jexcelapi java对excel的操作

文章出处：我的博客 我的生活

Java Excel API(JXL)是一个成熟，开源的Excel电子表格读取，修改，写入的项目。Java开发者利用它简单，便利的API就能够读取Excel电子表格, 进行修改并能够把修改后的变化写到任何output stream中(如：Disk, HTTP, database, 或任何socket),这个项目基于GPL发布,而且对中文有很好的支持。
● 支持字体、数字、日期操作
● 能够修饰单元格属性
● 支持图像和图表
备注：对中文写支持，需要jdk1.5，低版本的jdk或有问题

这里不作多的介绍，可以上网检索一下，会有很多相关介绍，下面举个具体的例子：

public class ExcleServiceImpl extends BaseService implements IExcleService {
/** 行 * */
private static final int ROW = 6;

/** 列 * */
private static final int COL = 0;

public int makeExcle(List okExcle, String sourceFile, String aimFile, String areaName) {
if (okExcle.isEmpty()) {
return -1;
}

int result = 1;
try {
Workbook workbook = Workbook.getWorkbook(new File(sourceFile));
// 拷贝一份excle模版文件
WritableWorkbook copy = Workbook.createWorkbook(new File(aimFile), workbook);
WritableSheet sheet = null;

// 添加的字体样式
WritableFont wf = new WritableFont(WritableFont.TIMES, 16,
WritableFont.BOLD, true);
WritableCellFormat wcfF = new WritableCellFormat(wf);

WritableFont wfTitle = new WritableFont(WritableFont.ARIAL, 12);
WritableCellFormat wcfFTitle = new WritableCellFormat(wfTitle);
wcfFTitle.setBackground(Colour.PALE_BLUE);
wcfFTitle.setBorder(Border.ALL, BorderLineStyle.THIN);

// 做成处理完毕订单的excle
sheet = copy.getSheet(1);
Label labelOK = new Label(2, 1, areaName, wcfF);
sheet.addCell(labelOK);
sheet.addCell(new Label(0, 4, "单号", wcfFTitle));
sheet.addCell(new Label(1, 4, "订单日期", wcfFTitle));
sheet.addCell(new Label(2, 4, "客户名称（工程）", wcfFTitle));
sheet.addCell(new Label(3, 4, "发货仓库", wcfFTitle));
sheet.addCell(new Label(4, 4, "打印装箱单时间", wcfFTitle));

makeOKExcle(okExcle, sheet);

copy.write();
copy.close();
workbook.close();
} catch (Exception e) {
result = 0;
logger.error("Method:makeExcle(...):做成Excle失败！", e);
}

return result;
}

private void makeOKExcle(List list, WritableSheet sheet) {
BasicDynaBean bean;
List valueList = new ArrayList();
Label label = null;

String orderno = "";
String orderdate = "";
String customername = "";
String warehouseid = "";
String printingdate = "";
String handmade = "";
String handmadeFlg = "";

if (list.isEmpty()) {
return;
}

try {
for (int i = 0; i < list.size(); i++) {
bean = (BasicDynaBean) list.get(i);
orderno = convert(bean.get("orderno"));
orderdate = convert(bean.get("orderdate"));
customername = convert(bean.get("customername"));
warehouseid = convert(bean.get("warehouseid"));
printingdate = convert(bean.get("printingdate"));
handmade = convert(bean.get("handmade"));
handmadeFlg = convert(bean.get("handmadeflg"));

valueList.add(orderno);
valueList.add(orderdate);
valueList.add(customername);
valueList.add(warehouseid);
if (handmadeFlg != null && "OK".equals(handmadeFlg)) {
valueList.add(handmade);
} else {
valueList.add(printingdate);
}
for (int j = 0; j < valueList.size(); j++) {
label = new Label(COL + j, ROW + i, (String) valueList
.get(j));
sheet.addCell(label);
}
valueList.clear();
}
} catch (Exception e) {
logger.error("Method:makeOKExcle(...):做成处理完毕的订单Excle失败！", e);
}
}

private String convert(Object object) {
String str = "";
if (object != null && !"".equals(object)) {
str = object.toString();
}
return str;
}
}

List okExcle 是需要写入excel文件的数据源
String sourceFile 源文件
String aimFile 目标文件
String areaName 区域名称（这个和具体业务有关）

这里只是举了个实际项目中的例子，仅作参考
