使用Jxl 创建Excel ExcelOS
最近经常使用java操作excel,我选择的是Jxl,感觉比较方便,先分享下我封装的操作类:
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.List;
import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableCell;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.WriteException;
import jxl.write.biff.RowsExceededException;

public class ExportInfoExcelFactory
{
/**
* List 对应不同的sheet,String[]内包含 一个sheet内的一行记录
*/
private List<String[]> headList;
/**
* 外层的list 对应不同的sheet,内部的list 包含一个sheet内所有行的记录, String[]内包含 一个sheet内的一行记录
*/
private List<List<String[]>> bodyList;
private ExportInfoExcelFactory()
{

}
public static ExportInfoExcelFactory getInstance()
{
return new ExportInfoExcelFactory();
}
/**

* @param sheets
* @param bodyList
* @throws RowsExceededException
* @throws WriteException
*/
protected void creatBody(WritableSheet[] sheets,List<List<String[]>> bodyList) throws RowsExceededException, WriteException
{
for(int s=0;s<sheets.length;s++)
{
List<String[]> blist = bodyList.get(s);
int row = 1;
for(String[] strArray : blist)
{
String[] temp = strArray;
for(int col=0;col<temp.length;col++)
{
WritableCell bodyCell = new Label(col,row,temp[col]);
sheets[s].addCell(bodyCell);
}
row++;
}
}
}
