java简单解析xls文件的方法示例【读取和写入】
本文实例讲述了java简单解析xls文件的方法。分享给大家供大家参考,具体如下:
读取:
importjava.io.*;
importjxl.*;
importjxl.write.*;
importjxl.format.*;
classAa{
publicstaticvoidmain(Stringargs[]){
try{
Workbookworkbook=null;
try{
workbook=Workbook.getWorkbook(newFile("d:\\a.xls"));
}catch(Exceptione){
thrownewException("filetoimportnotfound!");
}
Sheetsheet=workbook.getSheet(0);
Cellcell=null;
intcolumnCount=3;
introwCount=sheet.getRows();
for(inti=0;i
写入:
importjava.io.*;
importjxl.*;
importjxl.write.*;
importjxl.format.*;
classAa{
publicstaticvoidmain(Stringargs[]){
try{
FiletempFile=newFile("d:"+java.io.File.separator+"output00.xls");
System.out.println("d:"+java.io.File.separator+"output00.xls");
WritableWorkbookworkbook=Workbook.createWorkbook(tempFile);
WritableSheetsheet=workbook.createSheet("TestCreateExcel",0);
//一些临时变量,用于写到excel中
Labell=null;
jxl.write.Numbern=null;
jxl.write.DateTimed=null;
//预定义的一些字体和格式,同一个Excel中最好不要有太多格式
WritableFontheaderFont=newWritableFont(WritableFont.ARIAL,12,WritableFont.BOLD,false,UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLUE);
WritableCellFormatheaderFormat=newWritableCellFormat(headerFont);
WritableFonttitleFont=newWritableFont(WritableFont.ARIAL,10,WritableFont.NO_BOLD,false,UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.RED);
WritableCellFormattitleFormat=newWritableCellFormat(titleFont);
WritableFontdetFont=newWritableFont(WritableFont.ARIAL,10,WritableFont.NO_BOLD,false,UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK);
WritableCellFormatdetFormat=newWritableCellFormat(detFont);
NumberFormatnf=newNumberFormat("0.00000");//用于Number的格式
WritableCellFormatpriceFormat=newWritableCellFormat(detFont,nf);
DateFormatdf=newDateFormat("yyyy-MM-dd");//用于日期的
WritableCellFormatdateFormat=newWritableCellFormat(detFont,df);
//剩下的事情,就是用上面的内容和格式创建一些单元格,再加到sheet中
l=newLabel(0,0,"用于测试的Excel文件",headerFormat);
sheet.addCell(l);
//addTitle
intcolumn=0;
l=newLabel(column++,2,"标题",titleFormat);
sheet.addCell(l);
l=newLabel(column++,2,"日期",titleFormat);
sheet.addCell(l);
l=newLabel(column++,2,"货币",titleFormat);
sheet.addCell(l);
l=newLabel(column++,2,"价格",titleFormat);
sheet.addCell(l);
//adddetail
inti=0;
column=0;
l=newLabel(column++,i+3,"标题"+i,detFormat);
sheet.addCell(l);
d=newDateTime(column++,i+3,newjava.util.Date(),dateFormat);
sheet.addCell(d);
l=newLabel(column++,i+3,"CNY",detFormat);
sheet.addCell(l);
n=newjxl.write.Number(column++,i+3,5.678,priceFormat);
sheet.addCell(n);
i++;
column=0;
l=newLabel(column++,i+3,"标题"+i,detFormat);
sheet.addCell(l);
d=newDateTime(column++,i+3,newjava.util.Date(),dateFormat);
sheet.addCell(d);
l=newLabel(column++,i+3,"SGD",detFormat);
sheet.addCell(l);
n=newjxl.write.Number(column++,i+3,98832,priceFormat);
sheet.addCell(n);
//设置列的宽度
column=0;
sheet.setColumnView(column++,20);
sheet.setColumnView(column++,20);
sheet.setColumnView(column++,10);
sheet.setColumnView(column++,20);
workbook.write();
workbook.close();
}catch(Exceptione){
}
}
}
