int m=0;

int max=0;

for(int i=sheet.getFirstRowNum();i<sheet.getPhysicalNumberOfRows();i++)

{

m=sheet.getRow(i).getPhysicalNumberOfCells();

if (m>=max) {

max=m;

}

else {

}

}

for(int i=sheet.getFirstRowNum();i<sheet.getPhysicalNumberOfRows();i++)

{

Element root_2 = new Element("columns");

root.appendChild(root_2);

row=sheet.getRow(i);

for(int j=0;j<max+1;j++)

{

try {

cell=row.getCell(j).toString();

} catch (Exception e) {

cell=null;

}

Element root_3 = new Element("column");

root_3.appendChild(cell);

root_2.appendChild(root_3);

}

}

Document document = new Document(root);

return document.toXML();
